Data Sheet Overview
Prism 4×4, 8×8, 12×12, and 16×16 DSPs provide sophisticated state of the art audio signal processing at price points that were unimaginable only a few short years ago. The same uncompromising analog and digital design found in the Symetrix top of the line DSPs is now available across the Prism family.
Dante™ in our DNA
All Prism models are optionally available equipped with 64×64 Dante channels. Dante is an uncompressed multi-channel digital media technology. Symetrix designs and supports one, and only one, network audio protocol: Audinate’s Dante. Symetrixand Dante provide the fastest way to implement, control and maintain a system of networked DSPs and accessories – including select third-party products.
Scale Up
Increase a Prism system’s analog input and output count using Symetrix Dante-enabled xIn 4, xIO 4×4, xOut 4, xIn 12, and xOut 12 expanders.
Total Design Control
Program Prism using Symetrix’ award winning Composer open-architecture Windows CAD application.
Connect to the Outside World
Connect to Ethernet equipped touch panels, W Series wall remotes, and any of the Symetrix ARC wall panels including the ARC-3 with graphical menus and universal mounting options.
Form, Fit, and Function
Prism 8×8, 12×12 and 16×16 models are 19” x 1U. Prism 0x0 and 4×4 are 1/2 rack x 1U. (Surface and rack mount kits sold separately).
Embedded Web Server for Status and Control
Prism’s embedded web server displays analog I/O levels, diagnostics, and provides access to ARC-WEB, a remote interface accessible from any smart phone, tablet or computer. The embedded server is accessible using any popular web browser by entering Prism’s local LAN, or publicly accessible IP address or its fully qualified domain name into the browser’s address field.
Prism 16×16 Overview
The Prism family is the workhorse series in Symetrix’s DSP lineup. With all the core features needed for the most common applications, it provides powerful processing with flexible control, and optional Dante networking. Prism is ideally suited for applications requiring powerful, extremely cost effective advanced signal processing coupled with a standardized means for future expansion.
- 16 analog in and out, and powerful Symetrix DSP reduce overall system costs.
- Optional 64×64 Ultra low latency Dante network audio protocol uses standard IT infrastructure.
- Industry leading analog and A/D/D/A performance, 48 volt phantom mic power.
- Configured using award winning Composer software. Controlled from W Series remotes, ARC wall panels, ARC-WEB and T Series
touchscreens. Embedded web server enables remote metering and diagnostics. - Front panel LCD provides configuration information, system status, and analog audio levels
- Power: Switching power supply providing 24 VDC @ 1.4 amperes. NOTE: Each power supply will accept a 100-240 VAC input.
- ARC: Distributes power and RS-485 data to one or more ARC devices.
- Dante: 1000 Base-T Ethernet port provides 128 (64×64) channels of Dante network audio. Requires optional factory installed Dante card.
- Ethernet: 10/100 Base-T Ethernet port for Symetrix Composer host control, third-party accessory controllers over IP, and power. Features auto-crossover sensing for direct device-to-device connections.
- Factory Reset Switch: To be used under the supervision of technical support, it has the ability to reset the unit’s network configuration and completely reset the unit to factory defaults.
- Logic Outputs: Eight (8) logic outputs with four (4) paired common ground pins. Logic Outputs go low (0 V) when active, and are internally pulled high (5 V) when inactive and can drive external LED indicators directly.
- External Control Inputs: Four (4) analog control inputs able to be used as 4 potentiometer inputs or as 8 switch inputs (+3.3 VDC reference voltage supplied).
- Analog Line Outputs: Sixteen (16) balanced analog line level audio outputs, with individually software-controllable +/- 24 dB of digital trim and mute.
