The AB output routes to its TRS connectors through
a relay which is normally switched on.
switch may be wired to solder pads on the connector
circuit card to switch the relay off and isolate the
output. One application is in a broadcast studio
where a booth monitor should be muted when its
local mic is live. In this case the relay would be wired
to a micro-switch on the mic channel fader.
external switching, the relay could be wired to pins
on the REMOTE (user) port on the rear panel.
This option requires internal access to the rear
connector pod. Remove the two M3x6 Torx screws
from each side of the connector panel. Remove the
six M3x6 Torx screws from the rear of the connector
panel. Carefully tilt the connector panel away from
the console so that it is flat on the work surface.
Locate the GND, A and B solder pads on the solder
side of the connector circuit card. Pads A and B are
linked together with a small track. It is normal that
outputs A and B are switched simultaneously. To
switch the relays so that they isolate the output, wire
a switch from pad A to one of the GND pads. This
affects both the A and B outputs.
If you require separate switching of output relay A
and B then cut the interconnecting track and wire two
switches, one from pad A to ground, the other from
pad B to ground.
When the switch contacts are closed the relay
contacts will open, isolating the audio output from its
TRS jack connection.
