STEREO RETURNS
2 Stereo return inputs are provided to return
the effects ('wet') signal, usually from a stereo
device, to the mix. These are normally routed
to the main L-R mix but may be returned to the
corresponding pairs of subgroups for group
effects (1-2 or 3-4).
These inputs may also be used as additional
line inputs, or as external inputs to the matrix
mix by selecting A-B. The BAL control adjusts
the balance between left and right signals, or
can be used as a pan control to route the signal
to one side only by rotating fully. A smooth
travel 60mm fader provides precise control of
the level.
MONITOR
MODE
Select your required
application: LR sum mono
out FOH, or AFL
interrupted by PFL,
STAGE MONITOR.
Press the mode switch for stage monitor application.
The mono out XLR now feeds the monitor engineers
'listen wedge' speaker. It is advisable that the same type
of loudspeaker is used for this as those used for the
stage monitors themselves.
PHONES MONITOR
Plug in stereo headphones (150 to 600 ohms
recommended) under the armrest. Adjust the LEV
control for comfortable listening level. The phones
and 12 segment bargraph meters normally monitor the
post-fade L-R mix. Press 2-TRK to monitor the return
from a stereo recorder if connected.
Pressing AFL anywhere on the console automatically
overrides the monitor with the selected AFL signal.
Pressing PFL overrides both the monitor source and
any selected AFL. This feature lets you listen to an
AFL source, group for example, and check channel
signals simply by pressing and releasing the required
PFL buttons. PFL or AFL selected is indicated by
means of a large red LED above the meters.
L,R,M OUTPUTS
The main L and R outputs are individually
controlled on two 100mm long throw faders.
The outputs are balanced XLR to drive long
cable runs. INSERT points are provided so
that signal processors such as compressors or
limiters may be patched into the signal path.
Left and right signals are summed together to
the balanced XLR MONO output which may
be used to feed a centre fill speaker system,
provide a mono broadcast or recording feed, or
work a mono PA with capability for stereo
recording.
Normal
f a d e r
position
The L/Mono and R inputs
are on individual jack sockets.
Sensitivity is for line level
signals of -10dBV and more.
For a mono source plug into
the L input only.
