F01MGAINA,W,?
Query gain from
input A to W
Bus output.
F01MGAINA,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 F01MGAINA,W,-12 .
F01MGAINWB0,WM0,-3
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).
F01MGAINWB0,WM0,-3
F01MGAIN1,*,ääääääää{{{{ääÇÇÇÇ
Set all
crosspoint gains
for input
channel 1. Set
the gain to
outputs 1-8 to 0
dB (ä), the gain
to outputs A-D
to -9 dB ({), the
gain to AEC
reference 1 and
2 to 0 dB (ä),
and the gain to
bus outputs W,
X, Y, and Z to -3
dB (Ç).

F01MGAINB,*,-3
Set all
crosspoint gains

F01MGAINB,*,ÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇÇ
F01MGAINB,*,>12
Increase the
gain for all
crosspoints of
input channel B
by 12 dB.
F01MGAINB,*,abcdefghijklmnopqr , where
the value of each of letters (a, b, etc.) depends on
the current state of each of the crosspoint gains. If
this command was issued after the example above,
then the status message would be
F01MGAINB,*,èèèèèèèèèèèèèèèèèè
F01MGAINB,*,?
Query the gains
for all
crosspoints of
input channel B

F01MGAINB,*,abcdefghijklmnopqr , where
the value of each of letters (a, b, etc.) depends on
