(AMLMM)) is set to manual for that automixer, then the AMASGN command will fail and an ERROR#040 message
will be generated. If the microphone is removed from an automixer where it was a ssigned as the "Chairman
Mic" and chairman mode (
AMCHAIR) is enabled for that automixer, then an ERROR#041 message will be
generated. See the
ERROR command for more information on error messages. See Section 3.5 for more
information on dependencies within the automixer commands.
Although this command is a channel integer command, the increment and decrement operators (> and <) are
not supported for this particular command.
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 2, 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
F01AMASGN31
Assign input 3 to automixer
#1.
F01AMASGN31
F01AMASGN3?
Query current automixer
assignment for channel 3 .
F01AMASGN3x , where x is 0, 1, or 2 depending on

status message will be F01AMASGN31 .
F01AMASGN*0
Assign all mic inputs to no
automixer.
F01AMASGN*ääääääää

Assign inputs 1-4 to
automixer #1 and inputs 5-8
to automixer #2.
F01AMASGN*ààààåååå
F01AMASGN*?
Query automixer assignment
for all mic/line input
channels.
F01AMASGN*abcdefgh , where each of the letters (a,

automixer assignment for each channel. If this
command is issued after the example above, then the

8.9. AMAUTO -- Select Automatic or Manual Gating for each
Automixer Input
This command selects or queries the state of automatic or manual automixer gating thresholds for the specified
input channel. Automatic thresholds mean that the automixer adaptively determines the gating thresholds based
on current speech and noise levels using the gating ratio specified by the
AMGATER command. Manual thresholds
mean that the automixer uses the absolute threshold set via the
AMGATET command.
This command is a channel boolean command. See
Section 6.3 and Section 6.1 for more information on this type
of command.
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.
