Allen&Heath Qu-16 - Manual (Page 44)

Qu Mixer User Guide 44 AP9372 iss.4
Symphonic Chorus - A faithful emulation of the 80’s
classic chorus effect. Simple to use and frequently
requested. The unit has just two controls, Frequency
and Depth controlling the rate and delay range of the
stereo modulator. The unit produces a rich, lively and
wide chorus sound with a suggestion of very mild
phasing / flanging. Live engineers commonly use this
for thickening vocals and strings and creating a spatial
sound from a mono source. This has led to two factory
presets ‘SymphonicVox’ and ‘SymphonyStrings’.
Flanger – Qu provides three classic flanger effect
emulations – ‘Ambient’, ‘Vintage’ and ‘Wild’. During
research of classic pedal flangers we found numerous
LFO modulators and stereo splitting techniques. We
implemented them all. For classic deep flange set
Stereo Split and Stereo Spread off, pick triangular
modulation, Vintage type and adjust Depth and
Regeneration.
Phaser - A classic 12 stage emulation producing rich
textured phasing with plenty of control. You can
control the number of stages, feed forward and feed
back, and ‘zero’ depth manual mode to manually
sweep the Phaser using the offset control.
Gated Verb- An accurate emulation of the popular 80’s
Gated Reverb plus two other variants called ‘Panned’
and ‘Powerbox’. The user interface gives instant
access to Lo-cut Hi-cut decay spectrum filters and the
gate envelope controls - predelay, attack, hold and
release.
Patching the FX
Touch the top right tab to select the Back Panel view.
Open the option list to select the type of FX patching.
Touch
Apply to confirm any changes:

Mix>Return – Known as a ‘system effect’ this
uses a bus to Send a mix of the channels to the
effect, and a dedicated stereo FX Return channel
to add the ‘wet’ effect to the ‘dry’ original sound.
This is used for effects such as reverb and delay.
Choose which mix bus to use as its input. For the
Qu-16, FX1 and FX2 have dedicated buses. If you
want to use FX3 or FX4 as another system effect
you could patch one of the Mix1-10 buses as its
input.

Ch>Return – This is similar to a Mix>Return
system effect but fed from one channel rather than
a mix of channels. It uses the assigned input
channel Direct Output as its source. Examples
include a vocal channel delay, gated verb on a
snare, or chorus added to guitar.

Insert – Here the effect is patched in line with an
input channel or mix master. It is switched in or
out using the channel Insert switch. Inserted FX
provide a Dry/Wet control to balance the effect
with the original signal.
