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 m6dB boost.
The normal ‘0’ position is marked. Each of the 6 aux mixes has its own
dedicated channel level control. The stereo left and right signals are mixed
together to produce a mono sum that feeds the aux mix. This may be changed
by resoldering internal links so that all pre and/or post-fader sends are
configured in stereo with left signal feeding odd numbered auxes and right
feeding even.
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-ON by changing internal
links.
BAL
Adjusts the relative left and right levels in the stereo mix to create the
required balance. This becomes a PAN control if the channel is operated in
mono. The centre 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 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 (in mono) 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-BAL 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. The ‘0’ mark indicates normal operating position. A
further 10dB of boost is available at the top of its travel.
