Groups allow up to 8 separate mixes to be created and recorded on the multitrack in
addition to direct signals from the channels. Each group has a 12 segment bargraph peak
reading meter, mono/stereo switching configuration, AFL monitoring and 100mm faders.
Sometimes it is necessary to control more than one channel simultaneously, for example a
drum kit or a group of backing vocalists. This is known as subgrouping. Route the channels
to groups instead of L-R, using the channel routing switches and pan controls. PAN selects
the required group or positions the signal in the stereo image of a pair of groups.
It is normal to set up mono or stereo subgroups using the channel PAN controls and the
group L-R and STEREO switches.
The post-fade signals of the groups may be fed to the main mix L & R busses as follows:
STEREO – In the up position the groups are routed in mono to L-R. Press this switch in
association with the L-R switches below to separately route the group signal to the L or R
mix busses, L routes the odd groups e.g. 1, 3, 5, 7 and R routes the even groups e.g. 2, 4,
6, 8. This provides a stereo subgroup to L-R.
L-R – press this switch to route to the L-R mix e.g. selecting the L (left) switch of the L-R
switch pair and with the STEREO switch in the up position, the group signal will route to
both left and right mix busses. With the STEREO switch pressed, the group signal will route
to the left mix buss only.
AFL (After-Fade Listen) routes the post-fader signal to the L&R meters, the control room
speakers and the headphones and allows checking of the sound quality and mix level. If the
STEREO switch is pressed, the AFL signal will only be heard in the left or right channel
only, depending on which group has AFL selected. Pressing a pair of AFL switches allows
monitoring in stereo. If the STEREO switch is not selected then the same AFL signal will be
heard in mono.
Group fader - 100mm smooth action fader controls the overall group level. The group
outputs are routed via the GRP/DIR switches on the I/O channels to the channel Tape
outputs. Note, groups 1 to 8 outputs are duplicated on the tape outputs of I/O channels 9-16
and also on channels 17-24 and 25-32. Thus group 1 output is on the TAPE OUT jacks of
channels 1, 9, 17 and 25 when the GRP/DIR switch is pressed.

Each aux mix has a master level control that adjusts the output level to match external
equipment, or to trim the effects level without affecting the mix balance. The nominal output
level is –2dBu with an extra +10dB of boost if required. Aux 1 & 2 are switchable pre/post-
fade sends and 3, 4, 5 & 6 are post-fade for effects processing.
LINK – press this switch to route the aux 1 mix to aux 3, ideal for accessing a common
effect unit such as a reverb unit from both the channel path and monitor path during
mixdown.
PRE/POST GLOBAL SELECT – In the up position, the aux send is fed from the channel
Pre-Fade aux mix. Press this switch to configure Aux 1 (2) as post-fade. Normally, effects
sends are post-fade, so that the effect follows the fader level and cue feeds are Pre-Fade
so that an independent mix can be sent to the musicians.
AUX – use this control to adjust the aux output level from off to +10dB.
AFL (After-Fade Listen) routes the post aux mix signal to the L&R meters, the control room
speakers and the headphones and allows checking of the sound quality and aux mix level.
The same AFL signal will be heard in both channels.
TALK – press this momentary switch to talk to the aux mix using the built-in microphone.
MUTE - This turns the Aux 5 (6) mix signal on or off. This mute can be controlled by the
automation system. This is very useful for automated effects muting.
