Set-up

The deck is supplied partially disassembled and carefully packaged for safe transport. Carefully remove all
parts from the transport packaging.
Screw the two feet (23) onto the threaded bolts located on the underside of the plinth. Make sure the surface
you wish to use the turntable on is level (use a spirit level) before placing the turntable on it.
Remove the two red transport screws (1) which secure the motor (22) during transportation. Carefully place the

hub (4) bearing housing over the bearing axle. Level the plinth using a spirit level and the adjustable feet (23).
Fit the drive belt (3) around the hub (4) and the smaller diameter part of the motor pulley (2). Avoid getting
sweat or grease on the belt as these will deteriorate the performance and reduce the belt's lifespan. Use
absorbent kitchen paper to remove any oil or grease from the outer edge of the hub and the belt. Fit the
platter over the spindle of the hub.
Remove the transport lock (18) from the tonearm. Store it together with the two red motor transport screws
(1) in the original packaging so they are available for any future transportation.

We recommend to use the record player without a mat on the platter.

Fitting and connecting the cartridge

All cartridges with half inch mounting holes can be fitted. Leaving the needle's protection cover on, fit the

cartridge to the headshell using the screws supplied with the cartridge by passing one screw through each
slot in the headshell (21). Do not tighten the nuts yet.
Connect the tonearm wires to the cartridge pins as follows:
white

left channel positive (L+)

red

right channel pos. (R+)

green

right channel return (R -)

blue

left channel return (L -)

The full sound quality of the record player can only be achieved if the cartridge is correctly adjusted. Particular
tools like the PRO-JECT alignment tool are required to accomplish this job properly.
If you are not well acquainted with the adjustment of cartridges you are advised to call upon the willing help of

your PRO-JECT dealer to accomplish this task for you.

The finger lift (21) must be fitted on top of the headshell under the cartridge fixing bolts or nuts - not
between headshell and cartridge body.
Please note: adjusting a cartridge and tonearm calls for the greatest care in order to avoid damaging
the cartridge or tonearm bearings. Leave this work to your dealer if you are in any way unsure of the
necessary steps and precautions to be taken.

Cartridge downforce adjustment

The counterweight (6) supplied is suitable for cartridges weighing between 6 - 10g (counterweight no. 2).
Alternative counter-weights for cartridges weighing between 10 - 15g (counterweight no. 3), 9 - 11g
(counterweight no. 23) or 4 - 6g (counterweight no. 9) 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.
