AUX SENDS
GROUP 5-8 are available on balanced
XLR outputs to drive long cable runs,
and with INSERTS to insert signal
processing devices such as
compressor/limiters into the signal
path. Use these outputs as additional
speaker feeds or for recording. In
'MONITOR MODE' these become
AUX 5-8 outputs to provide a total of
8 dedicated stage monitor sends on
XLR and with inserts.
All the XLR outputs operate at a
nominal high level +4dBu. Ensure
correct matching to external
equipment.
SUBGROUPING
Using subgroups lets you group similar
sounds together under control of a
single fader (mono subgroup), or
panned pair of faders (stereo
subgroup). For example, the mics on a
drum kit (kick, snare, overheads, toms),
backing vocals, stage mics, orchestral
wind section etc.
Select L-R ON to route a group to L-R
as a subgroup. Position the signal
within the stereo image using PAN.
This illustration shows sub 1-2 as a
stereo pair, and sub 3-4 panned off
centre to slightly close the stereo image,
useful when the speaker stacks are
widely spaced and the front rows of the
audience may be confused by a full
stereo image. The subgrouping is
always fed from the group mix
regardless of GRP/AUX REVERSE.
AUX 5-8 jack outputs to
send to selected signals
to external effects
devices. A nominal
control setting of '7'
allows +10dB boost
above normal line level.
MODE
SWITCHES
AUX 1-4 balanced outputs
to feed foldback monitors.
INSERT graphic EQ to tune
out acoustic resonances to
minimise feedback. AFL lets
you check the output signal
after the insert and master
level control.
MONITORS
GROUPS
EFFECTS
Decide your required
console configuration and
set these recessed
switches using a pen tip
or similar.
Press REVERSE to swap
the group fader section
with the aux master
section. This represents
'MONITOR MODE' where
the aux mix is controlled
on the fader with output
METER, AFL, balanced
XLR and INSERT for full
control of the monitor
mix. AFL lets you listen
to and check the effect of
the inserted graphic EQ
or similar processing
device.
In this mode the group
mix is available on the
aux master controls to
feed the jack outputs, as
well as the subgroup
section.
Mix and match this fader
section as you require.
For example you could
have 2 as monitor sends,
4 as subgroups, and 2 as
additional outputs.
