7.8 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.
