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.)
