Using the Crossfader 
The crossfader is the one feature that instantly sets the DJ mixer apart from a conventional mixer. It lets you 
smoothly fade from one track into another using a single fader. It is also used as a creative performance tool to 
layer or interact between two sounds when cut or scratch mixing . A high grade dual rail fader with long lasting 
gold contacts is used. The ultra high quality Penny & Giles type can be fitted as an option if preferred. 
The  XONE:32 uses four high performance voltage controlled amplifiers (VCAs), a pair for each side of the 
stereo crossfader. The robust 45mm fader produces a DC control voltage which determines the signal level of 
the VCAs. The voltage is filtered to prevent any audible noise, clicks or scratchiness resulting should the fader 
track become worn. This benefit would not be possible if the signal were routed through a conventional audio 
fader. Using the fader as a controller also means that its response can be easily tailored to suit the mixing style. 
CH1 feeds the left ‘X’ side of the crossfader so that all the signal is routed when the fader is at its fully left 
position. CH3 feeds the right ‘Y’ side of the crossfader. CH2 does not feed the crossfader. Instead, it routes 
directly to the mix. The OFF switch lets you disable the crossfader so that it does not affect the channel levels.  
Select this when your mixing session does not need crossfading. The front panel green LED lights when the 
crossfader is on and extinguishes when it is off. 
Use the CONTOUR control to adjust the way the fader responds as you move it. You can adjust from a very 
gentle fade with 6dB dip in the middle suitable for smoothly fading in one track as the other fades out, to a very 
sharp response where the signal reaches full level within a few millimetres of the start of travel, suitable for fast 
cut or scratch mixing. The middle position provides a standard constant power fade where the volume remains 
the same as you fade from one track to the other. 
Use the REVERSE switch to swap the X and Y sides of the crossfader so that CH1 feeds the right hand Y side 
and CH3 feeds the left hand X side. Use this function if it better suits your mixing style. 
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:32 crossfader is removable and can easily be replaced in a few minutes. There are 
two versions available, the standard type and the higher grade Penny & Giles type. Make sure you order the 
correct version from your Allen & Heath dealer. 
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.
