QM-MD7x2, Slot 2 Analog Input Signal Descriptions
INPUT DESCRIPTION
Mic1EQTrim1 through
Mic1EQTrim4 and
Mic2EQTrim1 through
Mic2EQTrim4
Applies EQ trim to each band; 160 Hz (Trim1), 500
Hz (Trim2), 1.2k Hz (Trim3), and 3k Hz (Trim4) of
the MIC 1 and MIC 2 equalizers.
Valid analog values range from -120d (-12 dB) to
+120d (12 dB), adjustable in increments of 0.1 dB.
Thus changing the analog value by 1d signifies a
boost or attenuation of 0.1 decibels.
A trim of 0d (0 dB) means that the signal will pass
unaffected.

OUTPUT DESCRIPTION
Mic1Mute_F and Mic2Mute_F
When high, indicates that the corresponding mic
input is muted.
High/1 = Mic audio is muted; Low/0 = Mic audio is
not muted
Mic1GatingEnable_F and
Mic2GatingEnable_F
Indicates the status of the noise gate for MIC 1 or
MIC 2.
High/1 = Gating is enabled; Low/0 = Gating is
disabled
Mic1Gate and Mic2Gate
Indicates that the signal level on MIC 1 or MIC 2
has exceeded the
GatingLevel
.
High/1 = Gating level exceeded; Low/0 = Gating
level not exceeded
Mic1Nominal and
Mic2Nominal
Indicates that the signal level on MIC 1 or MIC 2
has exceeded the nominal level.
The nominal indication is reported at 10% of the
maximum level supported by the hardware, or 20
dB below the input clip level.
High/1 = Nominal level exceeded; Low/0 =
Nominal level not exceeded
Mic1Clip and Mic2Clip
Indicates that the signal level on MIC 1 or MIC 2
has exceeded 50% of the maximum level
supported by the hardware, or 6 dB below the
input clip level. This signifies a mic-level that is too
hot.
High/1 = Mic signal clipping; Low/0 = Mic-level not
clipping
Mic1PhantomEnable_F and
Mic2PhantomEnable_F
Indicates that phantom power to MIC 1 or MIC 2
has been enabled.
High/1 = Phantom power is on; Low/0 = Phantom
power is off

OUTPUT DESCRIPTION
Mic1GatingLevel_F and
Mic2GatingLevel_F
Indicates the gating level for MIC 1 and MIC 2.
Mic1Gain_F and Mic2Gain_F
Indicates the gain that is being applied to MIC 1 or
MIC 2.
AttackTime_F
Indicates the attack time in milliseconds.
DecayTime_F
Indicates the decay time in milliseconds.
Mic1EQTrim1_F through
Mic1EQTrim4_F and
Mic2EQTrim1_F through
Mic2EQTrim4
Indicates the trim being applied to each band of
the MIC 1 and MIC 2 equalizers.
