Cartridge downforce adjustment
The counterweight (6) supplied is suitable for cartridges weighing between 3,5 - 5,5g. Alternative
counterweights for cartridges weighing between 6 - 9g or 1,5 - 3g are available as accessory parts. Adjust the
downforce prior to installing the anti-skating weight.
Pushing carefully, turn the counterweight (6) onto the rear end of the tonearm tube (9), and so that the
downforce scale (6a) shows towards the front of the player. Lower the armlift and position the cartridge in the
space between arm rest and platter. Carefully rotate the counterweight (6) until the armtube balances out.
The arm should return to the balanced position if it is moved up or down. This adjustment must be done
carefully. Do not forget to remove the cartridge protection cap if fitted.
Once the arm is correctly balanced return it to the rest. Hold the counterweight (6) without moving it, and gently
revolve the downforce scale ring (6a) until the zero is in line with the anti-skating prong (15). Check whether the
arm still balances out.
Rotate the counterweight counter clockwise (seen from the front) to adjust the downforce according to the
cartridge manufacturer's recommendations. One mark on the scale represents 1 mN (= 0,1g / 0,1 Pond) of
downforce.
The recommended downforce for the factory fitted cartridge is
17,5mN
.
Anti-skating force adjustment
The anti-skating force must be adjusted according to the mass of the cartridge
as follows:
Downforce

Slip the loop of the anti-skating weight's thread over the third groove of the stub to set the correct anti-skating
force for the factory-fitted cartridge. Feed the thread through the loop of the wire support (17).
Connection to the amplifier
The record player has a captive tonearm signal lead (14) for connection to the amplifier. Use a line input (such as
AUX, CD, Tuner, Tape or Video) on your amplifier.
!
Due to the built in phono pre-amplifier, a phono input (sometimes labelled gram, disc or RIAA) is not suitable.
Take care to connect the left and right channels correctly. The right channel is usually marked red, the left
channel black or white. Check the manual supplied with your amplifier for relevant information. The earthing
wire of the tonearm lead should be connected to the earth terminal on your amplifier (if provided).
The 3,5 mm connector (supplied) can be used to connect your Pro-Ject Debut III/Phono SB to any line
level/auxiliary input (Computer, Midi System, Mixer etc.).
Connect the socket end to the phono plugs at the end of the audio trailing lead from your turntable and
insert the 3,5 mm plug into the relevant socket on your audio component.
Mains power connection
The turntable is supplied with a power supply suitable for your country's mains supply. Check the label before
connecting to ensure compliance with the mains rating in your house.
Connect the low voltage plug from the power supply to the socket (13) on the rear of the record player before
connecting the power supply to the mains.
Fitting the lid
Fit the lid (dust cover 10) carefully over the hinge prongs and adjust the screws (12) until the lid stays open
where you want it to without being too stiff to open or close.
