TALKBACK, SIGNAL GENERATOR and MATRIX
TALKBACK
Individually assignable talkback is available to all the
main outputs. Plug in a suitable cable or gooseneck microphone. A
good quality dynamic or condenser vocal microphone is
recommended. Note that +48V phantom power is available at the XLR
as standard. If you prefer, this can be disabled by repositioning an
internal jumper link.
WARNING: Do not connect unbalanced sources or cables
to inputs with phantom power selected. To avoid loud clicks do
not press the TALK switch when plugging or unplugging the
talkback microphone.
First select the source you wish to talk to. You can select the auxes in
pairs, useful for communicating with the performers on stage. The four
groups are selected simultaneously, ideal for identifying a multitrack
recording. You can also talk to LR, ideal for announcements to the
audience. Once selected, press TALK to route the mic to the required
destination. Adjust the talkback level using the TRIM control below the
TB mic XLR.
SIGNAL GENERATOR / PINK NOISE
Press to select either
pink noise (up position) or a 1kHz sine wave tone as the test source.
Start with the trim control turned fully down. The generator ON switch
is rece ssed to prevent accidental operation. Press this with a pen or
pointed object. The green indicator lights to warn that the generator is
enabled.
The generator signal is routed to any source selected on the switch
bank above the TALK switch. Use the signal to test the loudspeaker
system and line up connected equipment. Pink noise is useful for
quickly testing the full range frequency operation and phasing/polarity
of loudspeakers. The 1kHz tone is better suited to lining up equipment
with its steady reading on the meters.
WARNING: We recommend you turn off the signal
generator once you have finished using it to test and line up your
system. This will prevent accidental operation during the show.
MATRIX
The matrix provides 2 additional console outputs. It is a
‘mixer within a mixer’ taking its source from the groups and main mix.
It can be used to provide duplicate main outputs or to create new
mixes from the main outputs. The controls are positioned conveniently
away from the live performance controls to avoid accidental operation.
Each of the 4 groups, L and R can be mixed independently into the
matrix. The source is derived post-fader. Adjust the level clockwise
from fully off to +6dB boost. Use the LEVEL control to adjust the
matrix output level from fully off to a maximum boost of +6dB. The
‘0dB’ positions are marked. The matrix output can be muted. The
post-level signal can be monitored using the AFL switch.
Use the matrix to create special mixes such as delay, fill and zone
speakers, recording and broadcast feeds, hearing assist loop and so
on.
