PPM Meters for Stereo + IFB Programs
The codec is capable of broadcasting a bidirectional stereo peer-to-peer audio stream and a
separate bidirectional IFB (talkback/communications) audio stream. Inputs 1-3 are routed to both
encoders 1 and 2. To provide stereo on the auxiliary input, the left channel is routed to encoder 1
and the right channel is routed to encoder 2.
By default, outgoing stereo program audio is displayed on the LEFT PPM and RIGHT PPM. A mono
mix of stereo return audio is displayed on the RETURN PPM.
The left hand Connections screen PPM meters display outgoing program audio on the SND PPMs
and return audio on the RTN PPMs. The right-hand PPMs display outgoing talkback audio on the
SND PPM and incoming communications audio on the RTN PPM.
By default, stereo return audio is routed to analog OUTPUT 1 (decoder 1) and OUTPUT 2 (decoder
2).
