Talkback may also be routed to all the group buses and the stereo mix bus
simultaneously by the INT talkback function on this module; in this case the
Group/Stereo CUT and fader will affect the talkback level.
Output Switching
17
The PHASE switch reverses the phase of both left and right outputs. The
outputs themselves are electronically balanced at +4dBu, on male XLRs on the rear
panel.
18
The CUT switch mutes the signal to the left and right outputs. The switch has
an integral red LED which indicates when the signal is cut.

Wedge and Headphones Outputs
The wedge (operator's speaker) and headphones outputs share a common signal
source: when no PFL, AFL or LISTENs are active, then the source is either the
external PFL and AFL inputs, or the stereo mix signal, according to the position of
29
an internal jumper. The pupose of this jumper is to allow the wedge output to be
30
either quiet in the absence of any solo signals (preferred in monitor mixing
applications) or to monitor the stereo output in the absence of solo signals (preferred
for FOH mixing applications).
31
When a solo is active the signal is the console AFL or PFL signal, summed with
32
the external PFL and AFL signals.

The stereo wedge output level is controlled by the 100mm wedge Fader and
is balanced at +4dBu on XLRs.

The headphones output level is adjusted by the PHONES control ; the output
5 is available on a 1/4" 3-pole jack on the front panel.

21, 22
When the L switch is depressed, the Left signal is fed to both Left & Right
Wedge outputs. Similarly, when the R switch is depressed, the Right signal is fed
25
to both Wedge outputs. When the L and R buttons are both depressed, a MONO
mix of the Left and Right signals is fed to both Wedge outputs.

Mute Masters
20
21 24
The four, latching, Mute Master buttons M1 - 4, which each have an integral
22 red LED, control the four mute buses. Any inputs assigned to a mute bus will be
cut by the appropriate mute master, except those on which the SAFE switch has
been pressed.
24
Using the Solo System
A solo system of pre-fade listen (inputs) and post-fade listen (outputs) feeds the
23
operator's wedge/'phones outputs.
Normally, all active AFL, PFL and LISTEN signals are summed together and fed
to the wedge or phones outputs.
