QM-MD5x1, Slot 3 Digital Input Signal Descriptions (continued)
INPUT DESCRIPTION
RecallMicMixerPreset
Recalls the preset given by MicMixerPreset#
when the input is held high.
Recalling a preset adjusts the mixing levels for
remote MIC A-1 and MIC A-2.
High/1 (level-sensitive) = Recall mic mixer
preset; Low/0 = No preset recall
SaveAudioOutMixerPreset Saves the nine mixing levels for AUDIO OUT
(three mixing levels each for PRG L, PRG R and
SP) as defined by the nine …ToAudioOut…
analogs.
The mixing levels are saved to the preset given
by AudioOutMixerPreset# 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
RecallAudioOutMixerPreset Recalls the mixer preset given by
AudioOutMixerPreset# when the input is held
high.
Recalling a preset adjusts the nine mixing levels
for AUDIO OUT (three mixing levels each for
PRG L, PRG R and SP).
High/1 (level-sensitive) = Recall mixer preset;
Low/0 = No preset recall
QM-MD5x1, Slot 3 Analog Input Signal Descriptions
INPUT DESCRIPTION
MicMixerPreset# Sets the mic mixer preset number that will save
or recall the four mixing levels for remote MIC A-
1 and MIC A-2.
Valid analog values range from 1d to 16d. Out-
of-range values are ignored.
AudioOutMixerPreset# Sets the mixer preset number that will save or
recall the nine mixing values for AUDIO OUT
(three mixing levels each for PRG L, PRG R and
SP).
Valid analog values range from 1d to 5d. Out-of-
range values are ignored.
MicA-1ToMicMix Sets the mixing level for remote MIC A-1.
Remote MIC A-1 is mixed with remote MIC A-2.
The resulting “Mic Mix” is routed to the MIC1
channel of OUT and to the AUDIO OUT mixing
section for mixing into the speech and program
audio outputs.
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.
