Calibration fails on the 371 SPL Computer.

Calibration can fail if the Sense Input Gain is set too low (–45 dB) or too high (+20 dB). In the LCD setup menus, adjust Sense Input Gain for a proper gain setting. Check Sense for the current sense input level. The setting should be between -45 dB and +20 dB. You can also check the SENSE INPUT by listening with headphones connected to AMBIENT SENSE MONITOR on the front panel to hear what the 371 is reading.

How do I get audio between units using SymLink?

Use the SymLink Bus Sends/Returns, which can be found in the ToolKit at the left side of the SymNet Designer screen. SymLink Bus Sends/Returns are also used to bus Control Signals.

Why is the audio output of my 372 SPL Computer being interrupted?

Because the 372 SPL Computer uses the speakers of a sound system as sensing microphones, the sound?system is briefly disabled (~250 milliseconds) every time a reading is taken.

Where can I find Schematics for the 305 Distribution Amplifier (1x4)?

How does the averaging time work on the 372 SPL Computer?

The 372 SPL Computer can be set to 1, 2, 4, or 8 and average together the number of samples to make a gain changes. After a calibration the sample buffer is cleared and set to the same relative level taken during the calibration. In other words if the 372 is set to 4 samples and calibrated at -30dB relative and during the first sample it reads -20dB it would average -20dB, -30dB, -30dB and -30dB to determine the gain change.

Where can I find Schematics for the 301 Low Distortion Compressor / Limiter?

Is there a recommended microphone for use with the 371 SPL Computer?

For most applications, an inexpensive low-impedance, omnidirectional microphone, such as a lavaliere microphone works adequately. Some installers have used boundary microphones with good success (they’re unobtrusive). Other installers have mounted microphone cartridges (available from Mouser Electronics in the U.S.) inside electrical boxes equipped with a single-holed cover. In smaller rooms or acoustically live spaces, a directional microphone is a good choice, because you can use its position to favor the ambient sound and minimize pickup from the sound system loudspeakers. If the sense mic is positioned a relatively long distance from the ambient noise source(s), a directional microphone may improve system performance.

The announcer's voice sounds "hollow" when we use the TI-101 Telephone Interface.

Under normal conditions you will notice leakage of the host audio into the caller audio. This is the nature of analog hybrids. When properly adjusted, the caller’s audio level should be 3 to 6dB higher than the host audio leakage. Since this leakage is out of phase with the source audio a change in tonal quality is normal.

My speakers are rated for 50 watts, why did the 420 Stereo Power Amplifier damage them?

An under powered speaker can be just as damaged as an over powered speaker. When an amplifier is driven into clipping or square wave it is essentially asking the speaker cone to go full out (+) then full in (-) in zero time.

What is the stereo separation on the 450 Dual Zone Priority Mixer?

Greater than -60 dB when measured at 1000 Hz.

Greater than -35 dB when measured with a 18 kHz tone.

Where can I find a User's Guide for the SSG192 High Definition Studio Sync Generator?

Does the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter dither?

No, there is no dithering on either the AES3, S/PDIF or ADAT digital outputs. It is recommended that dithering be performed (by external equipment) subsequent to bit depth reduction. In practice, truncating to 20-bits produces very low levels (<114dBFS) of truncation distortion, which is beyond the SNR of the converters, and can often be performed without audibility. Truncation to 16-bits can product audible distortion, and is not recommended.

Will SymNet SymLink and Express hardware work with AMX or Crestron control systems?

Yes. There is a dedicated RS-232 port on the rear panel of all 8×8, 8in, 8out, DigIO and CobraLink units for this purpose. This port can be used simultaneously with the host computer connected to the front panel RS-232 port, and the rear panel RS-485 port. The Express units have a dual-purpose rear panel port. The control protocol documentation is available for download from Documentation link in the Support section of this website. The protocol can also be found in the online Help section of the SymNet Designer application.

What are some DigIO 12x12 DSP applications?

Home Theater and Live Sound Processor
The DigIO allows up to twelve (12) digital sources to interface with a SymNet system. DigIO has onboard DSP and can act as a stand alone device as well as digital I/O expansion for a larger system. It can be used in home theater installations for speaker processing and to interface with digital mixing consoles in live sound for speaker processing or outboard EQ, dynamics and mixing/routing.

Additionally, DigIO offers an Ethernet interface if it is the master (first) device in a Ring of SymNet hardware. To simplify integration it features sample rate conversion on each input pair so digital equipment can be connected without syncing their digital clocks. And it can act as the master sync generator for a digital system via it’s Word Clock output operating at 48 kHz. If DigIO is the system clock master, sample rate conversion can be bypassed.

What cables are required to connect to ARCs?

A single standard straight-through CAT-5/6 cable will provide power and data to an ARC from the host DSP.  The daisy-chain to subsequent ARCs also uses CAT-5/6.

Legacy DSPs that pre-date the ARC Port (RJ-45) communicate to ARCs with a twisted-pair (A, B, Ground) for RS-485 data.  In this scenario a local external transformer provides up to 24VDC to the ARC.

How do I set the IP address of a SymNet Express unit?

Establish serial communication.

Edit menu > Site Ethernet Preferences.

Click on the Ring you wish to configure.

Click Edit Unit Settings.

Enable IP control, then enter the appropriate IP information and click Write Settings to Unit.  Or, Read Settings from Unit.  This dialog syncs the IP information between software and hardware.

 

What is video blackburst?

Blackburst is an analog video signal that contains sync information (frame rate) but no picture information. It serves the same function as Word Clock, but for video devices. It serves as a timing reference for VTRs and non-linear editors so that they can achieve frame-accurate locks during edits and transfers.

What are the most common external control commands for 3rd party controllers?

CS – Controller set.  Generally use for buttons.

CC – Controller change.  Generally use for faders.

LP – Load preset.

Examples:

CS <controller number><controller position><cr>

CC <controller number><1 for increment or 0 for decrement><amount><cr>

LP 1

Can I purchase a replacement power supply for my 6000/6100 factory direct?

Yes.  Have the unit serial number handy and contact support@symetrix.co or call +1 425 778 7728.

How many SymNet units can I connect together with SymLink?

There can be a maximum of 16 SymNet hardware units in a SymLink ring. This includes the 8×8 DSP, 8in DSP, 8out DSP, CobraLink, BreakIn12, Breakout12, and DigIO 12×12 DSP.

Is CobraNet TCP/IP routable?

No.  CobraNet is delivered via a 100Mbit Fast Ethernet switched network.

What are the ADAT sync connecters for on the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?

These connectors allow sending and receiving ADAT-specific information between daisy-chained ADAT machines or other hardware capable of sending or receiving ADAT Sync. The ADAT sync cable carries machine control, Word Clock, and timecode signals. These connectors, or the MIDI connectors, may be used for controlling the 8824. The only signal in the ADAT sync connection that matters to the 8824 is the machine control signal.

Note: If you are using the 8824 with the Alesis PCR card, the 8824 must be the first device connected after the PCR card. Doing so ensures that the 8824 can always receive commands (ADAT machines do not always pass ADAT Sync information through themselves.)

Where can I find a Flow Chart for the 571 SPL Computer?

Why does my 6000/6100 have audible artifacts while building delay?

Change or adjust the delay algorithm and/or delay ratio.  Find the algorithm and delay ratio that is the most appropriate for the program material.  For more information reference the unit’s User’s Guide.

Where can I find a Data Sheet for the 303 Interface Amplifier (Bi-directional) or 305 Distribution Amplifier (1x4)?

Why do the outputs of the 460 Presentation Audio Mixer sometimes mute between program changes?

It may be that in the case of the transitions that don’t mute, certain parameters of the presets are not far apart and in the case of the ones that do mute there are some fairly diverse settings between the two presets. The muting is by design with the intention of avoiding nasty pops or clicks that might otherwise result.

Where do I set the analog I/O levels of the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter to match my setup?

This can be accomplished using the provided 8824 Configuration application via MIDI System Exclusive messages.

The analog I/O level sliders of the 8824Config app provide gain control in 1dB increments from -96dB to +31dB for each of the 8 analog inputs or outputs. With the input gain set to -8dB, a +4dBu input translates to approximately 20dbFS (i.e. 20dB digital headroom). With the input gain set to +4dB, a -10dBV input translates to approximately -20dbFS (again, 20dB of digital headroom). Similarly, with the output gain set to +1dB, a -20dBFS input translates to approximately +4dBu into 600 ohms. With the output gain set to -11dB, a -20dBFS input translates to approximately -10dBV. In both of these cases, the actual headroom before clipping depends on the inputs of the mixer, power amplifier, etc, that the 8824 is driving.

The 371 SPL Computer's output is always too loud.

Try re-calibrating making sure that music/page is playing continuously during the calibration process at its normal or normal to high level. Check levels in Set MIN Limit. Check if the level is set too high in the Gain:Sense Ratio. Check in calibration if the maximum limit in Adjust to Maximum is set too high.

Is SymLink compatible with CobraNet?

Not directly. The similarity between SymLink and CobraNet is that they both use CAT5 cable and handle 64 channels of audio. In all other ways they are dissimilar and incompatible. However, by adding a SymNet CobraLink hardware module to a SymNet ring you can send to CobraNet and receive from CobraNet up to 32 channels of audio in each direction.

What is Superclock?

Superclock is a format used exclusively by Digidesign in their ProTools series of software and hardware. It is a clock reference that is 256 times the sampling rate. In theory this makes the clock more accurate because there are so many more pulses in the data stream. When interfacing with a ProTools system, make sure the output of the clock generator is set to Superclock. When incorporating regular Word Clock devices along with a ProTools system, it is necessary to support both formats simultaneously. The Lucid GENx6 will only do one at a time, but can be locked together with another GENx6. The GENx6-96 and SSG192 can support both formats simultaneously.

How do I hook up multiple 304s if I need more than 4 headphone channels?

Simply use the “thru” jacks to feed to the additional 304(s). This connecter is also convenient to patch headphones into an existing audio chain, for example: the signal going to a power amplifier could be routed to the input of the 304, the 304’s “thru” output signal would go to the amplifier, thus the audio feeds both the amplifier and the headphones.

How do I control SymNet Designer's Speaker Management modules with SmaartLive?

Can the GENx6 / GENx6-96 output Word Clock and Superclock simultaneously?

The GENx6 can only be set to output one or the other on all of its outputs. However, the outputs on the GENx6-96 can be switched individually to output one or the other.

Is it possible to get more than three levels of priority paging on the Zone Mix 760?

Absolutely!
How-to: More than three levels of paging with the Zone Mix 760
Within the offices of Symetrix, we often joke that our all-encompassing banner should actually read ‘Over-engineered by Symetrix’. We take great pride in the design of our products, so much so, that we often subconsciously overdo things — just a touch. It’s all for the better in the end, reinforcing our commitment to produce extremely high value, robust and affordable products for audio professionals.

As we’ve come to find out, the Zone Mix 760 is no exception. It is advertised as having three levels of paging plus emergency page and background music. However, it is possible to get four, and even five, levels of paging if you do not require the emergency page and/or wish to forego background music in a zone.

For up to four levels of priority paging plus one BGM (background music) source, you can use the Program 1 and Program 2 inputs for each zone as the lowest two paging levels (lowest of all is the BGM).

1. For a given zone, assign your BGM as the source for Program 1.
2. Select your lowest priority page mic as the source for Program 2.
3. Adjust the Ducker Threshold, Depth and Hold as necessary.
4. Set Page mics 2-4 as the sources for Page Stations 1-3.
5. Set the Page Station Priority to Low, Med and High, respectively, for Page Stations 1-3.
6. That’s it!

It is also possible to get five levels of paging. If you forego BGM in a zone, you can use the Program 1 source as your fifth paging source (lowest priority). Note that an external microphone preamplifier, such as the Symetrix 302 Dual Microphone Preamplifier, is required in order to connect microphones to the Audio Media inputs of the Zone Mix 760.

But why stop there? You can expand even further on this configuration because the Symetrix 302 is a dual microphone preamplifier, why not use that 2nd channel to feed the next Audio Media input on the 760 so you can have a unique lowest level paging source for another zone?

What exactly is Word Clock?

Word Clock is the timing reference that keeps the sampling rate constant. If, for example, we were recording at CD quality which means the A/D converter has to take 44,100 measurements of the incoming sound wave every second. If the clock isn’t as stable as it should be, then some seconds will have 44,100 samples while others might have more or less. The end result is a less than perfect digital representation of the wave. The clock frequency is the same value as the sampling rate.

Will phantom power damage my non-condenser microphones?

Generally no, some older ribbon microphones are somewhat susceptible, but it’s always a safe bet to disable phantom power when not needed.

What is the factory reset for the 6000/6100?

What is the maximum recommended length of a SymLink cable?

10 meters is the longest recommended cable length. In our lab, we have successfully used longer cables, up to 25 meters, but we only test and guarantee functionality at 10 meters. Additionally, the cables must be shielded to guarantee performance in environments susceptible to EMI and or RFI interference.

What is the maximum recommended length of an RS-232 cable?

Typically, 50 feet is the maximum length for reliable communications over RS-232. Some laptop PC’s use the low power, low emission RS-562 instead of RS-232. With RS-562 your cable run will be much shorter than with RS-232. You can use a low cost RS-232 buffer/repeater amplifier to extend both RS-232 and RS-562 maximum cable lengths. There are many manufacturers of these types of products. Here are links to a few US sources:

What is the communications turn-around delay on the 322 DSP Engine?

1ms at a baud rate of 38400.

Can SymLink busses be re-used to accommodate higher channel counts?

Yes, this can get confusing so it shouldn’t be attempted until users are familiar with the SymLink architecture. SymLink is a circular bus. The transmit port from one unit is connected to the receive port of the next unit using standard CAT5 cabling. You can send unique audio on this cable between any 2 units in a SymNet ring by using the “Send” object in SymNet Designer software. Every time you drop a “Send” object into a design, you have the ability to send new audio on the bus. Thus, audio can be received in a DSP unit caring a set of signals and then transmit a whole new set of signals “on the same” bus to the next device in the Ring. You must be aware of the order that SymNet devices are connected together. Please see Tech Notes for more detail concerning the re-use of SymLink busses.

How does ESE TC-89 time code work with the 6100 Broadcast Audio Delay?

The station or studio must be equipped with an ESE TC-89 master clock generator. The real time output of the master clock generator is connected to the 6100’s TIME CODE IN connector. The 6100 reads the incoming time code and adds to it the current amount of delay time. The time in delay (TID) is displayed on the 6100’s front panel LCD and also appears as time code at the 6100’s rear panel TIME CODE OUT connector that can be fed to a dedicated ESE clock for display of TID.

What do I do if I have a buzz or hum in the output of the 460 Presentation Audio Mixer?

1. Check input connector wiring.
2. Check output connector wiring.
3. If the hum or buzz is present in inputs 3 or 4, try connecting the chassis of the source equipment to the chassis of the 460. 4. Check for a ground loop problem. Inspect related systems equipment grounding to see that all system components are on the same AC ground.

Clicks, pops and/or pink noise on the analog outputs of the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?

This could be caused by a couple of scenarios:

A) If the 8824 is configured for the analogue outputs to get their source signal from the ADAT (optical) digital inputs and no signal is present the ADAT chip can act erratically and produce noise and digital garbage.

B) If the 8824 is configured for the analogue outputs to get their source signal from the ADAT (optical) digital inputs and the ADAT is turned off. Always power up ADATs and/or external clocks connected to the ADA 8824 first then power up the 8824 last.

What is the difference between the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter and the ADA8824 (Sonic) 24-bit Eight Channel A/D-D/A Converter for Sonic Solutions?

Where is the best placement for the 371 SPL Computer sensing microphone?

Ultimately the sensing microphone should be placed so that it’s picking up as much of the ambient noise as possible and as little of the speaker program as possible. The sensing microphone needs to “hear” the ambient sound within the controlled space. It is vital that you place the microphone where it primarily picks up a majority of noise rather than the paging or music that is going through the system. Do not locate the sensing microphone near a localized noise source that is not typical of the ambient noise level of the controlled zone, for example, the noise from a large machine of some sort, or maybe a kids play area, or a video game. If you do this the 371 will think that the zone is noisier than it really is.

The updated Designer 9.0 example design files and super-modules did not install with SymNet Designer 9.0 or higher.

If you are installing the full release version 9.0 but had a beta version previously installed, you must first completely uninstall the beta version for the new example files to appear.

If the example design files and super-modules do not appear after uninstalling the beta version and installing the full release, it may be necessary to manually delete the SND 9.0 beta registry section (HKEY_CURRENT_USERSoftwareSymetrixSymNet Designer 9.0) as well as the SymNet Designer 9.0 folder (My DocumentsSymNet Designer 9.0).

Then re-install SymNet Designer 9.0 and the new example files will appear.

How do I set up the 420 Stereo Power Amplifier in mono bridge?

To prevent inadvertent setting, the bridged-mono mode switch is located inside of the 420. To set or reset the switch, use the following procedure:

1. Disconnect the 420 from the AC power source.

2. Remove the top cover.

3. Locate the switch, which is situated near the input connectors.

4. Depress the switch plunger to select mono-bridge mode so that the plunger remains IN. For stereo mode, the switch plunger should be OUT.

5. Replace the top cover and all fasteners previously removed.

In mono-bridge mode, use the CHANNEL 1 INPUT, and connect the speaker across the two plus (+) output terminals. The channel 1 plus output terminal is the in-phase or non-inverting output connection. Connect it to the plus side of the speaker. Only the CHANNEL 1 GAIN control is functional. If you connect a pair of headphones to the front panel STEREO HEADPHONES jack, they will receive out-of-phase signals not harmful to anything (except phase or polarity fanatics).

In mono-bridge mode, the 420 delivers 40 watts into an 8 Ohm load. The minimum load impedance is 8 Ohms.

How does the 371 SPL Computer know the difference between the paging / music and ambient noise?

During the calibration procedure the 371 uses AmbiSense technology to calculates the percentage of the sense signal that is picked up from the paging and/or music that is going through the sound system. AmbiSense allows music or page pickup without any ill effects on its operation, up to about a 50:50 mix of music/page to ambient. In an extreme case where the sense microphone picks up 100% music/ page (0% ambient noise), AmbiSense will not be able to extract enough information to use for gain control.Basically this is how it works:

During the first stage of calibration, the 371 measures and calculates an averaged value of both the program material, and of the signal picked up by the sense microphone. Then during the second step of calibration, after the installer manually increases the program loudness, another set of readings are taken and averaged. Now, we have four numbers:

1. Average sense signal during quiet room

2. Average sense signal during loud(er) music

3. Average program level during first calibration step

4. Average program level during second calibration step

From these numbers (and other sneaky means) we can then calculate a good estimate of what percentage of the sense signal is due to the pickup of program audio, and therefore what percentage of the sense signal is likely to reflect the actual ambient noise.

How do I use third party RS-232 control using an ARC-2 or ARC-2i?

The ARC-2 and ARC-2i are versatile remote controllers that can hold up to twenty-four (24) total menu items and can easily be programmed to manage anything from gain, preset triggering, source selection, room combining and more.

Many installations require channel control on an external device, such as a television or satellite receiver.

Below are the easy step-by-step instructions to add this specific ARC-2 programming to your SymNet site file.  To begin, you will need to download the following link to the files containing the ARC-2 Channel Up/Down Super-Module, as well as the ARC-2 Programming.

http://www.symetrixaudio.com/kb/channel_up-down_arc2.zip

Importing the ARC-2 Programming:

1)     Open the Controller Manager

2)     On the right side, bottom half, under File click “Import…”

3)     Use the drop down, select the Ring the ARC-2 will physically connect to

4)     Browse to the folder containing download files, highlight “channel_up_down_arc2” and click “Open”

5)     Expand the RS-485 network to verify that the “TV / SAT Channel Controls” ARC-2 remote was successfully imported

6)     Edit ARC-2 RS-485 address to match your hardware (default is 0)

Importing the Super-Module:

1)     Open your site file, navigate to the design view (signal path).

2)     Tools->Super-module Manager, click the “Import” button

3)     Browse to the folder containing download files, highlight “channel_Up_DownARC2_supermod” and click “Open”

4)     Now in the Toolkit, expand “Super-modules”

5)     Drag the “channel_Up_DownARC2_supermod” into your design

6)     Click the red triangle in upper right corner of super-module for a description of adjustable controls and parameters

7)     Open super-module control screen, make parameter adjustments if needed

8)     Turn “On” 232 String Output (be sure to add RS-232 string for up and down command) and/or Open Collector Output to trigger channel attenuation from the ARC-2/2i

9)     “Download Entire Site File to SymNet” and to the RS-485 network devices.

After completing these easy steps, the ARC-2 or ARC-2i will control the channels of the third party device.

What is the maximum recommended length of an RS-485 cable?

4000 feet is the longest recommended cable length.

Why do I need a clock generator?

All digital audio gear requires some kind of timing reference in order to accurately maintain the sample rate. Because of this, every piece of digital gear has an internal clock. When digital communications are desired between devices, allowing each subsequent unit to control its own clock can and will result in degraded audio performance. This can be heard as “smearing” of the audio, loss of accuracy in the high end, degraded stereo imaging, and even clicks & pops. Controlling all of the sample clocks from one master timing reference eliminates jitter (timing irregularities) and assures the integrity of the sample rate, yielding better sounding audio.

How do I reset the 372 SPL Computer to the factory default settings?

After a lightning strike, flood, nuclear blast, or other catastrophic disturbance, the 372 may become inoperative if the data stored in its EPROM memory has been corrupted. The 372 can be returned to its factory default state by performing a master reset. To do this:

1. Unplug AC power

2. Press and hold in the EXIT and CAL buttons.

3. Reconnect AC power.

4. Let go of the EXIT and CAL buttons.

Now the LCD screen will display “EEPROM defaults restored” followed by the software version number. After doing this, all previous setup and calibration data will have been lost and must be re-entered as if it were a brand-new installation.

I can not ‘Go On-line’ with my Symetrix 780 after successfully completing the software’s Connection Wizard.

Why is my 302 so distorted?

Check the level of the input signal on the 302’s LED display. Is the CLIP light on all the time? If so, reduce the incoming signal level by turning the INPUT level counterclockwise. Is the incoming signal already distorted? Make sure that your microphone is not broken, and that the mic is not distorting, sometimes vocalists get a little too close to the mic causing its capsule and/or internal electronics to distort. Most studio condensers have switchable -10dB and -20dB pads to reduce the level from the capsule before it goes to the electronics, these are almost always needed with drum over-heads and high hats.

Why is the MUSIC/PAGE ERROR LED flashing at the end of my calibration of the 571 SPL Computer?

During calibration, the 571 requires continuous paging or music signal at its HOUSE PAGE, MUSIC IN or PAGE MIC inputs, if the PAGE/MUSIC switch on the rear of the 571 is in the “MUSIC” position. If the PAGE/MUSIC switch is in the “PAGE” position, calibration of the 571 requires continuous paging signal at either the HOUSE PAGE input or the PAGE MIC input. If the MUSIC/PAGE ERROR LED flashes, it means that the calibration was unsuccessful, because there was not enough signal present at the appropriate input(s).

Check the position of the MUSIC/PAGE switch. If it is in the “MUSIC” position, check that paging or music signals are being generated continuously and that they are at an appropriate level, i.e. line level (0dB) for the HOUSE PAGE or MUSIC IN inputs, and mic level (-40dB) for the PAGE MIC input. Make sure that these signals are actually reaching the desired 571 input (check your cables).

If the MUSIC/PAGE switch is in the “PAGE” position, check that paging signals are being generated continuously and that they are at an appropriated level, i.e. line level (0dB) for the HOUSE PAGE input, and mic level (-40dB) for the PAGE MIC input. Make sure that you are sending continuous signal to one of the page inputs, not the music input, and make sure that these signals are actually reaching the desired 571 input (check your cables).

If you are using the PAGE MIC input, check that the PAGE MIC trimpot has been turned clockwise. If this trimpot is turned part of the way to the full clockwise position, and the MUSIC/PAGE ERROR LED flashes when you attempt a calibration, try turning the PAGE MIC trimpot completely clockwise.

Why does the SENSE INPUT ERROR LED continue to flash at the end of the 571 SPL Computer calibration process?

The SENSE INPUT ERROR LED flashes at the end of a calibration attempt to indicate that the 571 is not receiving ambient level information on either the SENSE MIC 1 or SENSE MIC 2 inputs. If this happens, your calibration attempt was unsuccessful. Make sure that the SENSE 1 trimpot and the SENSE 2 trimpot(if used) are turned clockwise. If this trimpot is turned part of the way to the full clockwise position, and the SENSE INPUT ERROR LED flashes when you attempt a calibration, try turning the SENSE 1 AND SENSE 2 trimpots completely clockwise.

Check your mic cables, and make sure that a sense mic is actually plugged in to each sense mic cable. If your sense mics have ON/OFF switches, make sure that these are in the “ON” position. Current revision 571’s have phantom power on all mic inputs, but 571’s manufactured prior to early 1996 do not have phantom power, so you will need external power supplies for condenser mics used with pre-1996 571’s. Do not use an unbalanced mic with the 571. These mics usually short XLR pin 3 (“RING” on a 1/4 ” connector) to ground. If you connected one of these to a mic input on a current revision 571, you would be shorting the phantom power supply to ground. Also, an unbalanced mic line is far more likely than a balanced line to pick up noise, RF, etc. You can check your sense mic and mic cable by unplugging the cable from the 571’s SENSE MIC 1 or SENSE MIC 2 input, plugging the cable into a mic pre-amp, and listening to the output of the pre-amp with headphones. Be sure to reconnect the sense mic cable to the 571 afterwards!

You can also view the SENSE MIC inputs using the built-in factory test for the 571. To get into test mode, hold in the 571’s MODE switch for about 10 seconds, until the far left GAIN (dB) LED begins to flash. You are now in “Sense View” mode, and the GAIN (dB) LED’s will indicate the level of the ambient signal being picked up by the sense mics. If no LED’s light in this mode, try turning the Sense Mictrimpots completely clockwise. To return to “Operate” mode, power down the 571 and turn it back on.

If 8 channels of Dante audio are sent from one Edge Frame, does that mean that the second frame in the system now has only 56 channels of Dante left to transmit on, similar to how SymLink shared 64 channels amongst the entire ring?

Each Edge unit uses a Brooklyn II card which gives each Edge unit 64×64 discreet Dante inputs and outputs. This is not a shared number between units, as a total of 1024 channels can live on a Gigabit network at one time, such as in the case that 16 Edge frames are all transmitting 64 unique channels of Dante.

How do I exit delay for traffic reports and remotes on the 610?

Live traffic reports and commercial remotes require off-air monitoring and cueing. If the station broadcasts in delay, the reporter will hear his cue 7.5 seconds late which will result in 7.5 seconds of dead-air. In radio, 7.5 seconds of dead-air is a capital offense. There are operational procedures which will prevent the problem.

When using the full-dump mode: During delayed programs which include live traffic reports or news reports, the on-air talent must instantly return to real time for the live remote. This requires that the 610 be operated in the full-dump mode; all 7.5 seconds of delay must dump when the DUMP button is pushed. This procedure will not work properly when the 610 is in the two-stage dump mode.

Shortly before the live report the board operator must put the Symetrix 610 in the EXIT mode. The 610 begins backing down to real time. Next, the air talent gives the traffic reporter his standard verbal cue and stops talking. Immediately switch the studio monitors to off-air monitoring. When the verbal cue for the traffic reporter is heard, the board operator pushes the DUMP button on the 610. The station is now on-air at real time for the traffic report. At the end of the report the board operator should push the START button and the 610 will begin building back the 7.5 second delay.

1. Before the live report, put the 610 in the EXIT mode.
2. Give the remote talent their normal verbal cue.
3. Switch the studio to off-air monitoring.
4. When the verbal cue is heard on the air, push the DUMP button. (This puts the station on-air in real time.)
5. At the end of the live report, push the START button.
6. Switch the studio monitors back to “board output.”

When using the half-dump mode: During delayed programs which include live traffic reports or news reports, the on-air talent must instantly return to real time for the live remote. This method operates in either the full-dump or half-dump mode. You must provide the operator with the remote BYPASS function in the form of a SPST switch wired between pins 13 and 14 of the remote connector J8. (See your 610 User’s Manual.)

Shortly before the live report the air talent gives the traffic reporter his standard verbal cue and stops talking. Immediately switch the studio monitors to off-air monitoring. When the verbal cue for the traffic reporter is heard, the board operator pushes the remote BYPASS/OPERATE button. This forces the 610 into the BYPASS mode and the station is on-air in real time for the traffic report.

At the end of the report the board operator should push the remote BYPASS/OPERATE button and then the START button and the 610 will begin building back the 7.5 second delay.

1. While still in delay, give the remote talent their normal verbal cues.
2. Switch the studio to off-air monitoring.
3. When the verbal cue is heard on the air, push the remote BYPASS/OPERATE button. (This puts the station on-air in real time.)
4. At the end of the live report, push the BYPASS/OPERATE button and then the START button.
5. Switch the studio monitors back to “board output.”

Why doesn't the 421m AGC-Leveler or 422 Stereo AGC-Leveler work when I test them on my bench with a sine wave or pink noise?

The units will not attempt leveling action on a sine wave or pink noise because they do not recognize a sine wave or pink noise as true audio. To test the units, you must use a real-world audio source, such as music or speech.

What is the battery for on the SymNet 8x8 DSP motherboard?

There is indeed a battery on the DSP motherboard. Its only function is to keep the real time system clock running when power is disconnected from the SymNet hardware. FYI – the system clock drives the Event Scheduler – the feature that allows you to create a timed roster of preset and control output changes.

What can I do if the 572 SPL Computer does not accurately adjust the system level as ambient noise changes?

1. Repeat the calibration procedure. Make sure that you calibrate at a time when the ambient noise level is at a minimum, and check that you have set the MIN and MAX controls to give you the desired level adjustment range.

2. Disconnect the speakers from the system and, using a microphone preamplifier connected to the speaker(s), listen in headphones to what the 572 “hears” when it is sensing. Listen for any noises, such as air conditioning noise, that could falsely trigger a gain change. Listen for any hum or buzz. Make the necessary adjustments to correct any problems that you discover (reposition sensing speaker, fix or re-route wiring, etc.).

3. If you are using horn speakers, you may be overloading the sense input of the 572. Try disconnecting the amplifier and horn speakers from the FROM AMP and TO SPEAKER CONNECTIONS of the 572. Now connect the LINE OUTPUT of the 572 to the amplifier input, and connect the amplifier output to the speaker inputs. Then, use a single 8-ohm, paper cone speaker as your “sensing speaker”, connecting it to the FROM SPEAKER connection on the 572.

Will the ADA8824 (Sonic) 24-bit Eight Channel A/D-D/A Converter for Sonic Solutions work as a stand alone converter?

No, the ADA8824 (Sonic) 24-bit Eight Channel A/D-D/A Converter for Sonic Solutions is specifically designed to interface with Sonic Solutions SonicStudioTM.

How do I hook up a 302 to my computer?

If your computer has a sound card with line level inputs (NOT microphone level!!!), use the TRS line output jack connecting the tip as (+) and the sleeve as the common or ground. However, it is recommended to have a computer audio card or interface with professional +4 dBu balanced line level inputs.

Why am I missing the bottom of my SymNet Designer control screen?

SymNet Designer is configured to work with displays that have 1024×768 resolution of greater. If your computer is running 800×600, then some controls and status indicators will be outside the display area of your monitor. You may be able to change your display resolution via the Windows Control Panel.

Why can't I get the 421m AGC-Leveler or 422 Stereo AGC-Leveler to do much leveling action?

You may have the RATIO control set too low. Try turning it up to around 4:1.

What is the power output of the 304 Headphone Amplifier?

Approximately 200mW at 60 ohms or 21dBm at 600 ohms.

Will the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter work with ProTools?

Yes. While Digidesign encourages its customers to use their own proprietary hardware it is possible to make digital audio transfers to and from ProTools using industry standard AES or ADAT (lightpipe) connections. If you are a ProTools user and have a Digi 888(24) interface you can bypass the converters in the 888(24) and connect to a Lucid ADA8824 (ADAT) or other external converter via the 888(24)’s AES inputs and outputs. If you have a Digi ADAT Bridge you can make direct digital connections to the Lucid ADA8824 (ADAT) via the lightpipe connectors on each device. Note: Older versions of the Digidesign ADAT Bridge only support 20-bit audio transfers. The newer ADAT Bridges are 24-bit and are what we recommend to work with the Lucid 8824 (ADAT). The ADA8824 (ADAT) also makes a great front end for the Digi001 and Digi002 via their ADAT Lightpipe connections.

Where can I find a Data Sheet for the 301 Low Distortion Compressor / Limiter?

Should Symetrix hardware have an extra rack space above and below it in the equipment rack?

Anecdotal evidence suggests a longer life-span of Symetrix hardware that is separated by at least one additional space in the equipment rack.  This is in addition to following the guidelines for maximum recommended ambient operation temperature.  See unit’s Quick Start Guide for information.

Why can't I monitor the analog outputs when feeding signal to the analog input on the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?

The analog outputs from the 8824 are fed by either the Optical or AES digital inputs, there are no connections between the A/D and D/A. If you just want to get signal looping through the unit for test purposes, attach an ADAT loopback cable (connect the ADAT OUT to ADAT IN directly with a single cable).

When is shielded CAT5/6 cable recommended?

SymLink bus and Dante network connections.  In addition to EMI and RF protection the shield also helps ensure the same ground potential between units.  Under normal controlled conditions it’s unlikely that using unshielded CAT5 will have negative results.

Audinate recommends using only CAT6 cable for Dante as it can support larger bandwidth than CAT5.

What steps are necessary in order to run Dante DSP with Dante set to “Redundant Mode”?

All Dante devices ship with Dante in the default “Switched mode”. This allows units to be daisy chained, eliminating the need for 3rd party networking hardware. When in “Switched mode” if the Dante hardware is setup physically in a Redundant network configuration, traffic from the Primary Dante port will flow out the Secondary Dante port, and the Dante traffic from the Secondary Dante port will flow out the Primary Dante port. This creates a data feedback loop on the Dante network that will crash the Dante cards in the SymNet units. SymNet units with only Dante connections, such as the xIn 12 and the xOut 12, may become unresponsive until they are power cycled and the redundant Dante network switch is turned off or the redundant ports are unplugged from the secondary Dante network.

As such, to set the system to run Dante in “Redundant mode”, first go online with the system with only the Primary Dante port connected to the network or network switch. Alternatively, if the Secondary Dante ports are already connected to a network switch, turn off the secondary Dante network switch/switches. If the Secondary network switch cannot be turned off, or both Primary and Secondary Dante use the same network or switch, then unplug all Secondary Dante ports.

Next, go to Composer>Dante Flow Manager and hit the “Configure Dante…” button and set the Secondary Dante jack to “Redundant Network”. Then push the file to the SymNet system.

Verify via a DSP’s front panel display that the Dante mode now reads “Redundant”. When it does indicate “Redundant” mode is active, plug in the secondary Dante ports or turn on the secondary Dante network switch/switches.

What are the default IP settings of network ready SymNet devices?

Express and CobraLink do not have default IP settings. IP settings are user specified and are static.

Solus hardware will obtain an address through DHCP. If no address has been assigned (either by the user or by DHCP) a default 169.254 IP base is used.

Tip: The last two octets of the IP address can be determined by converting the last two groups of numbers of the unit’s MAC address from hex to decimal.

In a multi-box system, what unit do I connect the host computer to?

For normal use you will always connect to a Master unit.

TI-101 Telephone Interface has hum in the caller audio

The signal to noise performance of the TI-101 can be improved 15 dB by relocating the power transformer. If your power transformer is mounted on the bottom of the chassis its field induces hum into the caller output transformer. Remounting the power transformer to the side of the chassis corrects the problem. The details are in the TI-101 Service Notes.

ARC Power Calculator

An ARC’s power requirements vary depending on the voltage supplied to it. For example, an ARC-2e at 24V DC uses approximately 55 mA, while at 7V DC it uses approximately 170 mA maximum. As the voltage varies from 24 to 7 VDC, the current requirement increases accordingly. ARCs can be daisy-chained and fed power over this daisy-chain from an ARC-PSe or other device. However, as the length of the cable increases, so does the resistive line loss, which lowers the voltage available at each subsequent ARC. The actual power drain on each output from the powering device can vary substantially depending on the number of ARCs and the distance each of them is separated by. In order to assist with system design, Symetrix has available a Microsoft Excel spreadsheet that can help a system designer determine power requirements based upon cable length, number of ARCs and the power supply to be used.

Clicks and pops when using external clock with the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?

Determine which external clock (AES1 thru 3, S/PDIF, WORD, ADAT optical) is causing clicks. Its entirely possible the ADA8824 is working correctly but that the clicks are occurring somewhere else in his system, or that there is a sync issue with the system (master/slave stuff, etc). There can be only one master device in a clocking system, all others must slave to it either directly or indirectly. Additionally, when using AES input, ensure that all AES sources are in sync (referencing the same clock source themselves).

When must you calibrate the 371 SPL Computer?

Calibrate at a quiet-to-average time in the controlled space. It helps if you have an estimate (sound pressure level) of the maximum desired level. Check the sound system to see that it is capable of delivering that level.

Why do I hear distortion when the 610 Broadcast Audio Delay is activated?

A level increase of this magnitude will increase the amount of compression applied by the limiter by 6 dB. This change will be noticed by anyone sensitive to the station’s sound. Distortion will become evident if the input circuit of the limiter runs out of headroom and clips. Clipping may also occur in other devices downstream from the audio processor in your audio chain (distribution amps, STL transmitters).

On-air talent will invariably accuse the 610 for any degradation in audio quality because the problem will make itself evident when they push the START button on the 610 and begin building delay.

One solution is to convert the input of the device plugged into the 610’s output to a bridging (high impedance) input. If this is done, the console output will switch between two bridging inputs when the 610 cycles between bypass and operate. There will be no significant change in loading to the console output.

Most modern equipment is built with electronically balanced inputs. Transformer inputs are virtually never used anymore. If an input presents a 600-ohm load, it is most likely created by the addition of a 620-ohm resistor across the input circuit. Removal of this resistor may be all that is required to convert the input to a bridging input. Consult the manual, or call the manufacturer of your audio processor, for assistance.

Where can I download the software for the 6200 Digital Voice Processor?

Where can I find a Data Sheet for the 528E Voice Processor?

How long can the cables be connecting the 303 to my computer or CD player?

The unbalanced cables (those connected to the -10dBV equipment or RCA connectors) should be kept at 6 feet or less to minimize the noise and hum that may be induced. The balanced (+4dBu) cables can be ran hundreds of feet with very little induced hum and noise.

Where can I find a User's Guide for the SX-208 Stereo Compressor / Limiter?

How can the 302 improve recording quality?

The 302 is an ultra-clean two channel dual mono preamp for use in critical digital and analog recording situations. For optimum sonic performance and lowest possible noise, route the 302’s output(s) directly into the tape machine or recording device’s line input(s) as opposed to going through a mixing console. This approach eliminates unnecessary noise and coloration, also most built-in mic pre amps on the small portable recorders and computer sound cards are rather noisy, using the line input and a good clean mic-pre will almost always result in a cleaner sounding recording.

Where can I find Schematics for the 303 Interface Amplifier (Bi-directional)?

Will the optional card slot on the Radius AEC support all SymNet I/O card options?

Absolutely. All SymNet I/O card are 100% compatible with Radius AEC and Edge.

Why is the signal from my 303 Interface Amplifier (Bi-directional) noisy?

Check the input signal. The 303’s unbalanced inputs are designed to run at -10dBV nominal, and the 303’s balanced inputs are designed to run at +4dBu nominal. Make sure that you are feeding a line level (not mic level) signal to the 303 at the appropriate nominal level. Check gain settings on downstream equipment. The system gain structure should be such that the 303 operates at or near unity gain. Is the input signal already noisy?

Where can I find a Flow Chart for the 501 Peak-RMS Compressor / Limiter?

After upgrading to SymNet Designer from an earlier version, my control screens are behaving strangely.

There is a remote chance that the control screen or SymVue panel created in an earlier version of Designer contains control data that no longer matches the current module.  (Pre Designer 8.0 and older increases this risk.)

First, replace the control in the control screen with a new one from the existing module.  If this does not solve the problem, it may be necessary to replace the original module from which the control was copied.

What is a SymNet Ring, Address, Master and Slave?

A Ring is a group of hardware linked together via the SymLink bus.  A single Express unit is also a Ring within it’s self.

An Address is the unique identifier of a device in a SymLink Ring.

A Master is the Address 1 unit.  Express units are always Address 1 and are therefor a Ring Master as no other devices “slave” to an Express.

A Slave is a non-Master unit in a SymLink Ring.

Does the Radius 12x8 work with the other Dante enabled SymNet hardware?

Yes, but it doesn’t stop there.  All Dante enabled SymNet hardware, including the Radius 12×8, is compatible with any Dante hardware from any manufacturer.

Where can I find Schematics for the 307 Dual Isolation Transformer?

What do I do if I'm experiencing noise (hiss) from the 460 Presentation Audio Mixer?

1. Check input signal levels and level control settings.
2. Check to see if the source signal is noisy.
3. Check if there is too much noise downstream by using the output level controls of the 460 at Mute.

What are dual-mono modules?

Dual mono modules are two independent mono modules that are physically grouped together.   The major benefit is DSP efficiency as they use only about half as much DSP as two separate equivalent mono modules.  Note, dual mono modules are not available in the 8×8 DSP.

How does the Automation Control Interface work on the 6000 Broadcast Audio Delay and 6100 Broadcast Audio Delay?

The 6000 and 6100 have four internal relays that may be independently used to control station automation events. The relay closures (outputs) are triggered by input closures that can be either manual (a momentary switch closure) or electrical (TTL logic low). When an input closure takes place the audio entering the delay at that moment is ‘tagged’. When the tagged audio reaches the output of the delay its corresponding relay closes for a time equal to the length of the input closure.

What kind of cable do I use to hook up the Analog Control Inputs?

Standard two-conductor shielded twisted pair.

What do the DIP switches on the back of hardware do?

DIP switches determine the Ring and Address of the unit, whether the unit is a Master or a Slave, and what the baud rate is for host computer serial communication.

Where can I find a Data Sheet for the 610 Broadcast Audio Delay?

Why does my 610 system level change when I switch between Operate and Bypass?

A few users are surprised with large gain increases when they install the 610 into their audio chain. Here’s why.

The 610 uses a balanced, bridging input. It does not present a 600-ohm load to the output of the device which drives the 610’s input. In other words, your console output is not loaded by 600 ohms when the 610 is in the circuit and operating.

When the 610 is in the bypass mode, a relay connects the output connectors to the input connectors. This is a “hardwire” bypass, a copper path between input and output. This means that when the 610 is in the bypass mode, the console output sees the load of the input circuit of the device connected to the 610’s output connectors. Your console output connects directly to the input of your audio processor anytime that the 610 is not in delay.

If the audio processor input presents a 600-ohm load to the console output, the 610 will remove the load to the console output when it goes on-line. Because the console output is no longer connected to a 600-ohm load, its output signal may rise as much as 6 dB, depending upon the output circuitry.

This level increase will pass through the 610. The input of the audio processor will receive a signal which is 7 dB hotter than when the 610 is in the bypass mode. This is because of the 6 dB gain change caused by removal of the 600-ohm load, plus a 1 dB gain increase inside the 610. We use a heavy duty output driver in the 610. It is able to supply the same output level to either a bridging input (high impedance) or a 600-ohm load. The 610’s output does not drop when it is loaded with 600 ohms. The output drivers of some equipment are not this robust.

Can I sync to the AES inputs on the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?

The 8824’s A/Ds can be synchronized to the first 3 AES3 inputs, and also the S/PDIF input. Simply connect a valid AES3 or S/PDIF signal to the desired input (24kHz-48kHz only), and select that input as the A/D Sync Source, using the dip switch (local mode) or configuration application (remote mode).

I just added up all the % numbers in the DSP modules I put in my design, and it doesn’t quite match what the DSP resource meter reads. Why?

The DSP resource percentage figure located on each Module is rounded to the nearest integer value. The DSP resource total meter (located below the toolkit) tallies the actual, non-rounded figure. In addition, hidden routing modules are added to move audio between DSPs. These routing modules take a small amount of DSP resources.

What is the minimum load impedance the 420 Stereo Power Amplifier can safely handle?

The minimum load impedance of the 420 is 4 Ohms in stereo or dual-mono mode and 8 Ohms in mono-bridged mode.

Where can I find a Data Sheet for the 302 Dual Microphone Preamplifier?

Why does my 6000/6100 show ‘64P’ on the display and is not operating?

The bypass is engaged and ‘BYP’ is commonly mistaken for ‘64P’ on the display.

How do I lengthen priority release time on the 450 Dual Zone Priority Mixer?

Increase the value of the following resistors for the appropriate priority:

Priority 1: R229 and R230
Priority 2: R321 and R322
Priority 3: R141 and R142

The amount of time increases in direct proportion to the amount that you increase the value of R229 and R230. For example, if you double the value of Priority 1’s R229 and R230 (from 536K to 1Meg – O.K., its approximately double), then the length of time for the muting circuit to release and allow signal from the lower priorities will also double (from 2-3 seconds to 4-6 seconds).

Can I upload the Designer Site File from SymNet hardware into my laptop/desktop computer?

Yes. SymNet’s archiving function, which is part of the Full Site Download (F4) operation, allows you to store and extract SymNet Site Files to and from the rack mounted hardware. Provided that hardware security is not enabled or you know the Supervisor password if it is, you can connect to the hardware with any version of SymNet Designer and open the Upgrade Firmware dialog in order to determine which version of SymNet Designer you should use to communicate with the hardware. Once that is known, you can upload the Site File from SymNet using the proper version of SymNet Designer.

Will phantom power damage my non-condenser microphones?

Generally no, some older ribbon microphones are somewhat susceptible, but it’s always a safe bet to disable phantom power when not needed.

Why is my 302 so noisy?

If you’re going directly to line level inputs of a recording device as suggested chances are it’s coming from the microphone’s internal capsule pre-amp, some of the older microphones sought after for their character and warmth especially the tube versions have rather noisy electronics. Check input signal level. The input signal may be too low. If so, boost the incoming signal (if possible) or move your mic closer to the signal source. Obviously drum over-heads will need a lot less gain than an acoustic guitar.

Where can I find a schematic for the 528E Voice Processor?

In order to choose the correct schematic for your particular 528E unit, you will need to derive both the unit revision and the manufactured date from the serial number of the unit. This number always begins with the number “80”, and will be on a sticker on the bottom of the 528E.

Depending on the age of the unit, this number could appear in a couple of possible formats. This is a key detail, as schematics are not available for current serial numbers.

Current Serial Numbers:
Current units have serial numbers in the following format:

120V version: 80-4528EANA0912176
230V version:  80-4528EAEU0912176

The presence of a hyphen and either “NA” or “EU” in the serial number are both indicators that this is a current serial number.

If you need repairs for current serial numbers, please contact Symetrix Support at support@symetrix.co.

Old Serial Numbers:
Older units have serial numbers that appear without a hyphen, and will have the manufacture date printed on the sticker.

Example: 800528E0B0854

The unit revision is shown by the two characters following the model number (800528E). In the example above, the “0B” points to a Revision B unit.

The manufacture date for older units can appear in a couple of different date formats. One may see a more typical date format (e.g. 09/19/05), or perhaps a format as shown in the picture below. In this example, the year is first – so the manufacture date is May 7, 2008.

How do the SSG192 High Definition Studio Sync Generator and Lucid Distribution boxes fit into a modern studio setup?

There are a variety of scenarios where the combination of one or more of these products will improve or even stabilize the performance of a modern digital recording/editing system. Some examples are:

Simple digital audio setup – GENx6 will generate word or superclock through its 6 outputs to synchronize multiple generic or Digidesign devices (either/or, not both simultaneously).

Post production – the SSG 192 functions as the master timing reference for a video editing suite where digital audio needs to be integrated into and resolved to the video. It delivers video sync to VTRs and non-linear editors, word clock to digital audio devices, and superclock to Digidesign products. It can also reference to incoming blackburst from video gear.

Audio recording – the SSG delivers word clock and superclock to the appropriate digital audio devices. It can be configured via internal jumpers to provide 3 word and 3 superclock outputs simultaneously. The most direct and reliable solution for a scenario that includes Pro Tools and other digital audio gear in the same system. A alternative solution would be to use 2 GENx6 units sync’d to each other with one generating word clock and the other generating superclock. Less expensive than a single SSG.

Multiroom facility – the SSG provides audio sync via AES11 output (audio equivalent of blackburst) that is stable down a long cable run (200+ feet). CLKx6 or GENx6 can receive the AES sync and distribute it as word clock or superclock to the local rack. AESx4 can be placed in between the SSG and distribution boxes to create up to 4 streams to address 4 separate rooms. SSG has 2 AES outputs for 8 possible sync streams from 2 AESx4 units, to 8 CLKx6 or GENx6, to 48 peripheral devices.

I have placed the SymNet CobraNet firmware upgrade files in the specified location, but Disco still can not see them?

If Disco does not find the CobraNet firmware file you require, you will need to exit Disco and then edit the “CNDisco.exe.Config” file.

This file will typically be located at: C:Cirrus LogicCobraNet Discovery.

Find “CNDisco.exe.Config” then open it using Notepad.

Locate the line:

“<Advanced Feature = 0>”

Change the value to “1”

Then Save-As.  Save as type: All Files.  Save directly over the top of the original: CNDisco.exe.Config.  Do not let it save as a text document, which requires retyping the name “CNDisco.exe.Config”.

Launch Disco to try again.  If done properly you will see additional options allowing you to “show all firmware versions.”

How much latency is there in a SymNet SymLink system?

Converter delay: Approximately 850 microseconds for the AD, and 624 microseconds for the DA.
One DSP core: Maximum delay through any given 8×8 DSP core is approximately 240 microseconds, though typically it will be much lower. The max delay through the DSP core of an 8in or 8out is 120 microseconds.

SymLink: Approximately 80 microseconds for an audio signal to travel, via SymLink, from the DSP core of one 8×8 to the unit immediately downstream. If there are any units in between, add an additional 80 microseconds for each SymNet DSP, 20 microseconds for each CobraLink and 20 microseconds for each BreakIn12 and BreakOut12.

In summary: The typical delay for a signal that goes into an analog input on an 8×8, and exits from an analog output on the same 8×8 is usually around 1.5 milliseconds.

Do Edge Frames, when Dante is daisy chained, need to be looped back into a ring configuration like SymLink?

Edge units are daisy chained, and not a ring configuration. In an Edge system the last unit should not be connected directly to the first unit, rather just daisy chaining them creates the entire Dante network, as each Dante port is truly its own Gigabit network switch.

Why is the Automation Control Interface and the TC-89 Clock Reader such a powerful combination of tools on the 6100 Broadcast Audio Delay?

As an example of how they are used together assume that a local talk show switches to syndicated network news every day at 12:00:00 (noon). Assume one of the 6100’s Automation Control Outputs controls a router that switches the air signal from the local studio audio to the network audio. A manual push button is wired to the 6100’s corresponding automation control relay. The air talent views the ESE clock displaying TID (time in delay which is real time plus the amount of delay added by the 6100). At 11:59:00 (TID) the air talent ends his sentence and presses the designated push button. The audio built up in the 6100 continues to play out until 11:59:00 (real time) at which time the relay closes and switches from local audio to network audio. The powerful combination of 6100, TC-89 master clock generator and TC-89 time clock reader allow the air talent to make a perfect transition from delay audio to real time without the need for manual time calculations.

How do I convert the line level output of the 628 Digital Voice Processor to mic level?

Unplug all connectors from the 628 and remove it from the rack.
Remove the top cover. Don’t forget the two allen head screws on the front panel.
Locate the ANALOG OUTPUT XLR connectors on the rear panel.
Depending upon the vintage of your 628, you’ll find one of two options:
A) 2 jumper sets of 2 each (J6, J7 and J10, J11) or,
B) 2 jumper sets of 3 each (J4, J5, J7 and J9, J10, J12).

If your 628 matches option A, then move both jumpers next to the output connector which you want to convert to microphone level rearward to the jumper pins closest to the XLR connector.

If your 628 matches option B, find the 3 jumpers nearest the XLR connector that you want to convert to microphone level. Move the left jumper (J4 or J10) so that it connects the two jumper pins furthest to the right. Move the right jumper (J7 or J12) so that it connects the two jumper pins furthest to the left. Now insure that the remaining jumper (J5 or J9) is in a rearward position that connects the two jumper pins nearest the XLR connector.

Replace the top cover and all retaining screws.
Reinstall the 628 in your rack.
Connect the power and audio cables

How do I place AGC ahead of the Automixer DSP module Designer?

AGC and Automixing
It is often desirable to place dynamic processors such as Compressors and Automatic Gain Control (AGC) ahead of the Automixer DSP module however; this presents a small technical issue. Automixers determine which channels are active by discriminating between the differences in each channel’s signal level. Compressors or AGCs effectively minimize the differences between each channel’s signal level. This tech tip illustrates the recommended use of dynamic processing after an Automixer module.

Wiring and Module Layout
This example requires a single AGC module attached to the Mix out of the Automixer. The AGC Ctrl (control) output wires to the VCA Control input. (The VCA module is located in the Mixer and Matrixes section of the SymNet Designer toolkit). The VCA audio inputs are connected to the channel outputs of the Automixer. The VCA audio output is wired to a Matrix module to create mix-minus feeds for zones. Prior to the AGC is an Expander/Gate module that is used to remove the noise floor of the channel outputs as necessary.

Example 1 Image

VCA Max Gain Compensation
There is one more consideration; the VCA has a Max Gain parameter. Different dynamic processors send out different control signal levels so the Max Gain parameter is used to compensate for any differences. When using the AGC module in this fashion, the Max Gain needs to be at +36 dB.

Example 2 Image

More information on this subject is located in the SymNet help file. Within the Dynamics section, there is a heading titled “Creating Multi-channel Dynamics Modules” which discusses the VCA output settings for various Dynamic processors.

The intent of this design is to flatten out the mics so that soft and loud voices come out the speakers at the same volume. Many will argue that dynamics should be wired prior to the Automixer. However, this design serves to conserve DSP resources as well as allow the Automixer to do its job as designed. Give it try; you may be surprised with the results.

The Radius AEC is a 12x8, do all 12 inputs have AEC?

No, the Radius AEC has 8 mic/line AEC inputs and 4 line level inputs.  For 12 channels of AEC in a Radius AEC the optional card slot will support the 4 Channel AEC Input Card.

Why are there no LEDs illuminated under LOCK on the front panel of my GENx6-96?

These LEDs are only active when the GENx6 (or GENx6-96) is set to receive a clock input from an external source (AES, Word Clock or Superclock). With the SOURCE switch in the down position EXT and the EXTERNAL switch set to the desired source (AES, Word Clock or Superclock), the LEDs will indicate that the GENx6 (GENx6-96) has locked to an external clock input. When the outputs are internally generated none of the LOCK LEDs are lit.

528E Voice Processor settings tutorial.

Get the Perfect Settings for Your 528E Voice Processor
The 528E is one of the most complete and versatile Voice Processors on the market today. The ability to tune the timbre and quality of your voice is essential in creating the kind of quality production and/or on-air product that your listeners demand and deserve. Getting the perfect settings to work for your specific application will take a little practice and experimentation. So, to get you up and running as quickly as possible here’s a brief tutorial to get the most out of your 528E Voice Processor.

We strongly encourage you to read the 528E Voice Processor User’s Guide because it’s filled with a lot of useful information about getting the most out of your microphone and your voice. If you can’t find yours anywhere around the station, feel free to download a copy.

Initial Settings

With all hardware connections made, and the 528E powered on (LED displays activity), set the controls and switches on the front panel as shown.

528E starting settings

Red marked X indicates that button is pushed IN.

Mic Preamp Gain

Push out the DE-ESS, EXP/COMP, and the EQ buttons into bypass mode.

Set the MIC GAIN control so that the CLIP LED should almost never illuminate.

De-esser Settings

To reduce the level of sibilant sounds (S and T sounds)

Set the THRESHOLD control to show about 12 dB of gain reduction.

Adjust the FREQUENCY control for maximum sibilance reduction.

Decrease the THRESHOLD setting until you reduce the sibilance to a tolerable level.

Downward Expander Settings

To reduce room noise and/or mouth noises

Set the THRESHOLD control to allow low-level speech sounds to pass while still blocking the room sound.

Compressor Settings

To vary the amount of gain reduction

3 to 6 dB is sufficient unless you are using a low compression ratio (below 2:1), or you want a special effect. Choose a ratio suited to the task at hand:

Low level ratios and low thresholds for unobtrusive level control.

Medium ratios for overall level control and consistency.

High ratios (>8:1) for limiting or ‘in-your-face’ sorts of sounds.

Equalizer Settings

The initial settings work well with male voices.

For women

Increase low-EQ range to 200 or 300 Hz.

Increase mid-EQ range to 3 to 5 kHz.

If you are using a mic that exhibits proximity effect when close-micing

Decrease (cut) the bass (low) response somewhat. 3 to 6 dB should be fine (don’t do this if you want a big, ballsy sound).

Some mid-EQ helps make voices cut and seem loud.

High-EQ adds brightness and intimacy.

If you are using a mic that has no proximity effect when close-micing

Increase (boost) the bass response somewhat. 3 to 6 dB should do the job.

Some mid-EQ helps make voices cut and seem loud.

High-EQ adds brightness and intimacy.

Output Settings

For many applications, the output GAIN control at 0 dB works fine.

Push in the buttons for DE-ESSER, EXP/COMP, and EQ.

If you increased the EQ, then you may need to increase GAIN.

If you increased compression, you may need to increase GAIN.

Choose a setting that gives you enough signal downstream, yet keeps the CLIP LED from illuminating.

The output CLIP LED monitors both the EQ and the output stage. Large amounts of boost and /or high level signals can cause CLIP indications. If this occurs, lower the signal level by adjusting the GAIN control.

It is also possible for the output stage to clip if a processor, inserted using the output stage access jacks, is contributing gain to the overall signal path. In this case, either lower the gain of the insert processor or decrease the setting of the GAIN control.

Is the 302 distorting when the clip light is on?

Yes and no, the CLIP LED lights when the signal reaches 3dB below clipping. This LED should never be on solidly. It is usually all right if the CLIP LED flashes occasionally, on peaks in the program material. If you see the CLIP LED light, monitor your final signal destination to be sure that you are not creating distortion by running audio levels that are too hot.

Where can I download archived versions of Composer software?

Archived versions of all final public releases of Composer software are listed in the table below. The software runs on a Windows PC and is used to configure, design, and control Composer-based products. For new designs we highly recommend using the latest version of Composer, however archived major release versions can be found below for legacy compatibility and/or troubleshooting requirements. All firmware files are included as part of the downloaded Composer software package. The Composer firmware versions and Dante Kernels listed below are to help in cross-referencing the firmware running on the installed DSP(s) with the corresponding version of Composer that should be downloaded.

To communicate with Symetrix hardware from a given version of Composer, it may be necessary to upgrade (or downgrade) firmware in each hardware device. This can be done directly from the Composer application and only takes a few minutes per device. Firmware upgrade is done from the Composer Hardware menu.

How do you downgrade a SymNet Designer system?

Going backwards: Restoring to previous versions of Firmware, in other words downgrading. When traveling back in time and reverting to a previous version of SymNet Designer, there are a few gotchas to be aware of:

First… Turn off All Amplifiers! You’re upgrading (or in this case, downgrading) an entire audio system! Murphy’s Law always applies – anything can happen and will happen. Do not turn on the amps until you are sure all software changes/reconfigurations are finished and successful. Then, it is suggested that you turn the amps down and ease them up. An ounce of precaution is worth a pound of cure. Also, in later versions of SymNet Designer (version 3.5 or higher), the volume will ramp up after a Site file is downloaded according to a time setting in the Preferences dialog box located in the File pull-down menu. Set this for a long ramp up period. If there is distortion, feedback or unintended routing in the system, it will ramp up slowly and give you time to react. Consider yourself warned.

Next, you need to downgrade the system in reverse order. So, you must start with the highest numbered device address in a ring and work backwards in decending address order. If you change the Master unit to a previous version first (i.e. the first unit in a SymNet Ring), you will not be able to address the Slave units through the SymLink bus. If this happens, you have 2 options:
Change the Master unit back to the “more recent” version and then begin the firmware downgrade process again starting with the last unit.

Disconnect the SymLink connections from all units. Change the DIP switches on the back of the slave units to make them a master unit and change all their addresses to ID #1. Then, connect to the front panel of each unit individually and perform the upgrade (downgrade). Finally, reconfigure the DIP switches to their original settings, re-patch the SymLink bus and re-power the system.

Make sure you have an older version of the SymNet Site File! This is important, as when you double click on a SymNet file, Windows will launch the Site File with the last version of SymNet Designer software installed, not the older version, and your Site File will be loaded into it. If Auto Save is turned on (Go to the File pull-down menu and select Preferences to see the Auto Save Enable setting) in the newer version and it executes a Save, then you have essentially upgraded your Site File. Now it will not open in the earlier version. It is best to have a copy that is saved in the previous version that has not been opened in the newer version.

For more information on upgrading SymNet systems, see the ReadMe file that accompanies every software release.

No, the Edge frame is the only frame with redundant power options; however, all SymNet Dante enabled DSP hardware has redundant Dante and control ports.

Where can I find Schematics for the 104A Multi-line Telephone Interface?

What kind of cable do I need to use for digital audio over AES / EBU inputs and outputs?

All AES / EBU inputs and outputs need a 110 Ohm twisted pair AES / EBU cable. You should not / can not use a standard microphone cable for digital audio!

Why do the DSP delay modules in SymNet Designer require so little DSP resource?

The actual delay memory is a handled outside of the SHARC DSP chips – by fast synchronous DRAM chips that can be accessed extremely quickly by the DSP. This greatly reduces the ‘load’ on the DSP core.

My Integrator Series 760, 780 or 788 hardware is locking during boot-up.

If your Integrator Series 760, 780 or 788 hardware is locking during boot-up and you have a 3rd-party external controller connected (such as an AMX or Crestron), there is a possibility that the controller is sending commands before the DSP is fully booted, corrupting the boot process.

Power-cycle the Symetrix hardware, then delay all external controller commands at power-up approximately 15 seconds to ensure the DSP is fully booted before it receives any commands.

Units manufactured after August 2009 have a feature that will block uninitiated / unsolicited serial data from an external controller during boot up.  Also, units communicating to external controllers via UDP/IP (made before or after August 2009) are unaffected.

Any linear deviation in playback speed. The sample rate is affected because the playback is either sped up or slowed down. The applications are primarily for video and occur during format transfers either between PAL and NTSC, and/or film to video. The values are 4% and .1% and can be applied in a positive or negative direction. 4% is the difference between NTSC at 29.97 fps and PAL at 25 fps. The .1% value is often used during layback of audio to video.

How do I extend SymLink up to 200 feet?

SymLink is one of the fastest, easiest to use audio busses in the industry, but some integrators want to run SymLink cables longer than the maximum specified length of 10 meters. In the past it just wasn’t possible, but we are happy to announce that this is no longer the case — with a few stipulations.

First, let’s explore some background on SymLink. Put on your propeller caps for a quick cable lesson.

As you may know, SymLink uses standard STP (shielded twisted pair) CAT5 cable supporting up to 10 meters in length. Typical CAT5 cable, by design, has different twist lengths for each pair which means that each pair has a different physical length. This difference in length causes a signal delay difference from pair to pair which is known as skew. Excessive skew between the twisted pairs that carry data and the audio clock can cause a great deal of grief.

Fear not! Your friendly Symetrix engineers have found an alternative solution brought to us from the land of video, a cable that can increase the maximum SymLink cable length from 10 meters to 61 meters, or 200 feet worth of SymLink. Read on for the details…

We’ve tested a new low-skew cable manufactured by Belden, model number 7987. Designed for long distance video runs, Belden 7987 has extremely low skew. It is even available in Plenum-rated and Riser-rated versions. The Belden part number for the plenum-rated version is 7987P while the riser-rated version is 7987R.

To attain SymLink distances of 200 feet, three conditions must be met:

1. You need a cable with sufficiently low skew.

2. Since the Belden 7987 is an unshielded cable, particular attention needs to be paid to the ground potential between SymNet devices.*

3. Lastly, the quality of the RJ-45 connections must be perfect. Sloppy connections or slightly bent pins will reduce the achievable length.

*In our testing of a worst case scenario (one device floating and the other grounded), we measured a ~50 VAC (RMS, measured with multi-meter) mismatch between the devices. However, as soon as a SymLink cable was connected between them, even an unshielded cable, the ground difference was reduced to a few volts. While the SymLink transmitter/receiver chips have some built-in protection to prevent any damage, the long term effects of a large voltage differential between units is unknown at this time.

As always, your mileage may vary. While this revelation in cable technology has proven itself in our lab environment, we can not possibly test all of the unknowns one may encounter in a real-world installation. A little care to ensure that all devices are indeed grounded and all SymLink RJ-45 connections are tight should provide great reward.

Where can I download archived versions of the SymNet Designer software?

Archived versions of SymNet Designer (found below) run on a Windows PC and are used to configure, design and control the SymNet units. For new designs we highly recommend using the latest version of SymNet Designer, however archived major release versions can be found below for legacy compatibility and/or troubleshooting requirements.

To communicate with SymNet hardware from a given version of SymNet Designer, it may be necessary to upgrade (or downgrade) firmware in each SymNet hardware device. This can be done directly from the SymNet Designer application and only takes a few minutes per device. Firmware upgrade is done from the SymNet Designer Hardware menu.

How can I see how much ambient level is being picked up by the speakers when the 572 Flow Chart is in "SENSE" mode?

Set OPTIONS switch “B” to the “UP” position. The 572’s GAIN (dB) LED’s will now display the level of ambient noise that is being picked up by the sensing speakers.

NOTE: This interrupts normal operation of the 572. Return OPTIONS switch “B” to the “DOWN” position, to restore normal operation of the 572.

What happens if a SymLink ring is interrupted due to a bad, or unplugged cable?

All units in the ring will continue to function but audio and control signals will not be transmitted across the gap nor will any control information be transferred “downstream” of the gap.

What kind of DSP is used in SymNet Express?

Express units use Analog Devices SHARC ADSP-21161 DSPs running at approx. 100MHz. These DSPs also feature the Single Instruction Multiple Data (SIMD) architecture which can effectively double their processing power for certain modules (e.g. stereo EQs). Each Express unit has two of these DSPs. The two DSPs can deliver a theoretical maximum combined total of 1180 MFLOPS (Mega Floating Point Operations Per Second).

What type of switch is required for a CobraNet network?

Use a quality switch capable of 100Mbps Ethernet traffic.

In a multi-box system, what unit do I connect the 3rd party controller to?

Serial: For normal use you will always connect to a Master unit.

Ethernet: Connect to the same network that connects all devices’ Ethernet ports.

Why are my Master and Slave 372 SPL Computer units not sensing at the same time?

When the 372 SPL Computer does a sense event it fades the audio down from its current gain setting to -80dB at X amount of time per dB, then opens a relay and takes a series of samples via the installed speaker(s). If multiple 372s/zones are synched together, the master unit first fades down it’s audio then activates its relay, simultaneously sending a trigger event signal via the EXT.RELAY pin to the slaved unit’s TRIGGER pin inputs, because the master first fades its audio then sends the trigger signal, the master and slave(s) are slightly out of sync. Furthermore, if the slaves are at different gain settings, the fade times may be far enough apart that the slaved relays operate at slightly different times. In other words, a 372 with it’s gain at +5dB will take longer to fade down the audio and open it’s relay than a unit set at 0dB.

This was corrected in version 2.09 of the firmware. To update the firmware to version, contact Symetrix Technical Support.

Are SymNet Designer site files backwards compatible?

No.  A site file created later than the version of Designer you are running will not open.  The latest version of Designer will open any site file.

Do SymNet modules need to have a wire connecting them to pass audio in Designer or is there another way to route an audio signal within the system?

SymNet Designer DSP modules do need to have a wire connecting them to pass audio signals. Control modules are the only modules that in some circumstances can be assigned internal via a “virtual” path instead of graphically wired together.

Where can I find a Flow Chart for the 306 Preamp / Ducker?

What is the I/O headroom on the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?

In both local modes (+4) and remote (+4/-10), the default headroom is set to 20dB. Therefore, setting the unit to +4 means the maximum input is +24dBu, and that the maximum output level is +24dBu (+/- 0.5dB). By using the variable I/O) gain control from the remote mode configuration applications (PC or Mac), the user can alter the unit’s input and output headroom.

Can I copy/paste DSP module settings in Designer?

Yes. Use the mouse right-click to save and load DSP module settings to and from your disk-based ‘Settings File’. The ‘Settings File’ is a library that you can use to store EQ, Compressor, Crossover, etc. setups and recall them at will for later use. Alternatively, you can copy a whole DSP module within a configuration or between configurations. From the Design View, just click on the module, choose copy, and then paste it where you want the new module to go.

What are the jitter specifications for the GENx6 / GENx6-96?

20ps rms, 50ps peak jitter; 10ppm typical, 50ppm max drift.

Where can I find a User's Guide for the 425 Dual Compressor / Limiter / Expander?

What is the ARC-PS?

The ARC-PS is an 8 port expansion hub for data, power and ARC audio.  The ARC-PS is supported by all host DSPs.  Note, some DSPs may require a special cable.  Contact support@symetrix.co for more information.

Can my Symetrix-manufactured unit normally powered by the PS-3 be battery powered for remote use?

No, the only option would be to use a 12VDC to 117VAC inverter with the supplied PS-3 inline power supply.

There is an orange light flashing inside my Lucid 88192. Is something wrong with my unit?

The flashing light indicates that the converter is properly booted and running normally. If the light ceases to flash, this would indicate a problem.

Where can I find a Data Sheet for the 308 VCA Volume Control / Loudness EQ?

The 371 SPL Computer seems to have no effect.

Check the ratio setting for Gain:Sense Ratio. At 0.5:1, the gain changes are very subtle. Choose a larger value for more change. Check the bar graph in Sense to see if the sense level is always the same, because then the gain will always be the same. Make sure the unit is not in HISTORY or BYPASS mode.

Where can I find mechanical drawings for the ARC-2 front panel so that I can have custom panels made?

Versions for punched metal and machined materials are provided below. A third drawing for the display window is also provided. Using these drawings, contractors may build their own custom ARC-2 front panels to match decor or specific needs.

Where can I find a Data Sheet for the S/PDIFx7 S/PDIF Distribution Amplifier?

Is the THI-101 a VOIP device or work with VOIP systems?

The THI-101 works with any phone by connecting to the headset connection whether the phone line is POTS or VOIP.

Is the SSG192 a time code (LTC, VITC, etc.) generator?

No. A time code generator creates a linear stream of addresses that can be interpreted by a time code reader (stand-alone, embedding into picture, or incorporated into a device) as an absolute location. It is used to synchronize transports when lockup of multiple machines is desired. The SSG192 does not support this function or synchronize in this context.

Why is the signal from my 303 Interface Amplifier (Bi-directional) distorted?

Check the input signal. Is it too hot, or is it already distorted? Check the output loading. It should be above or equal to 600 ohms. Is the input of the device following the 303 clipping? Is something else clipping?

What if I order an Edge or Radius AEC Frame but do not fill up the card slots?

Filler panels will reside in the empty slots.

I have an older 528E without the internal mic/line switch. How can I change the XLR line output to microphone level?

Tools Required:

#2 Phillips-head screwdriver

Top Cover Removal:

Ensure that the 528E is disconnected from the AC power source.

Remove two 6-32 x 1/2 inch screws from the top panel and two 6-32 x 1/2 inch screws from each side of the chassis.

Lift the top cover free of the chassis.

Changing The XLR Output Level:

The 528E ships from Symetrix with the XLR output configured for a line level output. If you must have a microphone level output, the following steps lead you through the process of switching the XLR line level output to microphone level (or back to line level).

Remove the top cover according to the steps outlined above.

Locate the XLR output connector.

Find the “Output Level” solder pads J17 and J18 directly behind the XLR connector.

Fill the space between the J17 pads with solder.

Fill the space between the J18 pads with solder.

Locate the two circuit board traces next to J18 marked by the word “Cut”.

Cut these two traces with a small, sharp knife.

Replace the top cover.

Reinstall the 528E into your setup.

Where is the Sound Control Panel in Mac OS 8.x?

With system 8.0 and up the Sound Control Panel can be found in the Apple Extras folder, rather than the Control Panels folder.

What do I do if the remote volume control on the 460 Presentation Audio Mixer is not working?

1. Check CTL Destination setting in Main menu.

2. Check CTL Offset and Mult in Serial Control Setup and Options menu.

How do I reset my Integrator Series 722, 760, 780 or 788 to the factory default settings?

The factory reset button is located just to the left of the device’s Ethernet port. Using a pen or a paper clip, depress this button and continue to hold it down. While doing this, unplug the device, wait about 10 seconds and then plug the device back in… continue to keep the reset button depressed until the device has gone through a “light show,” where all of the LEDs on the device briefly light in sequence.

Once the light show stops (approximately 15 seconds), release the reset button. The device is now returned to  the state it was in when it arrived from the factory.

The main advantage of resetting the device to a factory default state is that it will re-enable DHCP (Dynamic Host Control Protocol) on the device, thereby automatically assigning a reliable and predictable IP address in the 169.x.x.x base.

What is the maximum sample rate for the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?

48 kHz.

How is data transmitted between multiple Express units?

Via Ethernet or serial.

Ethernet: TCP/IP.

Serial:  Serial data is bundled with CobraNet audio.

ARC-SWK Programming: How do I separating the LED logic from the buttons?

The ARC-SWK is a popular wall panel for SymNet systems. Symetrix has been involved in many designs where the LEDs for the ARC-SWK (or ARC-SW4) need to respond in a unique fashion in relation to the buttons they are associated with. In standard modes, the LEDs follow the buttons and will light green or red when the button is pressed or it can toggle on and off when the button is repeatedly pressed.

But what if you want to make the LEDs toggle between green and red? Or what about amber LED indication which can be achieved if the LED red and green state are triggered simultaneously? To achieve this, you have to be aware of a few things…

In the Controller Manager, create an ARC-SWK in the RS-485 Network.

Double-click the ARC-SWK in the menu tree to edit its settings and select the “Switches Tab”.

Fig 1: Controller Manager Window (under the Tools pull-down menu)

Select “Independent Switches” mode in the Switches tab.

Fig 2: Independent Switches Mode

Select “Manually Assign LEDs” in the “Switch LEDs” mode. Now the LED Number pull-down will be activated and you can select each LED for editing. The “Controller Number” assignments for the Green and the Red LEDs can now be set.

Fig 3: Manually Assign LED mode

The Next phase uses the RS-232/485 Output modules. These are located in the Control Modules menu in the SymNet Toolkit (F8 toggles the toolkit on and off).

Fig 4: RS-232/485 Output Module located in: Control Modules> Control Outputs> RS-232/485 Output module

Now let’s look at a design concept where 2 presets are toggled on and off with one button on an ARC wall panel. Below is the module design.
View Image

There is a button that would be linked to the button on the ARC SWK.

There are 2 preset trigger modules and an inverter.

The inverter module allows one preset to be triggered when the button is pressed/on and another when the button is pressed/off.

The RS-232 modules are then used to relay controller number information to the RS-485. Notice they are set to numbers 1 and 2.

These are the same setting as in Fig 3 which shows how the ARC needs to be configured.

Remember the ARC entire site file needs to be downloaded before it will work. The ARC network has a separate download.

How can I use a "DJ Tamer" in Designer?

Clever Use of Dynamic Side-chains Creates a “DJ Tamer” This tech tip is more of a featured application. The “DJ Tamer” linked below is no more than a clever use of the side-chain inputs on a few of the standard dynamics modules found in SymNet Designer.

The DJ Tamer works by tricking a DJ to stay within a predetermined gain range, allowing him/her to push their gain up to a certain point. After that point, his/her gain will be automatically attenuated. The DJ should then be able to figure out the point of maximum gain (allowed by the system installer) and remain there, thus saving your precious sound system from overload.

The Site File linked below contains text notes for setup. A Super-module which can be exported for use in other Site Files is also embedded within the Site File.

Can multiple 6000 or 6100 units be controlled by a remote (RC-6000) to dump, cough, start and exit at the same time?

Yes, although custom wiring is required. You would do this by wiring to the contact closure and ground pins on the back of both units in parallel, and then wiring the remote LED indicator pins from just one of the units. The units can not and will not be in perfect sync (start and exit build times), however, the dump, cough, start and exit functions will be triggered at the same time on both units from one remote.

Where can I find a Flow Chart for the 402 Dual Output Delay?

What gear works with a clock generator?

Many digital devices now support external clocking. Generally, if the unit has a digital output, it will probably have clock input and output connectors. The most common format uses a BNC type connector (tall, silver barrel on the chassis, twist-lock connector in the cable). This format calls for a special Word Clock cable. You’ll find this connection (external clock input) on digital consoles, DAT machines, CD-Rs, sound cards with digital I/O, processors, and of course, A/D converters.

My PC is unable to communicate with the 322 DSP Engine

1. Check your RS-232 serial cable. It should be a straight-through standard 232 cable.
2. Check the DIP switches on the back of the 322. For a single unit at address 1, only switch 1 should be up. All others should be down.
3. Make sure the 232 cable is firmly connected between your PC’s serial port and the 322’s front panel 232 input.
4. Power the unit on.
5. Open the 322 Designer software.
6. Under the File->Preferences menu, make sure you have the correct serial port selected. If you do not know which COM ports are available on your computer, check the Windows Device Manager.
7. Finally, press the Online button and choose DOWNLOAD design to units from CURRENT site file.
8. If that still doesn’t help, double check that the serial port on your PC is actually working correctly. Try to communicate with another unit of some kind. Try another serial port if you have one. Make sure that no other software is running that may be using the serial port. And finally, try another PC entirely.

Will the TI-101 Telephone Interface work with an electronic telephone system?

The design of the TI-101 limits its dependable use to standard central office lines. Installing an analog adapter or analog circuit card in the system might be a solution. It is your only choice if the telephone system digitizes the audio. Using this mode of operation, install the hybrid and a single line telephone on the analog extension. Answer incoming calls on the regular system and transfer them to the analog extension.

To assure that you get the right equipment, tell your phone installer that you want a fax machine on that extension. If a fax machine will operate on a line, a telephone hybrid will also. Your phone installer will not understand what you need if you talk to him about a “phone hybrid”. He will understand the requirements for a fax machine.

How do I monitor the source signal while recording with the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?

This is normally accomplished by the hardware/software connected to the AES or Light Pipe connections. For example with an ADAT connected to the optical in/out, the ADAT will make the connection between the A/D and D/A and determine if the analogue output signal(s) are derived from either the source (A/D) or from the tape.

How can I use the 420 Stereo Power Amplifier for a headphone amp?

The 420 is ideally suited to headphone distribution systems. There are two basic strategies involved in making a loud headphone system:

1. If you have low impedance phones, then you need high current capability to make them loud. This translates to a modest 8 Ohm power rating, like 20 watts.

2. If you have high impedance phones, then you need high voltage capability to make them loud. This translates to a moderate 8 Ohm power rating, like 100 watts

Why is there a high frequency roll-off while the 610 Broadcast Audio Delay builds delay?

While the 610 is building delay, the frequency response is down 1 dB at 6 kHz, 2 dB at 8 kHz and 3.5 dB at 10 kHz. Once the 610 builds its 7.5 second delay the frequency response is flat (within 1 dB) between 20 Hz and 14 kHz.

Can I plug a microphone directly into a SymNet 8x8DSP, 8 In, or BreakIn 12?

Yes. All SymNet 8×8 DSP, 8 In and BreakIn 12 units’ with analog audio inputs are equipped with software controlled mic/line inputs. In the 8×8 and 8in, digitally controlled precision analog attenuators are part of the analog input stages. Adjustments made to the input gain block in SymNet Designer actually trim the level of analog signal being sent to the A/D converter – allowing you to maximize the dynamic range performance of the SymNet hardware. On the BreakIn12, software controls the coarse gain levels of the mic preamp and fine trim is done with DSP modules in SymNet Designer.

Why does my AirTools 6200 Voice Processor sometimes have trouble staying connected via Ethernet for extended periods of time?

We are aware of a small problem with the 6200 Designer software that, under certain (though uncommon) circumstances, results in dropping offline when the 6200 hardware is connected via Ethernet.

The two scenarios under which we are able to duplicate this problem are:

Network saturation (for example, CobraNet traffic):
By sending a large volume data such as broadcast CobraNet audio (multicast bundles) onto the same subnet as the 6200 and PC, we were able to make the unit drop off-line within a few minutes.

Using a repeater hub and deliberately adding network traffic:
Using a hub, it is possible to flood the 10 Mbit Ethernet port on the 6200 with more data than it can handle. We found we could force it to drop offline by one of the following methods: copying a large file from a network server to the PC running 6200 Designer; or by opening a remote desktop connection to the PC running 6200 Desginer (sending data-intensive screen updates); and using Windows Update utility while starting a transfer.

Most Ethernet “hubs” today are actually switches. The difference between a repeater hub and a switch is that a repeater hub sends traffic received at one port out to all other ports, whereas a hub intelligently looks at who the packet is intended for and sends it out to only the appropriate port(s). This is important because with a repeater hub, it is possible to have a collision that subsequently requires a retry. This will not occur when using a switch. (It is actually quite difficult to buy a repeater hub today, since switches are a superior technology and are replacing hubs in most manufacturers’ product lines.)

Where can I find a SymNet SymVue site file for the Zone Mix 760?

This is a SymNet Designer file that contains pre-built control screens that will control the main parameters of a Zone Mix 760.  The IP address in the SymNet file must match the IP address of the 760.  Once the IP addresses are aligned, the screens must be exported out of SymNet Designer and then opened in SymVue software.

Why is the MUSIC/PAGE ERROR LED flashing at the end of my calibration of the 572 SPL Computer?

During calibration, the 572 requires continuous paging or music signal at its HOUSE or MUSIC Line Inputs or at the PAGE MIC input. If the MUSIC/PAGE ERROR LED flashes, it means that the calibration was unsuccessful, because there was not enough signal present at the input(s).

1. Make sure that OPTIONS dip switch “A” is in the “DOWN” position.
2. Check that paging or music signals are being generated continuously and that they are at an appropriate level, i.e. line level (0dB) for the HOUSE or MUSIC Line Inputs, and mic level (-40dB) for the PAGE MIC input.
3. Make sure that these signals are actually reaching the desired 572 input (check your cables).
4. If you are applying signal to the PAGE MIC input, check that the PAGE MIC trimpot has been turned clockwise. If this trimpot is turned only part of the way to the full clockwise position, and the MUSIC/PAGE ERROR LED flashes when you attempt a calibration, try turning the PAGE MIC trimpot completely clockwise.

What is Phantom Power?

Phantom power derives its name from its invisibility to audio signals, even though the microphone cable carries both phantom power (as direct current) and audio signals (as alternating current). Specifically, the term phantom power means a positive DC voltage sent to the microphone on both audio leads, through current-limiting resistors which also serve to isolate the audio leads from one another. The front panel phantom power button applies phantom power via pins 2 and 3 of the mic input XLR connectors.

2. Signal from the source(s) is getting to the 460.

3. The signal chain after the 460 is functioning.

4. Check if the LCD display is illuminated.

5. If signal is present, and the downstream system is operative, check the level settings at inputs and outputs to ensure that they are not muted or attenuated sufficiently to make the 460 appear to not be functioning.

Why does the 6200 keep "losing" its hardware settings after configuration?

There is a known bug in 6200 Designer where after configuring the Hardware Settings (found under the Unit menu in 6200 Designer) and then clicking the done button, the settings are not saved in the unit. The work around for this bug is quite simple: Click the Windows Close Box (the “X”) in the upper right hand corner of the dialog instead of clicking the “Done” button. This will write the hardware settings to the unit.

How does a 3rd party control system such as AMX or Crestron interface with the Integrator Series products?

Host control (via the Integrator Series software applications) is over Ethernet.

3rd-party control (AMX and Crestron type systems) may also interface over Ethernet, or by RS-232 on certain Integrator Series products (such as Zone Mix 760’s shipped after January 1, 2008) and the Automix Matrix 780.

The Integrator Series products use the same “RS-232” ASCII control protocol SymNet (as of Designer version 7.0) uses encapsulated into UDP packets. This is quickly becoming the preferred control method in the industry as it flattens out the control system into a true network. No more point-to-point comms, multiple serial cards, or distance limitations. The bonus here is, if the control system programmer is already familiar with SymNet, there is no learning curve!

The Control Protocol for the Integrator Series products can be downloaded here.

Crestron modules for the Zone Mix 760 are available here.

For additional reference, the SymNet Control Protocol can be found here.

Should Word Clock cables all be the same length? And what is the recommended maximum length?

In an ideal world, yes. You cable the system up with equal length cables to avoid any delays in getting the clock signal to the target devices. Using mismatched cables could potentially negate the benefits of setting up a central clock system.

Word Clock cables should be kept as short as possible, not to exceed 15 feet.

External equipment will not sync to the AES outputs of the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?

External equipment should have no problems syncing to the 8824 AES outputs – they are all phase aligned (unlike some equipment), and as long as they are receiving a good clock they will work. If not setup properly then it is possible they won’t work – i.e. if the 8824 AES outputs are set to get data (and hence clock) from the ADAT (optical) inputs, and there is no ADAT input, then its not going to work.

What is the maximum voltage recommended for the analog control inputs on a SymNet device?

The input stage of an analog control input of a SymNet device will clamp on an input exceeding +5.5V.  Anything above +5.5V will draw excessive current (the amount depending on the output resistance of the device supplying the current) and could possibly damage the input stage.  Keep analog control input current to below +5.5V.

Which PCI24 PCI Computer I/O Card driver do I use?

The PCI24 audio card needs a software interface or driver to communicate with your audio application. Applications such as Cubase VST use an ASIO interface in place of the Macintosh Sound Manager. ASIO (Audio Stream In/Out) is a VST software interface for input/output of digital audio via audio cards. Please refer to the documentation included with your digital audio software to determine the proper driver/software combination (i.e. ASIO, Sound Manager, etc.). Be sure to check the version of your application as some software developers are changing from the Sound Manager interface to ASIO. The following is a sample of Lucid drivers/extensions used with popular digital audio production applications. Go to the download area at the bottom of this section for a list of the latest available drivers.

How do I reset the 371 SPL Computer to the factory default settings?

After a lightning strike, flood, nuclear blast, or other catastrophic disturbance, the 371 may become inoperative if the data stored in its EEPROM memory has been corrupted. The 371 can be returned to its factory default state by performing a master reset. To do this:

1. Unplug AC power
2. Press and hold in the NEXT and EXIT buttons.
3. Reconnect AC power.
4. Let go of the NEXT and EXIT buttons.
5. Press and release EXIT three times.
6. Now the LCD screen will display “EEPROM defaults restored” followed by the software version number. After doing this, all previous setup and calibration data will have been lost and must be re-entered as if it were a brand-new installation.
