Qu Mixer Reference Guide 30 AP9372 iss.8

The panel USB Select key in the SuperStrip switches

between the current Preamp source (Local or

dSNAKE) and the current USB source (Qu-Drive or

USB B). This key is not available on Qu-Pac.

Phantom Power

Turn on 48V if the connected device requires phantom

power, for example a condenser microphone or active

DI box. Touch and hold for 1 second to toggle on or

off. This prevents accidental operation.

 To prevent audible thumps make sure the channel

is muted before plugging or unplugging sources while

phantom power is on.

Gain

Turn up Gain so that the average loud signal reads

into the yellow of the meter. Turn down if any red peak

light flashes.

Polarity

Touch Ø to reverse the polarity of the input signal, for

example that of the lower mic when working with two

microphones on a snare drum.

Delay

Up to 85ms delay can be added to each input channel.

In most cases delay is not needed, but can be useful

in time aligning sound from the PA to the acoustic

sound from an instrument on stage. Allow 1ms per foot

distance as a starting point.

Touch and use the rotary to set delay time. Delay can

be switched in or out.

Insert

You can choose whether to insert either an FX or a

Ducker into the channel signal path. You cannot insert

both. Touch to highlight the selection knob and turn

the rotary to select FX or Ducker. The inserted device

can be switched in or out.

Inserted FX

Go to the FX / Back panel screen to choose and

assign one of the 4 internal FX as an Insert into a

channel. The FX is inserted after the preamp and

before the HPF.

Use the FX / Front panel screen to recall an FX Library

and work with the parameters. Touch the D/W control

and turn the screen rotary to balance between the

‘Dry’ (direct) and ‘Wet’ (affected) signal.

Inserted Ducker

The Ducker works by automatically reducing (ducking)

the level of the channel when a trigger source is

detected. For example, an announcement mic could

trigger the ducker on a music channel so that the

music level is reduced when an announcement is

made.

The Ducker is inserted between the HPF and noise

Gate.
