Qu Mixer Reference Guide 30 AP9372 iss.9
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.
