QM-MD7x2, Slot 4 Digital Input Signal Descriptions (continued)
INPUT DESCRIPTION
RecallMicMixer1Preset
Recalls the preset given by
MicMixer1Preset#
when the input is held high.
Recalling a preset adjusts the mixing levels for
remote MIC A-1 and MIC A-2, and local MIC 1 and
MIC 2.
High/1 (level-sensitive) = Recall mic mixer preset;
Low/0 = No preset recall
SaveAudioOut1MixerPreset
Saves the nine mixing levels for AUDIO OUT 1
(three mixing levels each for PRG L, PRG R and
SP) as defined by the nine
…ToAudioOut1…
analogs.
The mixing levels are saved to the preset given by
AudioOut1MixerPreset#
when the input is held
high.
If the save is asserted at the same time as a recall,
the recall takes precedence and the save is
ignored.
High/1 (level-sensitive) = Save mixer preset;
Low/0 = No preset save
RecallAudioOut1MixerPreset
Recalls the mixer preset given by
AudioOut1MixerPreset#
when the input is held
high.
Recalling a preset adjusts the nine mixing levels
for AUDIO OUT 1 (three mixing levels each for
PRG L, PRG R and SP).
High/1 (level-sensitive) = Recall mixer preset;
Low/0 = No preset recall
QM-MD7x2, Slot 4 Analog Input Signal Descriptions
INPUT DESCRIPTION
MicMixer1Preset#
Sets the mic mixer preset number that will save or
recall the four mixing levels for remote MIC A-1
and MIC A-2 and local MIC 1 and MIC 2.
Valid analog values range from 1d to 16d. Out-of-
range values are ignored.
AudioOut1MixerPreset#
Sets the mixer preset number that will save or
recall the nine mixing values for AUDIO OUT 1
(three mixing levels each for PRG L, PRG R and
SP).
Valid analog values range from 1d to 16d. Out-of-
range values are ignored.
MicA-1ToMicMix1
Sets the mixing level for remote MIC A-1. Remote
MIC A-1 is mixed with remote MIC A-2, local MIC
1, and local MIC 2. The resulting “Mic Mix 1” is
routed to QM OUT 1 and to the AUDIO OUT 1
mixing section.
Valid analog values range from -800d (-80 dB) to
0d (0 dB), adjustable in increments of 0.1 dB.
Changing the analog value by 1d signifies a boost
or attenuation of 0.1 decibels.
A value of -800d (-80 dB) signifies the minimum
mixing level and will cut the mixing level to a
complete mute. A mixing level of 0d (0 dB) means
that the signal will pass unaffected.
