Replacing Xone:PX5 Faders

Print to PDF

Replacing the Faders

Channel and cross-faders subject to excessive ‘wear and tear’, or extensive use, over time will require replacing. Intermittent or noisy operation is an indication of faders becoming worn. Using a propriety fader cleaner, such as CaigLube, DeOxit, etc. may temporarily restore use, but DO NOT use on new faders as this can displace factory applied finishes.

REPLACING THE FADERS

IMPORTANT NOTES:

Warning! Please read the following steps in full BEFORE starting work.

If you are unsure of your ability to safely carry out the procedure described, it is advised that you contact an authorised Allen & Heath agent for local service assistance by a qualified technician. Please contact your mixer retailer, or local authorised Allen & Heath agent, for more information:

Ensure that the power switch on the rear panel is set OFF and that IEC mains cable is disconnected from

the AC mains supply BEFORE opening the unit.

Have a clean flat work surface ready before starting work.

Tools you will need:

  • T8 Torx screwdriver
  • Pliers
  • A small container for retaining screws

Ensure erroneous objects, such as cover screws etc. do not fall into the chassis or through louvres during disassembly, and check to make sure none are loose inside the unit BEFORE reassembling.

To replace Faders

ONLY use spare part components approved by Allen & Heath for replacement.
