The TERRA-IEX, a 2 channel audio over IP encoder/decoder is the perfect solution to operate as an audio source for your IP network. You can encode mic/line balanced inputs or an optional S/PDIF input into an unicast/multicast. The same device provides you also 2 independent balanced outputs for fullduplex communication. By adding an USB memory stick, play lists can be used as backup of the decoded stream or as a source for the IP streaming. The volume and the channel can be modified locally with an IR remote control.
