Audio Processing
Depending upon your unit’s options, the X75HD/X75SD can process
up to 16 or 8 channels (8 or 4 stereo channels) of audio simultaneously
with video. Any combination of audio is assigned from the inputs (four
channel analog audio, 5/2 AES balanced or unbalanced, up to four
groups demuxed from the SD-SDI and HD-SDI input) into the
16-channel processor.
Processed audio signals can be mapped to all outputs. When you select
one audio input set, mono channels are mapped intelligently to provide
outputs to all available channels. Audio outputs include the following:
four channel analog audio, 5/2 AES balanced and unbalanced, up to
four groups muxed into the SD-SDI and HD-SDI outputs.
Figure 1-8 on page 30 illustrates the audio processing flow in a
16-channel X75HD unit; Figure 1-9 on page 31 illustrates the audio
processing flow in an 8-channel X75SD unit.
