Audio Server

The Audio Server is a repackaged commercial off-the-shelf (COTS) Digital Audio Network Server that provides automatic mixing, gain control, gating, and acoustic echo cancellation for VTC headsets and a CODEC. Multiple CODEC interface configurations are possible.

The repackaging facilitates connector compatibility with existing aircraft architecture, meets the constraints of a 19” rack installation, and retains all controls and indicators from the COTS device.

The Audio Server has fully automatic function and requires no user interaction.

The Audio Server is designed to be paired with the Audio Interface Panel. (Note that CSI’s POE Switch is also required to power the Audio Interface panels and interface them to the Audio Server.)
