Group Output Module
Talkback
10
The momentary TB switch feeds the signal from the TALKBACK
MICROPHONE to the group output; it is independent of the Fader position and the
CUT switch. The existing group output is dimmed by 6db, and the engineer's
wedge speaker is dimmed by 20dB while the TB switch is active.
Talkback may also be routed to all the group buses simultaneously by the INT
talkback function on the master module; in this case the group CUT and fader will
affect the talkback level.
Metering
11
The group output level is metered by an integral peak-reading 16-segment
LED bargraph which is situated next to the Fader; the meter is calibrated for 0 at
+4dBu output. An internal jumper allows the meter response to be set to
average-reading instead of peak-reading.
Solo
12
The electronically latching AFL switch, which has an integral amber LED,
feeds the post-fade, post-insert group signal to the engineer's wedge speakers and
phones output; however, if INPUT PRIORITY (see the Master Module) is enabled
then any active input PFLs will replace the AFL signal, and the group will not be
heard until the inputs are un-PFLed. If solo AUTO CANCEL (see the Master
Module) is selected, then the AFL will cancel any other active PFLs or AFLs. The
AFL may also be cleared with the Master Module's SOLO CLEAR function.
13
The PRE INSERT switch moves the AFL signal before the insert point.
14
The AFL TRIM control gives +/-10dB of level adjustment.
