5、qualified service personnel only. Mains power is dangerous and can kill. Do not attempt to work on a linear or switched mode power supply if you are not suitably qualified to do so. Do not attempt to repair surface mount circuit assemblies unless you are suitably qualified and have the necessary fac

6、ilities to do so. Replacement circuit assemblies can be ordered. Service facilities: Ensure a suitably sized work surface is available. Ensure this is clear of dirt, debris and obstructions which may damage the equipment surfaces. Ensure adequate lighting. Use the correct tools for the job and ensur

7、e they are in good working order. Ensure all workshop safety requirements are adhered to. Service information: Check that you have all the information you need before starting the service job. Refer to the Allen & Heath web site or contact Allen & Heath technical support for details on the latest in

8、formation. Full technical information can be downloaded from the web site Distributor Zone (password required). Mains power: Connect the equipment to mains power only of the type described in the user guide and marked on the rear panel. The power source must provide a good ground connection. Ensure

9、you always use an isolation transformer when working on any mains power supply unit. Mains cord and fuse: Use the correct power cord as supplied with the equipment. Do not remove or tamper with the ground connection in the power cord. Heed the Important Mains Plug Wiring Instructions printed in the

10、user guide if it is necessary to rewire the mains cord. Always replace the equipment mains fuse with the correct type and rating as described in the user guide and marked on the equipment panel. Opening the unit: Switch off and remove the mains power cord before opening the equipment. Ensure all pow

11、er supply covers and safety shields are in place before applying power with the unit open for diagnostic fault finding. Closing the unit: Before finishing, check the quality and accuracy of the service work carried out. Remove any dirt or debris as this may cause equipment failure in the future. Ens

12、ure all assemblies, harnesses and connectors are correctly aligned and plugged in. Ensure that jumper settings and control configurations are correctly set according to the requirements of the customer. Testing the unit: Before operating the equipment, read and adhere to the Important Safety Instruc

13、tions printed in the user guide. Test that the service work has been successfully carried out. Shipping the unit: Use adequate packing such as the original packaging or purpose designed flight case if you need to ship the unit. To avoid injury to yourself or damage to the equipment take care when li

14、fting, moving or carrying the equipment. Servicing Notes XONE:92 User maintenance: There are several user configurable jumper links inside. These are described in the user guide together with instructions on how to change the default settings. Technology: The XONE:92 uses SMT (surface mount) PCB tec

15、hnology. In certain cases it may be better to replace a faulty assembly rather than try to fix it without the appropriate tools and training. The power supply is a built-in universal mains input, switched mode circuit which should be serviced by suitably qualified personnel only. Operation: The XONE

16、:92 is a performance club mixer. To ensure optimum performance and reliability it should be connected and operated as described in the user guide. Fault finding: Refer to the system block diagram and circuit drawings to follow through the signal path during fault diagnosis. Replace suspected faulty

17、components only with those specified by Allen & Heath. The use of lower grade alternatives may degrade the performance. Ensure the RCA phono insert jumper links are pressed fully in if fitted.

This operation should only be carried out

25、 by qualified service personnel. IMPORTANT! Disconnect mains input lead before removing the top panel Removal of the top panel requires the use of a Torx T10 screwdriver. Use a good quality tool to prevent rounding the screw heads. First remove the 4 pipped TORX screws located on rear panel in the c

26、enter of each block of input channel RCA (Phono) connectors, and then undo the 8 M3 x 8 screws that hold the front panel to the chassis. Lift the front edge of the top panel until the two filter PCBs are clear of the chassis, and then pull the top panel gently forward and up until access can be gain

27、ed to unplug the power cable from the power supply located on the right hand side of the chassis. Continue to lift the front edge of the top panel up until it is possible to unplug the two harnesses from the rear connector PCB. Lift the top panel clear of the base and place on a clear work surface.

28、Reassembly is the reverse procedure, but take great care to fit the harnesses correctly and to ensure that the ribbon cables do not get trapped between any of the PCBs and the chassis. Refit the panel screws first and tighten evenly with the chassis held firmly on a flat work surface. Finally refit
