4 XFADE ON. In the up position the music signal

is routed directly to the mix. Press to route the

signal through the crossfader.

5 XY. To route to the left (X) side make sure the

switch is in its up position. Press to route to the

right (Y) side. Either the green X led or yellow Y led

lights to show which side is routed. Both leds are

off if the signal is not routed through the crossfader.

6 XFADE PAN. Adjust to change the balance

between the left and right crossfader output signals.

Use this to correct an imbalance in the stereo

output, or as a dynamic performance effect. For

normal performance make sure the PAN control is

in its detented centre position.

7 XFADE to AUX send. This controls sends the

output of the crossfader to the stereo Aux mix. For

example, you could send the DJ music mix to a

monitor, zone, effect or special recording feed.

Replacing the Crossfader

The crossfader on a DJ mixer is heavily used and

can suffer considerable wear and tear. The audio

design using VCAs prevents clicks and scratchiness

as the fader wears. However, the movement can

become mechanically stiff or sloppy in time, or

become ingrained with dirt. Should this be the case

the fader may need replacement.

The XONE:62 crossfader is removable and can

easily be replaced in a few minutes. Make sure you

order the correct Penny & Giles version from your

Allen & Heath dealer: XONE2:XFADER

Use a medium size cross-point (Pozidriv)

screwdriver to undo and remove the two outer

screws on the crossfader plate. Do not remove the

inner screws. Lift the crossfader assembly up and

away from the console panel. Unplug the cable

from the old crossfader and plug in the new

assembly. Check that the connector is correctly

aligned and pushed on. Replace the assembly

making sure the cable faces the left side of the

console. Refit the screws and test operation.

The VCF Filters

A voltage controlled filter is an audio filter whose

cut-off frequency is altered by a DC control voltage

rather than a variable resistor. This produces a

much wider operating range and more control over

the filter response to create unlimited combinations

of tonal effect.

Each X and Y side of the crossfader is provided with

its own stereo VCF. Each can be switched in or out,

and each has its own frequency sweep control. The

filter type and resonance effect are globally selected

affecting both filters simultaneously.

8 FILTER ON switch. Each X and Y filter has its

own ON switch. The blue led lights when the filter is

switched on. The signal is not affected by the filter if

the switch is in its off position. Use this to punch the

filter effect in or out.

9 VCF SWEEP control. Each X and Y filter has

its own frequency sweep control to adjust the cut-off

point anywhere from low to high frequency.

Rotating the control during performance produces

the dynamic sweeping effects desired by performing

DJs. These large soft touch controls are positioned

either side of the crossfader for convenient live

operation. Separate controls for X and Y mean that

the effect can be applied to each track

independently and faded in as the crossfader is

operated. Note that the filter type and resonance

setting apply to both filters and are not

independently controlled.

10 RESONANCE control. Adjust this to change

the ‘Q’ or ‘sharpness’ of the filters. This affects how

they respond around the cut-off frequency. At the

minimum MILD setting the filters have a gentle roll-

off ‘knee’ giving a subtle, smooth response. At the

clockwise WILD setting they produce a resonant

feedback boost around cut-off resulting in some

very dramatic performance effects. The sound

varies according to the filter type selected. To avoid

unexpected results it is best to start experimenting

with RESONANCE set to a low position.

High RESONANCE settings can result in

significant boost of selected frequencies.

Reduce the channel GAIN if the signal levels

increase enough to light the red PK leds in the

output meters. Failure to do this may result in

system overload and distortion.
