Edge Expansion Cards

4x I/O Expansion Card slots supports Analog In,
Analog Out, Digital In, Digital Out, AEC, USB, VoIP or
Analog Telco cards

Total Input/Output Flexibility. When a preconfigured DSP just won’t do, Edge provides four versatile option card slots enabling unique I/O configurations – aligning the hardware with the exact system requirements. Optional cards support analog and AES-3 digital I/O as well as special purpose interfaces including USB, AEC, VoIP, and analog telephone.

Dante™ in Our DNA.  Edge DSPs are equipped with an optional factory installed 128 (64×64) redundant Dante channels. The Dante protocol enables ultra-reliable multi-channel audio networking over IP. Together, Symetrix and Dante provide the fastest possible way to implement, control, and maintain a system of networked DSPs and accessories – including third party Dante-enabled microphones, loudspeakers, power amps, and mixing consoles. And an option without Dante provides even more accessible DSP pricing for standalone systems.

On-board 10/100 and Gigabit Switches.  Unique to Symetrix Radius and Edge DSPs, built in switches lower system cost, reduce or eliminate the need for peripheral switches, and increase system reliability.

Unlimited Programming Flexibility.  Edge is programmed using Composer – Symetrix’ award winning open-architecture CAD application. Unique to Composer is the ability to natively configure Symetrix and select third party Dante hardware – thereby eliminating the confusion of multiple or redundant software applications. Learn more about Composer here.

Control Made Easy.  Multiple control options include low-cost Symetrix ARC wall panels and an easy to generate SymVue Windows virtual GUI. The human readable Composer Control Protocol supports programming of third-party touch screens and control devices.

An Embedded Web Server for Status and Even More Control.  Edge’s embedded web server displays I/O levels, diagnostics data, and hosts ARC-WEB – a browser-based interface for smart phones, tablets, and computers.

Frequently Asked Questions

Edge DSP

  • How is the RS-232 port on Edge used?

    RS-232 is a standardized protocol for serial communication. Edge can talk to 3rd party controllers and devices on the RS-232 network using simple ASCII control strings.

  • Does Edge contain local GPIO or is a control accessory, such as the xControl needed?

    Yes, the Edge does have local GPIO so the xControl is not needed in most cases. The Edge frame has 8 analog control ports (8 pots or 16 switches) and 8 Logic Outputs.

  • 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. 

  • 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 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.

  • 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.

  • 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.

  • 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.

  • How does my 3rd party external controller talk to my Symetrix unit?

    Serial or Ethernet (UDP/IP)

    Note, the control protocol / command strings are the same regardless of the communication mode.

  • 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.

  • How much processing does an Edge frame contain?

    An Edge frame utilizes a 400Mhz SHARC processor for DSP.

  • Does a Edge frame have enough processing for to support a xIn 12 or xOut 12?

    Absolutely, the Edge has enough processing to support two xIO devices in most cases. In heavy laden DSP applications, it may be preferable to use only one xIO per Edge.

  • 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.

  • 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.

  • 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 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.


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

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

    LP 1

  • 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

  • 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.

  • 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.
