Several digital audio attributes may be assigned. The defaults are Resolu-
tion
20 bit , Audio Mode Normal (Stereo) and Block Align On .
Resolution:
This attribute determines how the signal bits are processed. A signal has 24
bits with the last four bits designated as auxiliary (AUX) bits.
In 20 bit mode the four AUX bits pass through the router unaffected by any
processing. If channels A and B are swapped, the four AUX bits stay in the
same place. If the signal is muted, the four AUX bits are not muted.
In 24 bit mode the router will treat the four AUX bits as though they are part
of the audio data. If Channels A and B are swapped, the four AUX bits will
swap locations. If the audio is muted, the four AUX bits will be muted.
