The TERRA-IEX is a 2-channel audio over IP encoder/decoder that functions as an audio source for an IP network. It comes with 2 independent balanced line outputs for full-duplex communication for paging and broadcasting.

By using an optional USB 2.0 interface, playlists will be used as a backup for the decoded transmission or as a source for IP transmission. Volume and channel selection can be adjusted using the remote source selector RAC.
