Using the Equipment

Initially, four Audio Decoders are exposed to the user that are configured to output
two channels each but these can be expanded to eight Audio Decoders configured
to output one channel each that are then paired together.
This mode is manually selected by the user or automatically forced by Director's
OAC command Configure multiple radio services.

A single decoder is configured to output two channels. This could decode a
stereo audio stream, a mono audio stream (output to both channels) or a dual
mono audio stream.
A pair of single decoders are configured to output one channel each but are
paired together to artificially provide a dual mono output. Each decoder could
decode a mono audio stream or a stereo audio stream that is down-mixed to
mono. This will not work with a dual mono audio stream because one of the
channels will be lost.
