Replacing the Faders
The faders on a DJ mixer are 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:02 channel
faders and crossfader are 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.
Before you start make sure you turn off the console and disconnect the mains power
cord. The top plate must not be removed with power applied.
First prize off the fader knobs, take care whilst removing the EQ and Cue Mix knobs as they
are very tight. Excessive force can damage the fader assemblies. We suggest using the
edge of a plastic rule to prize the knobs off. Next, use a small cross-point (Pozidriv)
screwdriver to undo and remove the 8 top plate screws. Lift the plate off to gain access to
the fader assemblies. While supporting the fader with your fingers through the top opening
unscrew the two fader mounting screws. Remove the fader assembly out of the console
being careful not to damage any internal components. Unplug the cable from the old fader
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 front (channel fader assemblies) or
left side (Cross-fade assembly) of the console. Holding the new fader in position refit the
mounting screws. Replace the top plate and fit the fader knobs.
Make sure you replace the assembly with the correct fader type. Please note that earlier
models are supplied with the Alpha Crossfader.
Repositioning the Transform Switches
The CH1 and CH2 TRANSFORM toggle switches can be repositioned to reverse their
operation or rotate them to operate sideways.
Disconnect power and remove the console top plate as described above. Support the
toggle switch with your fingers through the access hole while removing the switch mounting
screws. Rotate the switch assembly into the new position required. Refit the screws into
the appropriate holes. Replace the top panel.
