Network-powered CobraNet Product Reference Platform

The CobraCom™ Reference Platform provides a complete, board-level design kit demonstrating the simplicity of implementing network-powered CobraNet® digital audio devices. Through real-time transport of uncompressed digital audio over ubiquitous Ethernet, CobraNet combines the routing flexibility of a network with pro quality, multi-channel audio. By providing one channel of speaker level audio output, one channel of microphone input, 32-bit audio DSP, GPIO for a simple user interface, RS-232 and standard Power-over-Ethernet (PoE) power conditioning, many different networked products can be developed.

Features

  • Two pro quality, uncompressed digital audio channels in, two channels out (2x2)
