MATRIX and 2-TRACK
4 Matrix outputs are available. Each has 11
sources derived from group 1-8 and the LRC main
mixes. Conveniently positioned away from the
other controls, these can be used to create
independent mixes for distributed speaker systems,
recording, broadcast, video and other special feeds.
They include mute switches, talkback assign,
balanced XLR outputs and mono/stereo AFL.
GROUP 1-8. Each of the 8 groups can be mixed
into the matrix. The source is derived post-fader.
Adjust the level clockwise from fully off to +6dB
boost. The ‘0dB’ position is marked.
L,R,C. Each channel of the main output can be
mixed into the matrix. The source is derived post-
fader. Adjust the level clockwise from fully off to a
maximum +6dB boost.
TB ENABLE. Press this to enable talkback to the
matrix output. When selected, pressing the TALK
TO TB switch routes the talkback mic signal, or
pressing the OSC/NOISE TO TB switch routes the
oscillator/noise generator signal to the output.
When not selected, pressing these switches does
not affect the output. The talkback and osc/noise
signals are routed pre master level.
MASTER LEVEL. Adjusts the matrix output level
from fully off to a maximum boost of +6dB. The
normal ‘0’ position is marked.
MUTE. This latching switch turns the matrix
master signal on or off. It is not part of the console
mute group and automation system. The switch
illuminates when the signal is muted.
AFL. Press this switch to listen to the matrix signal
in the headphones or engineers monitor without
affecting the main outputs. The signal is monitored
post-level, pre-mute so that it can be checked while
the output is muted.
This switch has the same capability as the fader
master section AFL. Includes momentary or
latching action, add or auto-cancel mode, all clear
and PAFL override AFL logic.
Mono or stereo AFL. Press a single AFL switch
to listen to that matrix as a mono signal fed to both
left and right channels of the headphones and local
monitor. Press two related AFL switches together
to listen to a related pair in stereo, ideal when
checking stereo sends. The odd number master is
fed to the left channel, even to right.
