Master controls, solo/mute and fader
Towards the bottom of each input fast strip are the masters section and pan control,
LCD select button, mute and solo, and the input fader.
Masters sections and pan control
The masters controls have extensive support on both the control surface and the GUI.
In general, there are three routing switches to the master buses and also pan control.
Pan provides master panning as three-way or two-way (depending on SIS™ setting)
and also provides two-way panning for any stereo mix groups, subgroups etc. (When
used for monitor applications, aux, mix and main buses are controlled from the channel
master pan and fader. AFL solos also operate as a default from the main solo switch.)

Item Control Function
1 SIS switch This spatial imaging system (SIS) switch, enables
SIS™ mode. This mode operates with the pan and
mono level/SIS image control knobs, and acts as
an LCR master bus enable, overriding stereo and
mono master bus assignments. However, their status
remains in memory, so that when SIS is disengaged,
the mono and stereo settings can return. Pressing
SIS alters the gradations of the mono level/SIS
image control knob on the GUI.
2 ST switch This stereo switch connects post-fader channel signal
to master stereo bus via pan control.
3 pan control knob Adjusts the relative levels sent to a left-right bus pair
or the master left-centre-right (LCR) buses. In SIS™
mode, it can also control the ‘image’ to give a
constant power crossfade from LCR to stereo.
4 MON switch This mono switch connects post-fader channel signal
to mono master bus.
5 mono level/SIS
image control
knob
In mono mode, this dual-function control knob acts
as a mono level control knob to adjust the mono
signal level. In SIS™ mode, it becomes a SIS image
control knob that modifies pan control knob
operation to place the channel within a three-speaker
system (see “Stereo panning” on page 131).
