Internal options
N.B. Internal settings should be undertaken by skilled personnel only
Remove the top case cover by removing 6 screws located at the sides of the unit and 2 screws located on the top of
the unit. (Re-assemble in the reverse order)
Refer to drawing 860PCB (towards the back of the manual) for positions of internal options.
Mains Voltage
The CX4 MkIII has been designed to operate on 220-240Vac or 110-120Vac. A slide switch located on the PCB
behind the mains input connector selects the operating voltage. The voltage selected is displayed on the switch
230 (220-240V) 115 (110-120).
DAMAGE MAY RESULT IF THE UNIT IS CONNECTED TO THE WRONG SUPPLY VOLTAGE
Fuses
Mains fuse sizes are 250mA anti surge for 220-240V operation and 500mA anti surge for 110-120Voperation. It is
important for safety reasons that the correct fuse sizes are always used.
Phantom Power
If phantom power is required for the priority microphone it may be selected on a jumper located rear left edge of the CX4
looking from the front panel. Legend on the PCB indicates setting.
Priority input selector
The priority input selector is located behind the priority in/out sockets - two jumpers select mic or line input. A label
showing the jumper positions is provided. (Be sure to move both jumpers)
The factory setting is for a Microphone input.
Earth lift
A jumper is provided to lift the audio common (0VE) from mains earth. This may be necessary in some
installations. A skilled audio system specialist should determine if this is necessary, otherwise this should be left in
the factory supplied or normal position.
Limiter time constant
As described in the noise limiter section a jumper is provided to allow some adjustment to the limiter speed. This
jumper is located towards the left center of the PCB viewed from the front and is clearly labelled.
