10.8 The FX
Qu features 4 internal stereo FX (effects) processors. Each can be loaded from a library of different effects
types and presets. These are the same as found in the flagship Allen & Heath iLive digital mix system and
are based on emulations of popular industry standard effects.
The FX screen
Press the FX key next to the Touch Screen to open the
FX screen. You work with the FX in the same way you
would with a traditional outboard rack. Start with an
empty rack as shown here. Each of the 4 FX has a
rack slot. Touch the tabs at the top to select each slot.
Library – Press the Fn key to open the Library page.
Select Factory or User library and scroll through and
select the FX type you wish to load into the rack. The
effects are arranged in types on the left with available
presets for each in the right hand window. Touch
Recall to load the FX.
Listen to and experiment with the different presets and
their parameters available.
FX types
Reverb – This is the most popular effect in live sound
mixing. The SMR Live (Spatial Modelling Reverberator)
features 4 fully configurable spatial models - Classic,
Hall, Room and EMT plate. Each of these use different
reflection and decay algorithms to add natural
sounding space to the dry signal whether subtle small
room echo, vintage vocal plate or a massive arena.
Reverb can make a vocal sound spacious and smooth
in the mix or add body to an instrument such as
acoustic guitar or flute. There are plenty of factory
presets available. The 4 buttons at the top control the
main parameters if you wish to make adjustments. HF
and LF cut shape the response, and Expert opens up
a host of parameters for fine control if you wish to
experiment further. You also have the 4-band PEQ
available in the FX Return channel processing.
Delay – Generates separate left and right tap delay
outputs from the input. Delay time can be dialled in
using the screen rotary, tapped on screen or tapped
using a SoftKey. The left and right delay taps can be
linked to produce a mono effect. Feedback adds
regeneration for a repeating echo effect. Set a short
delay time around 80 to 160ms for the classic
slapback effect.
ADT - An Automatic Double Tracking module capable
of creating short echo/chorusing, classic double
tracking and ‘slapback’ tape delay loops. It includes a
stereo width enhancer and auto panning within the
stereo field. The ADT is perfect for creating classic
doubling effects, thickening programme on stage or
developing a stereo sound field as an alternative to
chorusing.
Chorus - Chorus derives from the late 80’s where
different stereo field creation techniques influenced the
sound of each chorusing unit. Chorus recreates the
classics using 3 stereo-field emulations. These
emulations can be switched in any combination
creating many different stereo fields.
