Processing and Control for Professional AV Installations

Composer Series

Prism

Symetrix’s Prism open-architecture DSPs are the workhorse of any system and meet the needs of many
common applications. Available in a variety of common channel configuration and with both Dante and non-Dante options, there is a Prism perfect for your application, without spending on unneeded features.

Series Features

  • DSP Price / Performance Breakthrough
  • 4×4, 8×8, 12×12, and 16×16 models
  • Optional 128 Channel (64×64) Dante
  • DSP Processing Identical to Radius and Edge
  • Delay Memory Identical to Radius and Edge 

Flexible IO Combinations. The prism family scales from the smallest 4×4 to the largest 16×16, providing the perfect amount of class leading Symetrix quality IO for any installation.

Dante™ in Our DNA.  Prism DSPs are equipped with optional factory installed 128 (64×64) 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. Models without Dante provide even more accessible DSP pricing for smaller systems.

Scaling Up.  A Prism system’s analog input and output count may be increased using Symetrix Dante-enabled xIn 4, xIO 4×4, xOut 4, xIn 12, and xOut 12 analog I/O expanders.

Unlimited Programming Flexibility.  Prism 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.

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.  Prism’s embedded web server displays I/O levels, diagnostics data, and hosts ARC-WEB – a browser-based interface for smart phones, tablets, and computers.

Form, Fit and Function.  Prism 8×8, 12×12 and 16×16 have been designed using standard 19” x 1U enclosures. For convenient point-of-use or rack mounting, Prism 4×4 features 1/2 rack 1U form factor. (Surface and rack mount kits sold separately.)

Frequently Asked Questions

Prism

  • How many Dante channels does Prism support?

    Prism supports 64×64 Dante channels just like Edge and Radius.

  • What sample rate does the Prism operate at?

    Audio conversion is 24-bit, 48 kHz with internal processing of 40-bit floating point, 48 kHz.

  • How much delay memory is available in Prism?

    There is 174 mono seconds of delay memory total available in Prism.

  • How much latency is there in Prism?

    Analog inputs latency: 0.28 mS, Analog outputs latency: 0.60 mS, Total latency (A/D/A): 0.88 mS, inputs routed to outputs.

  • Is Prism’s phantom power 48V?

    Yes, Prism’s phantom power is a full 48 VDC @ 10 mA maximum per input.

  • Can the Prism 4×4 be rack mounted or surface mounted?

    Yes for both! The optional rack mount kit consists of a rack tray and two mounting screws. With this kit, one can rack mount one or two half rack products side-by-side in a single rack space. Alternately, the under table mounting kit consists of a U-shaped bracket and two mounting screws. With this kit, one can secure a single product under a table or to some other flat surface as necessary.

  • Does Prism have any more or less DSP processing power than the Radius or Edge DSP?

    Prism can provide the same DSP processing as the Radius and Edge, utilizing a 400 MHz SHARC processor.

  • Will SymVue work with Prism?

    Yes, Prism can access all of the features in Composer software available to Radius and Edge including SymVue and ARC-WEB.

  • Can Prism be used for acoustic echo cancellation processing?

    No, although they may be used in conjunction with other products performing this task.

  • Can Prism be used for directly interfacing with digital input and output sources?

    No, although they may be used in conjunction with other products performing this task.

  • Can Prism be interfaced with telco systems?

    No, although they may be used in conjunction with other products performing this task.

  • Can Prism be daisy-chained with other units?

    No, Prism has a single Ethernet port and a single Dante port, so a switch will be required to connect multiple units. Prism will not offer daisy chaining of Ethernet or Dante connections. Dante Redundancy is not an option with Prism.

  • Does Prisms built in ARC port offer as much power as Radius and Edge?

    Yes, Prism’s ARC port features 24V, 500 mA output to power connected ARCs, just like Radius and Edge.

  • Are Symetrix ARCs supported by Prism?

    Yes, all of the ARC models are supported by Prism, even the new ARC-3. Of course the ARC-PSe can be used as well.

  • Can I direct connect to Prism or do I need a switch?

    Yes, direct connection from your PC to Prism hardware is possible with each Prism model with a straight-through CAT-5 cable. A PoE+ injector is required for Prism 4×4.

  • Does Prism contain any local GPIO or is the xControl needed?

    Yes, the Prism does have local GPIO so the xControl is not needed in most cases. The Prism 4×4 has 2 analog control ports (2 pots or 4 switches) and 4 Logic Outputs built in. Prism 8×8, 12×12, and 16×16 have 4 analog control ports (4 pots or 8 switches) and 8 Logic Outputs built in.

  • How is Prism 4×4 powered?

    A PoE+ injector ships with the Prism 4×4, or a PoE+ switch can be used. Prism 8×8, 12×12, and 16×16 will use an external power supply with threaded barrel connector, which will be included.

  • Can the Prism be controlled by RS-232?

    Not directly. Due to its small form factor, there wasn’t room for an RS-232 connection on the back of Prism. However, Prism can still be controlled by UDP and TCP/IP over Ethernet. RS-232 control can be added by pairing the Prism with xControl.

  • How many inputs and outputs are available on Prism?

    The Prism is available in 4 sizes, 4×4, 8×8, 12×12, or 16×16. Prism is available with and without Dante, so Symetrix and third-party Dante expansion units can be added.
