  • A Paging and Background Music Control DSP
  • Total Solution Turn-Key Design
  • Near Zero Programming Time for Rapid Deployment

A Cost Effective DSP for Paging and Background Music Control.  Paging into 6 zones from 3 microphone locations, plus emergency page, with automatic ducking and priority arbitration.

Turn-Key Means Symetrix Did the Hard Work.  Plenty of inputs and outputs, the right kind of connectors, and a pre-designed GUI make for lightning fast deployment.

More Than Enough DSP.  All twelve input and six output channels feature a full complement of processing including: dynamics, feedback elimination, ambient noise sensing, EQ, and loudspeaker management resulting in a world class audio experience.

Comprehensive External Control Options.  ARC wall panels, ARC-WEB, and/or 3rd party touch-screens via RS-232 or UDP/IP.

An Embedded Web Server for Status and Even More Control.  Zone Mix 761’s embedded web server hosts ARC-WEB – a browser-based interface for smart phones, tablets, and computers.
