CX-A200 I

NSTALLATION AND OPERATION MANUAL

12 Field Servicing

The CX-A200 is ruggedly built and uses proven reliable circuitry. It requires no more than

the occasional removal of any dust that may have built up inside the unit as a result of the

forced cooling. In the unlikely event of failure, the power amplifier module (4 channels)

complete with power supply components and input circuitry can be replaced without

special tools and is available as a tested replacement assembly complete with heatsink.

Proceed as follows to replace the power module:

Disconnect all the leads and connectors from the rear of the unit.

Ensure that the mains supply lead has been disconnected.

Remove the CX-A200 from the equipment rack.

Remove the top panel.

Remove the 10 way ribbon cable and the four spade terminal which connect the

transformer. Disconnect the red and black fan supply wires.

Remove the VCA modules (if fitted) complete with the mounting spacers.

Remove the eight fixing screws from the input connectors and the two fixing screws from

the output connectors. Now remove the PCB fixing screws and carefully remove the PCB

Now fit the replacement unit by proceeding in reverse order.

No setting up is required and the unit should operate normally.
