SERVICING AND JUMPER SETTINGS
To change the Phono input to line
Remove the front panel as outlined before.
You need to locate and remove the two black
jumper links on the input PCBs in the location
shown. It is a good idea to leave the jumper links
attached to one pin so that they can be refitted at a
future date.
Remove these two jumper links (JP1 and JP2) for
each channel that you want to convert to line.
How to replace the channel faders or crossfader
If the faders, especially the crossfader, are subject to a lot of use they will, in time, wear out and need replacing. Inter-
mittent or noisy operation is an indication that they are becoming worn. Using a propriety fader cleaner such as
CaigLube might temporarily restore them, but DO NOT use on a new fader as it will wash away the factory applied
grease.
Warning! Dismantling your mixer could invalidate the warranty; if you are unsure of your ability to safely carry out this
work then it is advised that you leave it to a qualified service technician.
Tools you will need are a T10 and a T8 Torx screwdriver. Ensure that the power supply has been turned off and dis-
connected from the unit. Using the T8 driver remove the three screws that are located in the centre of the channel
input and FX loop connectors (see illustration). Using the T10 remove the 8 screws that hold the front panel to the
chassis. 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.
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.
