I have a Biamp Nexia VC DSP, which has a Codec input and output on the back.
The manual doesn't say anything more than: "This plug-in barrier strip connector provides a balanced input for line-level audio signals from a codec."
I'm having a hard time wrapping my head around what a "Codec" is in this context.
The software gives me some control blocks, and I know it has something to do with video conferencing, but I have no idea how it's implemented, and googling "codec" is not helpful.
What do I plug into a codec input and output?
