F01AGC*2
Toggle AGC state on input channels 1-
8.
F01AGC*abcdefgh, where a-h are each 0 or 1 depending
on the current state of the AGC for each of the eight input
channels.
F01AGC*?
Query AGC state on input channels 1-
8.
F01AGC*abcdefgh, where a-h are each 0 or 1 depending
on the current state of the AGC for each of the eight input
channels.
8.5. AGCMAX -- Set Maximum Allowed Mic/Line Input AGC Gain
This command sets the maximum gain that the AGC can apply on input channels 1-8 . For example, if AGCMAX is
set to 10, then the AGC for that channel can apply a maximum of 10 dB of gain to the input signal.
This command is a channel integer command. See
Section 6.3 and Section 6.2 for more information on this type
of command. The minimum and maximum values for this command are 0 and 15, respectively.
This command is saved to non-volatile memory only as part of a preset. The state of this command will be
restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
