The Group fader is fed with the Group mix signal via
the Group Insert point. The fader has 100mm of
travel and there is +10dB of gain at its maximum
position.

Group AFL
The AFL switch allows monitoring of the Group
signal after the fader but before the Mute switch.
signal after the fader but before the Mute switch.
Group Mute
The illuminated Mute switch cuts the Group signal
from the Group output, sub routing and the Group
meter.
The Group signal to the Matrix outputs is also cut
with the Mute switch.

meter.
The Group signal to the Matrix outputs is also cut
with the Mute switch.
Group Meter
A 4 LED bar meter to show the level of signal on
the Group output.
The thresholds are:
Sig = -18dB nominal, 0dB, +6dB, Pk=+16dB.
0dB on the meter = +4dBu at the balanced output.

The thresholds are:
Sig = -18dB nominal, 0dB, +6dB, Pk=+16dB.
0dB on the meter = +4dBu at the balanced output.
Group Pan
The Pan controls how the Group signal is shared
between the Left & Right main mix buses when sub-
routed. The Group output is unaffected by the Pan
control.
between the Left & Right main mix buses when sub-
routed. The Group output is unaffected by the Pan
control.
Group Sub Routing
The L-R switch routes the panned Group signal to
the main LR mix and the M switch routes the un-
panned Group signal to the mono bus.
If you want to set up a stereo pair of sub-groups and
route them to the main LR mix, make sure the odd
numbered Group is panned Left and the Even Group
is panned Right.
