FB O
UTPUT
Provides a nominal 0dBu line level FB (Foldback)
mix. This is affected by the FB master fader but not
by the selected AB output configuration. The term
‘foldback’ is used because it folds back (returns) the
required mix to a loudspeaker positioned near the
performers on stage usually so that they can hear
their own vocals and a selection of instruments and
backing tracks. It can also, for example, be used to
provide a monitor to musicians in an orchestra pit or
to technical staff backstage. The foldback mix is
independent of the
LR mix. The signal from each
channel is derived pre-fader so that any changes
made to the fader position during performance do not
affect the monitor mix. The
FB mix can be
configured to the A or B amplifier channels.
Plug the FB output into an amplifier to feed the
monitor loudspeaker. Any loudspeaker suitably rated
for the amplifier may be used. Wedge shaped boxes
are preferred by many performers as they can be
positioned at floor level to direct the sound to the
performer. Alternatively, use a wired or radio in-ear
monitor where ambient sound needs to be reduced.
AUX O
UTPUT
Provides a nominal 0dBu line level auxiliary mix
output. This is affected by the
AUX master fader and
can be globally set pre or post the channel faders.
Note that the
AUX mix can be configured to the A
amplifier channel.
The AUX mix provides an ‘extra’ output that can be
used in many ways. For example it can be set pre
channel faders to provide a second foldback monitor.
It can be set post channel faders to feed a theatre
hard-of-hearing loop system, or delayed to feed fill
loudspeakers positioned to reinforce sound for the
audience seated far away from the stage. Here, the
signal should be delayed to match the acoustic delay
from the stage. The
AUX output can also be used post
fader as a send to an additional external effects
processor.
AB S
LAVE
O
UTPUTS
Provides a nominal 0dBu line level signal that
follows the mix configured to the
AB amplifier
channels. These outputs are not affected by the front
panel
AB level controls. They are affected by the 10-
band graphic equalisers.
These outputs can be used to feed additional
amplifiers to boost the output power of the system.
