GROUP / AUXILIARY SENDS
These controls send the channel signal to the audio
groups 1-4 and aux sends 1-8. The layout is the
same for both the mono and stereo channels. For
the stereo channels the left and right signals are
combined to feed the mono auxes.
AUX SEND 1-4. These rotary controls adjust how
much channel signal is sent to the mono auxiliary
outputs 1-4. The 0dB position is marked at 3
o’clock. An extra +6dB boost is available. These
sends together with their rotary master controls are
usually used to feed the effects devices in FOH
mode. In MONITOR mode they would usually
provide monitor sends.
AUX SEND 5-6. These rotary controls adjust how
much channel signal is sent to the mono auxiliary
outputs 5-6. The 0dB position is marked at 3
o’clock. An extra +6dB boost is available. These
sends together with their fader master controls are
used for effects or monitor sends.
AUX SEND 7-8. These rotary controls adjust how
much channel signal is sent to the mono/stereo
auxiliary outputs 7-8. They function according to
the position of the STEREO switches described
below. An extra +6dB boost is available.
STEREO. This configures aux 7-8 for mono or
stereo operation. In the up position they become
independent mono sends. In the down position
they become a stereo pair with separate level and
pan controls. For the stereo channels the left and
right signals are combined to provide mono feeds
when the switch is in the up position. When
pressed they are routed in stereo to the pair of
auxes.
PRE. Switches the channel pre-fade signal to the
auxiliary outputs. Aux 1-4 is switched as a group of
four, aux 5-6 and 7-8 are switched in pairs. In the
up position the source is post-fade. When pressed
the source is pre-fade. The pre-fade source follows
the setting of the internal jumper links.
ROUTING SWITCHES. These route the channel
signal to the audio groups in pairs 1-2 and 3-4. The
signal is post-fader and follows the pan control.
Mono or stereo groups can be created using the
pan control. The LCRplus blend control does not
affect the signal routed to the groups.
