The Master Section
AUX MASTERS Each aux mix has a master level control that adjusts the
output level to match external equipment, or to trim the monitor, effect or other
send without affecting the mix balance. Up to +4dB boost is available above the
normal 0dB position.
Note that the AUX5 and AUX6 master controls do not affect the level sent to the
internal effects processor. They do affect the level available at the rear panel aux
output sockets.
LR FADER MASTERS Individual faders adjust the main L-R mix level.
They provide +10dB boost above the nominal ‘0’ position. For best performance
the faders should be operated around the ‘0’ position for normal ‘loud’ level. If
you find yourself operating significantly below ‘0’ then the amplifier or other desti-
nation equipment is too sensitive for the console +4dBu output. Simply turn
down the amplifier or equipment level trim. If none is available then insert an
attenuator pad between the console and connected equipment. Operating the
faders well below ‘0’ may degrade the noise performance of the equipment.
M FADER MASTER A recessed mode switch above the M fader selects
the fader source.
Mono master To use the M output as an L+R summed mono feed then select
the up position. The fader can become the master level controller for a mono PA,
mono fill or delay speaker, additional zone, mono recording and so on.
Aux master To use the M output as the AUX6 master press the switch using a
pen or pointed object. Use the post-fade AUX6 channel sends to mix the re-
quired signals to the M output. This provides a main console output with its own
mix bus. Typical applications include:
Dedicated MONO mix The output feeds a centre mono fill speaker system,
for example above the proscenium arch or along the front of the stage in a thea-
tre. You may wish to feed just a few of the sources to these speakers, for exam-
ple just the radio mic channels for front row clarity. Using the aux send allows
you to create the required mix balance and have proper master fader control.
Aux fed subs This increasingly popular application drives the sub bass speakers
with their own mix. It lets you send only those sources with wanted low frequen-
cy information to the sub speakers. It can dramatically clean up the mix as non-
bass channels such as vocals and guitars are kept out of the subs and therefore do
not allow low frequency pickup to muddy the mix. It is typical to include only
sources such as kick drum, bass guitar, keyboards and sound effects to these
speakers.
The unique MixWizard aux mode feature puts the master control of the sub mix
on to a fader next to the main LR faders. This means that the house volume can
be controlled without upsetting the balance between LR and sub speakers. The
feed to the sub speaker system is on balanced XLR, and it can be monitored by
selecting the M switch in the headphones monitor section.
