AUX SENDS
GROUPs 5-8 are available on
balanced XLR outputs to drive long
cable runs.
INSERTS are provided
on all 8 groups 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 ', GROUPs 5-
8 become AUX 5-8 outputs to provide
a total of 8 dedicated stage monitor
sends on XLR with inserts.
MUTE
switches the signal off . Muted
groups are indicated by red LEDs.
AFL
lets you check the output signal
after the insert and fader control.
Each group has 4 way LED metering
providing signal presence indication
and peak warning which illuminates
approximately 5dB before clipping.
The subgrouping is always fed from
the group mix regardless of
GRP/
AUX REVERSE .
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 .
AUX 5-8 jack outputs to
send selected signals to
external effects devices.
MODE
SWITCHES
AUX 1-4
balanced outputs
feed foldback monitors with
graphic EQ on
INSERT
to
tune out acoustic resonances
or 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 on the fader with
METER , AFL , MUTE,
balanced XLR output 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.
These PAN settings show subgroup 1-2 as a stereo pair, and
subgroup 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.
