PPM Meters for Mono + IFB Programs
The codec is capable of broadcasting a bidirectional mono peer-to-peer audio stream and a separate
bidirectional IFB (talkback/communications) audio stream. By default, all inputs are mixed into the
outgoing mono program audio stream.
When both audio streams are connected, the codec displays a program audio mix of all inputs on
the LEFT PPM and mono return audio on the RETURN PPM. Outgoing talkback audio is displayed
on the RIGHT PPM.
The left hand Connections screen PPM meters display outgoing program audio on the SND PPM
and return audio on the RTN PPM. The right-hand PPMs display outgoing talkback (IFB) audio on
the SND PPM and incoming communications audio on the RTN PPM.
By default, return audio from the program audio stream (first connection) is routed to both analog
OUTPUT 1 (decoder 1) and OUTPUT 2 (decoder 2).
