ALLEN & HEATH Qu-32 Reference Guide

Qu Mixer Reference Guide 34 AP9372 iss.9
Insert switches an internal FX in or out if one has been
patched into the mix. The button is disabled when the
insert is not patched. The FX is inserted at the start of
the processing before the EQ.
Use the FX / Back panel screen to choose and assign
one of the 4 internal FX as an Insert into a mix.
Groups allow FX or Ducker to be inserted. Using the
Ducker on a Group provides a quick way to set up
multiple channel ducking as well as providing master
processing and control for those channels. The ducker
works in the same way as that described for input
channels above.
GEQ (graphic equaliser)
The Graphic EQ is a popular tool for tuning out
resonant frequencies in PA systems, for example when
ringing out monitor speakers.
The GEQ allows tonal adjustment of the overall mix
sound. It splits the 20Hz to 20kHz audio frequency
range into 28 standard 1/3 octave bands from 31.5Hz
to 16kHz allowing +/-12dB cut or boost.
Touch the screen In button to switch the GEQ in or
out. Touch a slider to highlight it and use the screen
rotary to cut or boost its frequency. This affects a
small range of frequencies 1/3 octave wide centred on
the frequency marked below the slider. The position of
the sliders shows the approximate shape of the
resulting frequency response curve.
GEQ Fader Flip (Qu-16, 24 and 32)
Press the surface GEQ Fader Flip key to view and
adjust the GEQ on the faders while a mono, stereo or
the LR mix is selected. The screen highlights the active
range of frequencies. Press the switch again to
change range or return to normal mix mode.
The faders toggle between the lower and higher
ranges of frequencies with a useful overlap. The
frequencies are shown on screen and marked on the
panel above the faders.
The fader strip Sel key turns on when the slider is at
0dB mid (flat) position while in fader flip mode. Press a
Sel key to return a slider to 0dB.
The strip meters display the RTA of the current PAFL
signal. The dominant frequency (peak band) lights the
red meters. Select the mix PAFL key to view its RTA.
It is better to cut rather than boost frequencies when
tuning speakers using the GEQ.
