Use the DEMUX (demultiplex) web page ( Figure 18 on page 34 ) to:
• Select which AES/EBU audio groups to extract from the incoming SDI
video signal and output as two digital audio outputs.
• Enable/disable sample rate conversion and loss of signal reporting for
the selected audio group.
An illustration of the possible embedded audio groups in the incoming SDI
video is shown in
Figure 17 . There are four possible groups of audio carried
in an SDI video signal. Each group contains two streams of audio, AES 1
Ch 1 and Ch 2 and AES 2 Ch 1 and Ch 2. The module can demultiplex one
group of audio to be output to the balanced or unbalanced AES audio con-
nectors on the KAM-AES-R rear module. The group is selected on the
Demultiplex Web Page on page 34 .
Embedded audio must be present and reported to be extracted. You may
also choose to not extract audio.
