AFL
This allows after fade (post fade) signals to be heard on the monitors and viewed on the main
stereo meters.
Auxiliaries
Sometimes known as auxiliary sends these are used as secondary mix buses. The mixes created
on these buses are then used to feed eect units or are fed back to the performers as a foldback
feed. Every channel has access to the auxiliary mixes and the contribution of any channel can
be varied by using the appropriate auxiliary level control. Auxiliaries can be switched pre or post
fader and be allocated to either the SF or LF signal paths.
Auxiliary Master
Associated with every auxiliary there is an auxiliary master control to give overall level control
rather than having to adjust the contribution from every channel.
Bus Master
Inputs are assigned to bus outputs through a routing matrix, enabling one or many inputs to be
assigned to the same bus. The bus outputs usually correspond to inputs on the DAW or other
recording device. Each bus then has a mixing amplifier whose gain can be controlled by the Bus
Master Trim. This allows the level to a multi-track input to be raised or lowered without having
to adjust the individual level of each channel routed to that track. The faders can still be used to
adjust the relative levels of channels.
Cut
The cut or mute control is used to silence (mute) a signal path when it is not in use. This removes
the noise contribution from that source leading to a quieter mix. There are cut switches in both the
SF and LF signal paths.
Dim
This allows the control room loudspeaker levels to be reduced by a pre-set amount. Dim will be
brought into action automatically when talkback is used preventing howl round.
