What is SymVue?

SymVue is a custom, stand-alone user control application for Composer-based DSPs. A SymVue panel is created from a Designer control screen and runs on any Windows compatible PC. SymVue connects to hardware via the hardware’s IP address and up to eight (software) instances of SymVue can run on each PC.

Where do I find the latest firmware for my DSP?

The latest firmware is always bundled with the latest software.  There is no need to manage the firmware independently.

Can I talk to Composer-based DSPs using HyperTerminal?

If the unit has RS-232 control, yes.  HyperTerminal can be used to simulate an external controller.

Default settings:

Baud: 38400

Data bits: 8

Parity: None

Stop bits: 1

Flow control: None

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

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.

Can I use a USB to serial adaptor to communicate to a Composer-based system with RS-232?

Yes.  Note, Belkin cables show mixed results.

What is the RS-485 network?

RS-485 is a standardized network for balanced digital multipoint communication.  In Composer-based hardware, only ARCs can use the RS-485 network.

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

4000 feet is the longest recommended cable length.

Where can I find an owner's manual for my Symetrix product?

All technical and operational instructions and documentation for current Symetrix products are contained within the Help menu of the Designer and/or Composer software. Simply click on the question-mark icon on the toolbar in Designer/Composer and search your topic.

Download the latest version of Designer or Composer at www.symetrix.co.

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.

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.

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.

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.

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

Standard two-conductor shielded twisted pair.

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.

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.

How do I know what COM port my USB to serial adapter is using?

See your PC’s Device Manager.

Right-click My Computer > Manage > System Tools > Device Manager > Ports (COM & LPT).

Is it possible to use the AEC in a Radius AEC to apply echo cancelling to a Dante enabled mic?

Yes, any source can be routed through the AEC algorithm using the AUX In module, this includes audio received from a Dante flow.

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.

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.

[/list]

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.

Composer Crestron Modules v.2.0

The v2.0 Crestron modules are compatible with SymNet Composer hardware including Edge, Radius 12×8, Radius AEC, Prism, Solus NX, xControl, SymNet 2 Line Telephone Interface Card.  Examples provided include Fader control, Button press, Increment and Decrement button, Preset Recall, Mute All, and Controller Receiver.

Note: Creston v2.0 modules where specifically designed to work with SymNet Composer hardware over RS-232 (baud rate 57600) or UDP/IP port 48631.  These modules can also be used for UDP/IP control with legacy SymNet hardware, Integrator Series, Jupiter Series, and Solus by simply changing the RS-232 buad rate to 38400 or the UDP/IP port to 48630.

2 Line Analog Telephony Interface Crestron Control Module v2

This program was created to demonstrate the capabilities of the SymNet 2 Line Analog Telephone Interface (ATI) card in the context of Crestron external control.
The user module and touch panel signals that comprise 95% of this program can be easily copied to other integration projects where the Symetrix ATI card will be used.
A Composer file has been created that has the controller numbers corresponding to this external control program. This allows the correct information to flow in both directions between the device and control system processor.

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.

What is the RS-232 network?

RS-232 is a standardized protocol for serial communication.  Some Symetrix devices talk to 3rd party controllers on an RS-232 network using simple ASCI control strings.

What pins are used on the serial cable?

2, 3, 5, straight-through.

How much processing and routing can be handled with my DSP?

Processing and routing capabilities vary greatly per design and hardware being used.  Each module block indicates its DSP usage.  Total usage is viewed in Designer or Composer below the Tool-kit on the bottom left of the screen.

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.

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.

Where can I find an Ethernet application with IP capable Symetrix products?

SymNet Remote Terminal is a UDP terminal test application for testing Ethernet-based control for Symetrix products.
