Before beginning any service work, remove all power to the unit and disconnect any signal cables where
necessary. The rotating connector module must be set for desk top operation to gain access to the cover. Ensure
adequate lighting and use the correct tools.
Working from the front of the mixer remove screws and nuts (A) fixing the base cover to the front panel.

Locate Stereo input 13-14 circuit board assembly and Group 1 circuit board assembly. Referring
to fig.4 fit 2 x foam strips in between Stereo input 13-14 and Group 1 circuit boards. Remove the
IDC harness from the Right PCB all the way to Stereo input 13-14 PCB. Cut the TC buss wire
5mm from the component side of the Stereo input 13-14 circuit board assembly and bend the TC
buss wire vertically.
Slide the SYS-LINK circuit board in between the Stereo input channel and Group 1 circuit board
assemblies. Take care not to damage the ribbon harnesses already connected to the circuit
board.

Referring to fig. 1, fig. 5 & fig.6, form harness C as shown and prepare the solder pads on the
circuit boards with new solder to ease the soldering of the SYS-LINK wires.
Note, the wires are soldered to the trackside of the circuit boards and not the component
side.
It is recommended that the wires in the SYS-LINK harness are soldered to each circuit board in
the following order:
RIGHT PCB then LEFT then GROUP 4 then GROUP 3 then GROUP 2 and then finally GROUP
1 PCB.
