8.15. AMGATER -- Set Automixer Gate Ratio
This command sets the automixer gate ratio (in dB) for the specified input channel. The gate ratio is the ratio of
the speech power to noise power required to gate the microphone on. This value is only used if the input is set
to automatic gating via the
AMAUTO.
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 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.

gating threshold to 12 dB
for input channel 3 .
F01AMGATER312
F01AMGATER3>3
Increase gate ratio for
automatic gating threshold
by 3 dB for input channel 3
.
F01AMGATER3x , where x is between 0 and 100
depending on the current setting of the gate ratio for
input channel 3 . If this command is issued after the
example above, then the status message will be
