Set post-fade to create stereo recording feeds or to balance between
two effects devices such as reverb.
PRE
2k 5k 10k Press to select the channel pre-fader source, release for post-
fader. Auxes 1 to 4, 5 to 8 and stereo aux 9-10 are grouped for
pre/post switching. Pre-fade aux sends are not affected by the channel
fader movements. These are typically used to feed stage monitors.
Post-fade aux sends follow the channel faders and are typically used
to send a proportion of the channel signal to an effects device such as
reverb or delay. Note that post-fade sends may be preferred when the
console is configured in monitor mode so that the faders become
channel 'masters' affecting all monitor mixes.
PRE-EQ
to pre-insert, pre-EQ (switch pressed) so that inserted compressors
and the EQ do not affect the sends when mixing monitors from FOH.

This affects all auxes set pre-fader for the channel. The switch is
recessed to prevent accidental operation once set. Use a pointed
object to change the setting.
PAN
Positions the channel signal between L/R in the stereo mix,
and odd/even if routed to the groups. The centre position (mono
image) is detented for quick resetting.
MUTE
the feed to the LRM mix, pre and post-fade aux sends and direct
output, but does not affect the insert send. The red indicator lights
when the channel is muted. Always mute the channel when switching

phantom power or plugging the cables and sources.
PFL
Press PFL to listen to the pre-fade channel signal in the
headphones and local monitor without affecting the main outputs.
The console PFL/AFL active red indicator lights and the monitor LR
meters display the channel signal. Selecting more than one PFL at
the same time mixes those signals together in the monitor.
METER
'SIG' lights when a signal level of -12dBu is detected. '0' lights when
the nominal 0dBu level is reached, and '+6' at +6dBu. 'PK' lights
when the channel pre-fade signal is within 5dB of clipping. This gives
you enough warning to reduce GAIN before you hear signal distortion.

ROUTING
and the 8 groups. Use PAN to position the signal between L/R or the
odd/even group pairs. To route to a single group set PAN fully to one
side. Check that you have set these switches correctly before you start
mixing.
FADER

It also affects the direct output if this has been set to post-fade using
the internal option jumpers. The fader provides +10dB maximum
boost above its normal unity gain 0dB position.
