Basic Tab – Secondary Audio Support
A dual-channel 9223-SA can be configured to offer secondary audio support (i.e., a second audio
PID in the same program). If this function is available, it will be available in the audio section of
Encoder 1, as indicated below:
When Secondary Audio is set to Enabled, the Encoder 1 Audio Configuration section will
change as indicated below:
The individual controls work in the same manner as discussed before. Each audio channel can
be independently configured. As before, the SDI Embedded Audio option will only be available
if the Encoder 1 input selection is one of the SDI variants. The only input restriction is that,
when using Analog Audio, the signal connected to Video/Audio 1 will be the first audio channel,
and the signal connected to Video/Audio 2 will be the second audio channel.
