8.20. AMLMN -- Set Microphone That Will Remain On in Manual
Last Mic On Mode
This command sets the microphone number that will remain on when "last mic on" mode is set to manual (see
the
AMLMM command). The first argument to this command is the number of the automixer (1-2) that will be
adjusted. The second argument is the microphone number (1-8) that should be gated on if no other mics are
gated on and
AMLMM is set to manual. The value of the AMLMN command is only valid when AMLMM is set to
manual.
If "last mic on" moce is set to manual for the specified automixer and the AMLMN command attempts to specify a
microphone that does not belong to the automixer, then the AMLMN command will fail and an ERROR#043 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.
Even though this is a channel integer command, use of the wildcard character for the automixer number is not
supported.
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 8, 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.

8.21. AMNOM -- Set Local Maximum Number of Open Mics for
Automixer
This command sets the local maximum number of open mics (NOM) allowed for the specified automixer. The
NOM limit is a local limit, meaning that this limit applies only to the specific Vortex that is is set on. In contrast,
the
AMGNOM command is a global limit that applies to all linked Vortex automixers with the same AMBUSID.
The first argument of this command specifies the automixer number (1-2) to adjust. The second argument
specifies the NOM limit (1-8) . Even though this is a channel integer command, use of the wildcard for specifying
the automixer number is not supported.
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 64, 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.
