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.
LR FADER MASTER This 100mm stereo fader adjusts the main
L-R mix level. It provides +10dB boost above the nominal ‘0’ position.
For best performance the fader should be operated around the ‘0’
position for normal ‘loud’ level. If you find yourself operating
significantly below ‘0’ then the amplifier or other destination 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 fader 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 required 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 theatre. You may wish to feed just a few of the sources
to these speakers, for example 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 frequency 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 fader. 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.
