Group Output Module
Talkback
8
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 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.
Output Phase
9
The PHASE switch, which has an integral red LED, reverses the phase of the
group output. The group output itself is electronically balanced at +4dBu, on a male
XLR on the rearcon.
Metering
10
The group output level is metered by an integral peakreading 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.
External Input
An external input, from an XLR on the lower rearcon, may be added to the group
bus. The input is balanced with a sensitivity of +4dBu.
11
The EXT IN control adjusts the level of the external signal to the group, it
provides a maximum 10dB gain when it is fully clockwise.
12
The latching ON switch activates the external input. An integral green LED
indicates when it is on.
13
The latching LSTN (Listen) switch, which has an integral amber LED,
provides a pre-fade, pre-ON solo to the 'phones or wedge output. LISTEN is not
affected by the AUTO CANCEL or SOLO CLEAR functions, and overrides any
output AFLs if INPUT PRIORITY is active.
