ALLEN & HEATH Xone:22 Service Manual

ALLEN&HEATH Xone:22 service manual AP7528_3 Page - 7 - of 12
ACCESS
Tools required: T10 and a T8 Torx screwdriver.
1. Ensure that the power supply has been turned off and disconnected from the unit.
2. Using the T8 driver remove the three screws that are located in the centre of the channel
input and FX loop connectors (see illustration).
3. Using the T10 remove the 8 screws that hold the front panel to the chassis.
4. Now carefully lift the front edge of the panel up until the PCBs clear the chassis and pull the
whole assembly forward slightly until the connectors at the rear are free from the chassis.
You can now lift the front panel up to gain sufficient access to replace the faders or change
the jumper link settings. Reassembly is a reverse of this procedure.
5. Take great care to ensure that no harnesses become trapped and that all connectors are fully
pushed home. Replace the screws and test the mixer for correct operation.
