MAIN MIX MASTERS
Using the Engineers Wedge Monitor
It is best to use the same type of monitor speaker
as provided on stage. This lets the engineer hear
the sound as the performer hears it.
Select the underpanel WEDGE MODE switch to
configure the C output as the engineers wedge
monitor. Use the insert to patch in any processing
required, for example a graphic EQ to preview
changes in the monitor before applying them to the
mix being checked.
Select LR, C, 2-TRK or none as the default monitor
source. Pressing AFL overrides the source to listen
to a selected output. Pressing PAFL overrides any
AFL selection to check one or more inputs.
Releasing PAFL restores the previously selected
AFL. This is well suited to monitor mixing where
you need to listen to the mixes in turn but quickly
check individual inputs along the way.
Pressing the TALK TO TB switch automatically
dims the output by 20dB to prevent feedback
between the local speaker and talkback mic.
MUTE. This momentary action switch turns the
master signal on or off. It can also be muted by the
mute groups, snapshot memories (externally
controlled) and MIDI note on/off messages. The
switch illuminates when the signal is muted.
The switch also functions as an edit key when in
EDIT GROUPS or EDIT SAFES mode. The mute
status is always displayed on the switch regardless
of operating mode.
SAFE / EDIT. This green LED has a different
function according to console mode:
Normal The LED lights when the master has been
made safe from the snapshot and MIDI automation.
Edit Safes Continues to indicate which masters
are automation safe while they are edited.
Edit Groups The LED lights to indicate that the
master is assigned to the MUTE group.
WEDGE MODE. This underpanel mode switch
configures the C output to become the engineers
monitor when the console is used for the stage
monitor application. When pressed the monitor
source is routed in mono through the C insert and
fader to the main output. The C mix bypasses this
section and is available from the matrix outputs if
needed. The yellow LED lights when wedge mode
is selected. The switch is protected to prevent
accidental operation. Use a pen or pointed
implement to select the required mode.
PEAK. The red PK LED senses the signal both
pre and post master fader and lights to warn when
the main mix is within 5dB of clipping. Reduce the
inputs to the mix if the LED flashes.
FADER MASTER. The main mix L,R and C each
have a 100mm smooth travel ALPS K-fader
providing +10dB gain above the nominal 0dB
operating position. These faders are not part of the
console VCA group system.
