F01AMNOMAT*?
Query NOM
attenuation status of
all outputs.
F01AMNOMAT*abcdefghijkl , where each of the
letters (a, b, etc.) is either 0 or 1 depending of the
current status of the NOM attenuation on the
corresponding output. If this command was sent after
the example above, then the status message would be
F01AMNOMAT*000000001111 .
8.23. AMOFFAT -- Set Off Attenuation for the Specified Automixer
This command sets the off attenuation (in dB) for the specified automixer. Setting this value to 18 would result in
the microphone signals being attenuated by 18 dB when gated off. This value is set independently for each of
the automixers. The first argument of this command specifies the automixer number (1-2) to adjust. The second
argument specifies the off attenuation.
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 100, 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
F01AMOFFAT118
Set off attenuation for automixer 1 to
18 dB.
F01AMOFFAT118
F01AMOFFAT2?
Query current off attenuation for
automixer 2 .
F01AMOFFAT2x , where x is between 1 and 100
depending on the current setting of the off
attenuation for automixer 2 .
8.24. AMPRIOR -- Set Gating Priority for the Specified Mic
This command sets the automixer gating priority for the specified input channel. Priority levels of 1-4 are allowed
with 1 being the highest priority and 4 being the lowest.
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 4, 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
F01AMPRIOR11
Set microphone input 1 to
gating priority 1.
F01AMPRIOR11
F01AMPRIOR24
Set microphone input 2 to
gating priority 4.
F01AMPRIOR24
F01AMPRIOR3?
Query current gating
priority for microphone
input 3. .
F01AMPRIOR3x , where x is between 1 and 4
depending on the current gating priority setting for
microphone input 3. .
