F01AGCMIN1?
Query the AGC minimum
gain on input channel 1 .
F01AGCMIN1x where x is a number between -15 and
0, depending on the current setting of the AGC
minimum gain on input channel 1 .
F01AGCMIN*-6
Set AGC minimum gain on
input channels 1-8 to -6 dB.
F01AGCMIN*~~~~~~~~
F01AGCMIN*ääääüüüü
Set AGC minimum gain on
input channels 1-4 to 0 dB
and AGC minimum gain on
input channels 5-8 to -3 dB.
F01AGCMIN*ääääüüüü
F01AGCMIN*?
Query AGC minimum gain on
input channels 1-8.
F01AGCMIN*abcdefgh, where a-h are each between
u and ä, depending on the current setting of the AGC
minimum gain for each of the eight input channels.
8.7. AGCRATE -- Set Ramp Rate of Mic/Line Input AGC
This command sets or queries the maximum rate at which the AGC can increase or decrease the gain of the
signals on input channels 1-8 . The ramp rate is expressed in dB/sec.
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 1 and 5, 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.
Example Description Status Message
F01AGCRATE13

on input channel 1 .
F01AGCRATE*5
Set AGC ramp rate on input
channels 1-8 to 5 dB/sec.
F01AGCRATE*ëëëëëëëë
F01AGCRATE*ààààêêêê
Set AGC ramp rate on input
channels 1-4 to 1 dB/sec
and AGC ramp rate on
input channels 5-8 to 4
dB/sec.
F01AGCRATE*ààààêêêê
F01AGCRATE*?
Query AGC ramp rate on
input channels 1-8.
F01AGCRATE*abcdefgh, where a-h are each between
à and ë, depending on the current setting of the AGC
ramp rate for each of the eight input channels.
8.8. AMASGN -- Assign Inputs to an Automixer
This command is used to assign one of the mic/line inputs (1-8) to an internal automixers. Setting AMASGN to 0
for a given input channel corresponds to no automixer, 1 corresponds to Automixer #1 , and 2 corresponds to
automixer #2.
An AMASGN command usually removes a microphone from one automixer and adds it to another. If the
microphone is removed from an automixer where it was assigned as the "Last Mic On" and list mic mode
