Zone Mix 761
- 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.
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. Zone Mix 761’s embedded web server hosts ARC-WEB – a browser-based interface for smart phones, tablets, and computers.
Help is built in. The software connection wizard provides fast and easy IP linking to the DSP hardware. The external control wizard guides effortless programming of multiple user control devices. Learn more about the Zone Mix 761 software here.
