IP Audio Encoder/Decoder The TERRA-IEX is a 2 channel audio over IP encoder/decoder which operates as an audio source and streams its inputs in unicast or multicast such as a microphone shall be connected to the mic input and be encoded in G.722. The TERRA-IEX shall also come with 2 balanced outputs for Full Duplex communication or for local outputs, and 3 contact inputs and 2 contact outputs.

By using an optional USB 2.0 interface, the playlists shall be used as a back up of the decoded stream or as as source for the IP streaming. The volume and the channel selection can be modified by RAC remote source selector.
