GROUP / AUX 1-8 and AUX 9-12 MASTERS
AUX/GRP MODE. This switch reverses the group
fader and aux rotary master sections. It is
underpanel to protect it from accidental operation.
Use a pen or pointed implement to select the
required setting. The default up position is flush
with the panel.
In the up position FOH MODE is selected. This is
the default setting for the front-of-house application.
In FOH mode the fader master section and insert
are associated with the audio group while the rotary
master is associated with the aux send.
In the pressed position MONITOR MODE is
selected. This reverses the fader and rotary master
so that the fader master section and insert are
associated with the aux send while the rotary
master is associated with the group. The group
always feeds the matrix and sub grouping to main
mix regardless of mode.
AUX ROTARY MASTER. Adjusts the aux master
output level from fully off to a maximum boost of
+6dB. The normal ‘0’ position is marked. This
becomes the group master when MONITOR mode
is configured.
AFL. Press this switch to listen to the master signal
in the headphones or engineers monitor without
affecting the main outputs. The signal is monitored
post-level so that the signal feeding the connected
equipment can be checked. The same capabilities
apply as described for the fader master AFL.
MAIN MIX. A single switch routes each group 1-8
signal to the 3 output main mix. Select this to create
up to 8 subgroups to the main mix. Its balance and
image within the L, R and C outputs is determined
by the BLEND and PAN controls. The group
always feeds this sub grouping to main mix
regardless of mode.
BLEND. This control adjusts the balance between
the LR and C outputs. Fully anti-clockwise all the
signal routes to the LR outputs and none to C. At
the detented centre position the signal routes
equally to the LR and C outputs. Fully clockwise all
signal routes to the C output and none to LR. The
control has a 3dB attenuation at centre position.
PAN. Adjusts the balance between the L and R
outputs. It does not affect the C output. At the
detented centre position the signal routes equally to
L and R. PAN and BLEND combine to adjust the
balance between the 3 outputs. The control has a
3dB attenuation at centre position.
