that are assigned to grand master vca B will be summed onto the solo busses when the vca solo is
active.
Note i. When grand master vca B solo switch is active the PFL buss also receives signals but they
are NOT a true representation of the relative levels within the grand master vca sub group. This
feature is however useful as it allows confirmation of signal present and signal quality when the
grand master vca fader is down or muted. It is therefore important to know the status of the PFL
MONITOR switch on the COMMS module before using the grand master vca solo switches.
Note ii. If a grand master vca solo switch is pressed for a short time it will latch on or off, but if it
is held on for more than 1 second the latching is disabled and when the switch is released the solo
will turn off.
2. The ISOlate B switch disconnects the grand master vca B sub group faders and mutes from
automation screen recall. Screen storage is still active.
3. The vca MUTE B switch mutes any AUDIO group post fader signals which are assigned to the
grand master B vca sub group.
4. The grand master B VCA GROUP fader is motorised and under automation control. It gives
continuous adjustment of the grand master vca sub group gain from +10dB to off.
XL422 Matrix Pod.
1. The CHANGE OVER switches change the function of the left and right meters so that they
monitor the stereo aux send outputs in place of the matrix outputs.
2. The METERS monitor the peak signal level of the matrix or stereo aux outputs as described
above but when the GLOBAL METER CHANGE OVER switch on the COMMS module is
activated the meters monitor the matrix bus or stereo aux bus amplifiers (which ever is selected).
XL441 Matrix Module.
1. The STEREO AUX MASTER control gives continuous adjustment of the stereo aux output
level from + 10dB to off.
2. The stereo aux MUTE switch mutes the stereo aux outputs.
3. The stereo aux SOLO switch sends stereo aux signals to the PFL mono and AFL stereo busses.
If the switch is pressed for a short time it will latch on or off, but if it is held on for more than 1
second the latching is disabled and when the switch is released the solo will turn off.
4. The MTX switch sends the pre fader stereo aux bus signals to the matrix mix directly below so
that the console can be used for monitor applications.
5. The MIX controls (1 to 16) give continuous adjustment of the audio sub group levels sent to
the matrix mixes from + 6dB to off. If the FADER CHANGE OVER switch on the GROUP
module is active the aux bus will route to the matrix mix in place of the audio sub group.
6. The GLOBAL PRE ON switch changes the audio sub group signals that are routed via the mix
