Figure 2-3b. PM4000 Master Module
(aux send and group sections of module)
33. CUE (Matrix cue)
Pressing this switch part-way down causes
momentary contact; pressing it further locks it
down. When the CUE switch is illuminated, the
module’s matrix mix signal (post insert point, pre
MTRX MASTER) replaces any other signal in the
Cue output and the Phones output unless an
input CUE switch is engaged. (Bus cue signals
are overriden by input cue.) The MTRX CUE
signal is Mono, regardless of how many matrix
channels are cue’d.
34. ON (Matrix On)
This locking, illuminated switch turns on when
the MTRX OUT is ON. When the MTRX OUT is
turned OFF, its signal may still be previewed
with the adjacent CUE switch [33].
AUX SEND MASTER SECTION
35. LEVEL (Aux send level)
This rotary control adjusts the overall level from
the correspondingly numbered auxiliary mixing
bus to the AUX OUT connector.
36. INSERT (Aux insert)
The aux send master circuit has an insert Out/In
patch point located just before its master level
control. The OUT jack is always active. If this
switch is engaged (LED illuminated), the IN jack
becomes active. Thus, engaging the INSERT
switch can insert a signal processor in the aux
channel, or it can substitute an external line-level
input instead of the mixed aux signal.
37. CUE (Aux send cue)
Pressing this switch part-way down causes
momentary contact; pressing it further locks it
down. When the CUE switch is illuminated, the
correspondingly numbered auxiliary send re-
places any master cue signal in the Cue output
and the Phones output unless an input CUE
switch is engaged. (Bus cue signals are overriden
by input cue.) The aux cue signal is mono, regard-
less of how many aux sends are cue’d.
38. ON (Aux On)
This locking, illuminated switch turns on when
the AUX OUT is on. When the AUX OUT is
turned off, the feed to the VU meter is also off,
although the signal may still be previewed with
the adjacent CUE switch [36].
