Description
Set gain from input B
to AEC reference 1 to -
3 dB.
Increase gain from
input 1 to output B by
6 dB.
Query gain from input
A to W Bus output.
Set crosspoint gain in
EF Bus submatrix on
crosspoint that routes
the W bus signal from
the device at ID0
(WB0) to W submatrix
output 0 (WM0).
Set all crosspoint gains
for input channel 1.
Set the gain to output
1 to 0 dB (ä), the gain
to outputs A-B to -9 dB
({), the gain to AEC

Status Message
Q01MGAINB,R1,-3
Q01MGAIN1,B,x where x is the new value of
the crosspoint gain. If the crosspoint gain was
set to -3 dB before this command, then the
status message would be Q01MGAIN1,B,3 .
Q01MGAINA,W,x , where x is the current value
of the crosspoint gain. If the crosspoint gain
was set to -12 dB before this command, then
the status message would be Q01MGAINA,W,-
12 .
