Aux

Here you’ll find knobs that control the levels of aux sends A and B. AUX A is either pre-fader or post-fader, depending on the position of the PRE / POST switch. When the switch is in the raised position, the aux send is pre-fader. When the switch is depressed, the aux send is post-fader.

What does all this mean? In POST mode the aux send is affected by the fader, EQ and HPF settings. In PRE mode the aux send is affected only by the EQ and HPF settings. POST mode is generally used for sending the signal to an external effects device (so that the fader controls the signal level), and PRE mode is usually used for cue sends (for example, sending a signal to headphones while recording, for which you may not want the fader to alter the channel’s level).

AUX B is always post-fader, as indicated by the word “POST” to the right of this knob. Like AUX A, AUX B can be used for routing signals to external devices. And when you are using the onboard effects processor, AUX B is used to control the level of the channel’s signal being routed to the processor.

The MultiMix gives you three bands of EQ per channel. Using these knobs, you can tailor the channel’s signal by boosting some frequencies and cutting others. The LO and HI controls are shelving controls with fixed frequencies of 80 Hz and 12 kHz respectively. The MID control has a peaking response fixed at 2.5 kHz.

“Shelving” means that the mixer boosts or cuts all frequencies past the specified frequency. “Peaking” means that frequencies above and below the specified frequency fall off, forming a peak in a graphical representation.

Master Section

The Master Section is the heart of the mixer, where the channel inputs and aux returns all are mixed together and routed in various ways.

Main Mix Fader

The signals from all channels and aux sends—excluding those that are muted—are sent to the main mix. The MAIN MIX fader is the one you’ll use to control the overall level of those combined signals. This fader affects the levels of the signals sent to the
