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.
