1、 ALLEN Mono Fader, Master Fader Centre, Master Fader L/R & Control Panel. 1) Cut the 2x Cable ties attaching the Stereo Slave PCB onto the Mono Fader & Control Panel PCBs. 2) Carefully remove the Stereo Slave PCB by pulling it upwards. 3) Once removed, turn the Stereo Slave PCB over. 4) To remove a

2、PCB, use a 5.5mm spanner to remove the relevant M3x4 Taptite Hex Headed Screws that attach the PCBs to the Master Fader bracket. 5) To remove a fader, remove the two relevant M3x5 Countersunk Pozi Screws with underhead pips (H) as shown in fig.4. Then unplug the fader wireform from the Stereo Slave

3、PCB, the fader can now be removed. De-solder the three fader wireform wires from the fader, taking note of the wire positions for refitting. 6) Removal of the H shaped Control Panel PCB can only be achieved once the vertical section of PCB has been removed. Once the vertical section has been removed

4、, remove the 2x M3x6mm Pan Pozi Black screws attaching the H shaped Control Panel PCB to the fader bracket. The H shaped Control Panel PCB can then be removed. 10) To remove the Mute Group PCB, use a 5.5mm spanner to remove the two screws attaching the PCB to the fader bracket. The VCA Master Slave

5、PCB must be removed before the Master Fader PCBs can be removed. 11) Cut the 2x Cable ties attaching the VCA Master Slave PCB onto the Master Fader PCBs. 12) Remove the 15way Flexi cable running between the VCA Master Slave PCB and the Mute Group PCB. 13) Carefully remove the VCA Master Slave PCB by

6、 pulling it upwards. 14) Once removed, turn the VCA Master Slave PCB over. 15) To remove a PCB, use a 5.5mm spanner to remove the relevant M3x4 Taptite Hex Headed Screws that attach the PCBs to the Master Fader Bracket. 16) To remove a fader, remove the two relevant M3x5 Countersunk Pozi Screws (H)

7、from the Master Fader front panel (see fig.4). Unplug the fader wireform from the Stereo Slave PCB, the fader can now be removed. De-solder the three Fader wireform wires from the fader, taking note of the wire positions for refitting. Note: A fader can be removed without removing the IDC wireforms

8、and Slave PCB. 17) To refit any of the PCB assemblies, follow the above procedure in reverse order. Make sure all harnesses are aligned and plugged on. Test for correct operation.

9、 the unit and disconnect any signal cables where necessary. Ensure adequate lighting and use the correct tools. Before you can access the internal PCB assemblies, invert the console and remove the screws securing the base in place. Carefully lift the base off. Note that the Earth Strip has been remo

Ensure adequate lighting and use the correct tools. 1) Remove the screws attaching the relevant Earth Strip running the length of the Mono section (see fig.6, right hand section only shown) then lift away the Earth Strip. 2) C

12、arefully detach the 50way IDC wireform from the Mono Input PCBs and the SYS-LINK II Input PCB as far as the relevant Mono Input PCB. Note: There are two different 50way IDC wireforms on either side of the Master section. Remove the relevant IDC wireform according to the side on which the particular

13、Mono Input PCB lies. 3) Remove all the knob and switch caps from the required Mono Input PCB, then remove the pot nuts underneath using an 11mm nutdriver. 4) The required Mono Input PCB can now be removed from the console. 5) To refit a Mono Input PCB assembly, follow the above procedure in reverse

14、order. Make sure all harnesses are correctly aligned and plugged on. Test for correct operation. fig.6 SYS-LINK II PCB Earth Strip 50 way IDC wireform ML5000 Service Manual 31 Removing the Master Distribution PCB assembly To access the Group and Auxiliary PCB assemblies it may be necessary to remove

15、 the Master Distribution PCB. Before beginning any service work, remove all power to the unit and disconnect any signal cables where necessary. Ensure adequate lighting and use the correct tools. 1) Before removing the Master Distribution PCB assembly, the console base must first be removed. 2) Loca

16、te the Master Distribution PCB assembly positioned near the centre of the console (see fig.7). 3) Unplug all attaching IDC wireforms from the Master Distribution PCB assembly. 4) Desolder the Earth wire from the PCB then carefully remove the Master Distribution PCB by pulling it away from the consol

17、e. 5) To refit the Master Distribution PCB assembly, follow the above procedure in reverse order. Use an inspection mirror to check that each connector and IDC harness is correctly aligned and plugged on. Note: If a switch is fitted to the rear of the Master Distribution PCB rather than solder links

18、 then make sure that it is set correctly. Test for correct operation. fig.7 Master Distribution PCB Earth wire LCR Option links or switch 32 ML5000 Service Manual Servicing the Meterbridge Assembly Before beginning any service work, remove all power to the unit. Ensure adequate lighting and use the

19、correct tools. 1) Remove all the plastic snap-in rivets along the face of the meter panel with your fingernails or other non-abrasive tool. 2) With a person standing at either end of the console, each using a small, thin screwdriver, place the screwdriver through each of the endmost bottom rivet hol

20、es (see fig 8). Raise the meter panel up with the screwdrivers so that the bottom becomes free of the extrusion. 3) The complete meter panel assembly can now be removed from the meter pod extrusion by pulling it away from the extrusion, bottom first (see fig.9), allowing access to the Meter PCB asse

At regular intervals, it is recommended that the foam fan filters are cleaned or replaced to ensure efficient operation of the power unit. Fai

22、lure to do so may reduce the efficiency or even damage the power unit. To remove the fan filters, switch off and disconnect all power to the MPS14. Remove the rack ears and place to one side. Remove the cover fixing screws and cover and place to one side. The foam fan filters can now be removed by s

23、imply sliding out of the slots. Either clean or fit new filters depending on their condition. Replace the filters and reassemble the power unit. Check the fans are running unobstructed before completely re-installing. Replacing the mains fuse The AC mains fuse is located on the rear of the MPS14 uni

24、t next to the AC mains connector. In the event of a mains surge or under-rated fuse value, the mains input fuse will rupture. Switch off the power supply and remove the mains lead plug from the “MAINS INPUT” socket on the rear of the unit. Check the fuse and replace if necessary. TO AVOID THE RISK O
