Symetrix Radius NX 12x8 Audio Processor

The Symetrix Radius NX 12x8 Audio Processor is equipped with 128 redundant Dante channels. Dante protocol enables ultra-reliable multi-channel audio networking over IP. Together, Symetrix and Audinate's Dante provide the fastest possible way to implement, control, and maintain a system of networked DSPs and accessories - including third-party Dante-enabled end points.

Symetrix engineers, having worked with Dante for over ten years, leverage the protocol for box-to-box audio networking as well as peer-to-peer connection with major third-parties including AudioTechnica, Clockaudio, and Shure. In countless case studies, designers have benefited from the use of low cost off-the-shelf switches and cabling to link Symetrix DSPs with Dante-enabled mixing consoles, microphones, power amplifiers, loudspeakers, and computers.
