AUXILIARY SENDS These controls route the channel signal to the AUX 1
to 6 mix. These are independent from the main mix and can therefore provide
additional outputs for monitors, effects, zone, recording feeds and so on.
AUX LEVEL Adjusts the level of the channel signal in each mix. Turn fully
anticlockwise to turn the signal off, fully clockwise for a maximum +6dB boost.
The normal ‘0’ position is marked. Each of the 6 aux mixes has its own
dedicated channel level control.
PRE/POST With the switch in the up position the post-fader channel signal is
routed to the mix. Press the switch to select the pre-fader signal instead. One
switch affects AUX 1-4, another AUX 5-6.
Set the switch to POST to send to external effects devices such as reverb
processors. The amount of signal sent to the device follows the fader level.
The processed (wet) signal returned to the mix elsewhere is therefore in
proportion to the direct (dry) routed signal regardless of fader position. Post-
fade sends are also used to provide zone or recording feeds where the outputs
should follow the fader movements.
Set the switch to PRE to send to monitors such as stage or remote foldback or
recording cue. The amount of signal in the monitor mix is independent of the
fader movements. therefore adjustments made to the main mix will not affect
the balance of the monitors. Note that selected channels in a monitor mix can
still be set post-fader if required, for example to prevent ‘dressing room’ talk
when working with radio microphones. The pre-fade sends are set post-EQ
post-ON as standard. These can be reconfigured pre-EQ and/or pre-ON by
resoldering internal links.
PAN Positions the channel signal between left and right in the stereo mix to
create the required image. The centre (mono) position is detented for quick
resetting.
ON Turns the channel signal on or off. The green LED lights when the channel
is turned on. All outputs except the insert send and PFL are muted when the
channel is turned off. Note that the pre-fade aux sends can be internally
reconfigured so that they are not affected by this switch if required.
PEAK The red LED lights when the channel is within 5dB of clipping. This
warns that you should turn back the GAIN control to reduce the signal level.
PFL Press PFL to listen to the pre-fader channel signal using the headphones
or local monitor. This does not affect the main outputs and lets you audition the
signal before you raise the fader and introduce it into the mix. The signal level is
also displayed on the console monitor meters so that GAIN can be set to
achieve the correct operating levels. The PEAK LED half lights to show which
channel PFL has been selected.
MIX 1 (2) Routes the post-PAN channel signal to MIX1 and MIX2. None, one
or both may be selected.
FADER A 100mm long throw fader adjusts the level of the channel signal and
provides a clear visual indication of its contribution to the mix. It does not affect
the pre-fader AUX sends. It does affect DIR OUT unless it has been
reconfigured pre-fader. The ‘0’ mark indicates normal operating position. The
fader can be set above or below this depending on the balance required in the
mix. A further 10dB of boost is available at the top of its travel. Use the PFL
system to check that the channel gain is correctly set before raising the fader to
add the channel to the mix.
