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.

Tech Tip: Selected Wire Audio and Real-time Monitoring via Host Computer Speakers

301 Schematics

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.

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.

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.

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.

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.

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.

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

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.)

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.

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.

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.

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.

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.

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-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?

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.

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

Tech Tip: Third Party Control

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.

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.

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.

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.

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.

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.

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.

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.

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.

4000 feet is the longest recommended cable length.

Tech Tip: Tips and Tricks for Successful AEC

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.

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.

No.

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.

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.

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.”

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.

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.

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.

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.

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.

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).

Tech Tip: Gain Structure Maximize Dynamic Range, Minimize the Noise Floor

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.

2x Quick Start Guide

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.

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.

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?

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.

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.

Tech Tip: 780 – Camera Following Through Logic Triggering

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.

Priority 2: R321 and R322

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).

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.

Tech Tip: Troubleshooting your Windows PC to Symetrix hardware connection

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.

This question has a three part answer since the digital signal path through a SymNet system has three different major components.

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.

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.

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.

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.

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.

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.

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.

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.

ARCs are extremely flexible and can be assigned virtually any real-time parameters depending on what host DSP it is controlling.  Generally ARCs are used for volumes, buttons, and presets.

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.

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.

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.

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).

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

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

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.

Composer Crestron Modules v.3.0

The v3.0 Crestron modules are compatible with Composer hardware including Edge, Radius 12×8 EX, Radius AEC, Prism, Solus NX, xControl, 2 Line Analog Telephone Interface Card, and the 2 Line VoIP Interface Card. The following control modules have been developed and will be available for use with the Crestron 2 and 3 series controllers:

• Volume Up/Down Control Module with User Limits
• Fader Set Control Module
• Button Push Module
• Preset Execution Module
• Controller Receiver Module
• Input / Output Selector Module
• VoIP Dialer Module and ATI Dialer Module
• Speed Dial Module / Speed Dial Store / Delete Phone Number / Name Module

The updated Crestron modules utilize command processor architecture to maximize efficiency and responsiveness. The command processor is responsible for all the data parsing to and from the Symetrix DSP which makes it more efficient for the individual control modules to operate. When the control ID’s match a particular control module, then the controller information is used and updated.

Note: Crestron v.3.0 modules were specifically designed to work with SymNet Composer hardware over RS-232 (baud rate 57600), TCP/IP or UDP/IP port 48631. These modules will not work with legacy SymNet hardware. If you have legacy SymNet hardware, please use the Crestron v.1.0 or 2.0 modules.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.)

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.

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.

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!

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 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.

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.
