DESCRIPTION
Indicates the gating level for the corresponding
MIC/LINE input.
Adjusts the gain of the MIC 1/LINE 1 or MIC
2/LINE 2 input.
Valid values range from 0% to 100%. This maps
into the following range:
Mic level input: -60dBV to -20dBV
Line level input: -28dBV to +12dBV
Indicates the gain being applied to the
corresponding MIC/LINE input.
Sets the time, in milliseconds, that it takes for the
noise gate to fully open after the signal exceeds
the <GatingLevel>. This prevents short spikes in
the input signal level, such as coughing, from
opening the gate.
The attack time applies to both microphones.
Valid analog values range from 0d (0ms) to 100d
(100ms), with 10d to 40d being the most usable
range.
Out of range values are ignored.
Indicates the attack time.
Sets the time, in milliseconds, over which the
noise gate will close. This prevents the sound
from stopping too abruptly—for example, during
brief pauses in speech.
The decay time applies to both microphones.
Valid analog values range from 0d (0ms) to 5000d
(5000ms, or 5s), with 1000d to 3000d (1000s to
3000s, or 1s to 3s) being the most usable range.
Out of range values are ignored.
Indicates the decay time.
Sets the four MIC 1 EQ trims (at 160Hz, 500Hz,
1.2kHz, and 3kHz).
Valid analog values range from -120d (-12dB) to
+120d (+12dB), adjustable in increments of 0.1dB
(1d = 0.1dB).
A trim of 0d (0dB) means that the signal will pass
unaffected.
Indicates the trim being applied to each band of
the MIC 1 equalizer.
Sets the four MIC 2 EQ trims (at 160Hz, 500Hz,
1.2kHz, and 3kHz).
Valid analog values range from -120d (-12dB) to
+120d (+12dB), adjustable in increments of 0.1dB
(1d = 0.1dB).
A trim of 0d (0dB) means that the signal will pass
unaffected.
Indicates the trim being applied to each band of
the MIC 2 equalizer.
