LAMP
Plug in a 12V gooseneck lamp to provide illumination of the control
panel. This should be a BNC connector type.
Individual jack sockets are provided for left and right inputs (returns)
from and outputs (sends) to a stereo recorder such as a DAT or
cassette machine.
Alternatively the RETURN may be used for stereo intermission
replay from a CD or similar to the main mix by pressing L-R . An
LED warns that replay is on.
The SEND may be used for recording the performance in stereo, or
to feed alternative speakers, drive an induction loop hearing aid
system, or to feed a stereo broadcast etc. The send is connected post
L-R faders as standard.
Separate send and return level controls adjust the signal to the
required line level and sensitivity. The console can work with both
high (+4dBu) and low (-10dBV) level equipment.
2-TRACK
Plug in stereo headphones (30 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.
MONITOR MODE
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.
Select your required application: LR sum mono out FOH , or AFL
interrupted by PFL, STAGE MONITOR .

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 feed 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. The
MONO output is post fade but can
be set pre-fade by changing internal link options.
