Service manual

12. The AUX I/P MUTE mutes every aux line return input on the GROUP modules.

13. The INS LEFT and RIGHT switches connect the master left and right insert return signals to

the stereo master mix.

14. MATRIX SEND PRE. Feeds to the matrix modules from the stereo busses are post fader as a

default. When the MATRIX SEND PRE is active, the feed changes to pre fader and pre insert.

15. The BALANCE (pan) control gives continuous and reciprocal adjustment of the stereo left

and right signal levels by + 3dB to off. This allows fine adjustment of the left, right power levels

and imaging.

16. The stereo master MUTE switches mute the stereo master outputs but not the insert sends.

These switches are under automation control.

17. The stereo master SOLO switches send stereo master 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.

The master mix signal can not be sent to the solo busses while any other solo is active. This means

that they can be left on to provide a stereo master signal in the headphones which will be overrid-

den if any other solo is activated on the console.

18. The stereo MASTER FADER gives continuous adjustment of the stereo master mix level

from + 10dB to off.

XL413 Grand Master A VCA Fader.

1. The grand master A vca SOLO switch is used to monitor the grand master A VCA sub group

by creating a corresponding AUDIO sub group on the stereo AFL busses. All AUDIO sub groups

that are assigned to grand master vca A will be summed onto the solo busses when the vca solo is

active.

Note i. When grand master vca A 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 A switch disconnects the grand master vca sub group faders and mutes from

automation screen recall. Screen storage is still active.

3. The vca MUTE A switch mutes any AUDIO group post fader signals which are assigned to the

grand master A vca sub group.

4. The grand master A 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.
