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), 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 corresponding to the downforce as follows:

Slip the loop of the anti-skating weight's thread over the second 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 the Phono input 
(sometimes labelled gram, disc or RIAA) on your amplifier. Make sure that the phono input offers correct matching 
and amplification for the type of cartridge used. Line inputs (such as CD, Tuner, Tape or Video) are 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). 
If your amplifier does not have an input suitable for phono cartridges you will require a separate phono 
amplifier stage for MM or MC cartridges such as the Pro-Ject Phono Box or the Pro-Ject Tube Box which is then 
connected between the record player and a free line level input of the amplifier.

The recommended load resistance for the factory fitted cartridge is: 

47kohms

/

MM-input

 

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.
