Dear music lover,
thank you for purchasing a PRO-JECT AUDIO record player.
In order to achieve maximum performance and reliability with this record player you should study these instructions
for use carefully.
Warning of a hazard for the user, the unit or possible misuse.
Important notice.
During assembly and adjustment of the deck small parts could be lost if not carefully placed in a suitable
Before starting assembly make yourself acquainted with the parts listed above and correspondingly numbered
in the technical drawings above. Separately packed items are marked with an asterisk *.
Safety instructions
AC outlet voltages vary from country to country. Before connecting to the mains, make sure that the
voltage in your area meets the voltage requirements printed on the power supply.
The power supply is used to disconnect the unit from the mains. Make sure that the power supply is
easily accessible at all times. Never handle the power supply while your hands are wet or damp.
Avoid letting liquids enter the device. Never place any item containing liquid, such as a flower vase
on or near the device. Never spill any liquid on the device. Never place any naked flame sources,
such as lighted candles on or near the device. The product shall not be used in damp or wet locations,
next to a bathtub, sink, swimming pool or any other similar conditions.
Keep plastic bags away from children to prevent any risk of suffocation.

The deck is supplied partially disassembled and carefully packaged for safe transport. Carefully remove all
parts from the transport packaging.
Screw the four feet (22) 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.
Carefully place the platter bearing housing over the bearing axle. Put the record weight on the platter and
level the plinth using a spirit level and the adjustable feet (22).
To adjust the feet, hold (A) and turn (B). Turning (B) clockwise decreases the height, turning anticlockwise
increases the height of the feet.
Fit the drive belt (3) around the platter (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.
Put the pulley cover on its rests.
Please note: 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:
left channel positive (L+)
right channel pos. (R+)
right channel return (R -)
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.
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 4 - 6g (counterweight no. 30),
5 - 8g (counterweight no. 46), 6 - 10g (counterweight no. 44) and 8 - 14g (counterweight no. 31). Alternative
counter-weights for cartridges weighing between 15 - 20g (counterweight no. 32) and 16 - 22g (counterweight
no. 33) are available as accessory parts.
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 stub (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
Please note: Adjust the downforce prior to installing the anti-skating weight.

Anti-skating force adjustment
The anti-skating force must be adjusted corresponding to the downforce as follows:
Groove in the stub (15)
10 - 14mN
1st from bearing rings
15 - 19mN
2nd "
20mN and bigger
3rd "
Hang the loop of the thread of the anti-skating weight in the groove of the anti-skating stub (15) corresponding
to the downforce applied to your cartridge and hang the thread in the groove of the wire support (17).
Adjusting the azimuth
The cartridge needle must be vertical in the record groove in order to trace the
groove wall modulations correctly.
A small screw at the bearing end of the arm allows incorrect azimuth to be
corrected if your needle is not mounted exactly perpendicular to the cartridge
body (which is often the case).
Slacken off the screw just enough to be able to revolve the arm tube without
applying force. Note! Do not remove the screw completely!
With the aid of a good magnifying glass adjust the needle until it is vertical in the groove (i.e. perpendicular
to the record's surface). Ideally this should correspond to the top surface of the cartridge body being parallel
to the record surface, but in practice this is often not the case.
When you are satisfied that the needle is vertical retighten the screw carefully.
Please note: Under no circumstances should the arm tube be adjusted with the needle still in the
record groove! Irreparable damage may be caused to the cantilever suspension! The arm must be
lifted to make each adjustment and lowered afterwards to check it.
Adjusting the vertical tracking angle (vta)
Put a record and the record weight on the platter. When the needle is lowered into the record groove and the
tonearm is not resting on the lift arm, the tube of the tonearm should be parallel to the surface of the record.
If it is not loosen both allen screws in the tonearm base just enough to allow vertical movement of the arm
pillar without force and slide the arm up or down until it is parallel.
Carefully retighten the allen screws without applying excessive force (which would deform the arm pillar) –
finger tight is quite sufficient.
Connection to the amplifier
Connect the tonearm cables to 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. An earthing
wire may be connected to the screw terminal on your amplifier you encounter hum problems when using the
record player.
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 which is then connected between the record player and a free line
level input of the amplifier.
For detailed product information regarding Pro-Ject Audio interconnect cables and phono amplifiers please
refer to the Pro-Ject web site
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 (1) on the rear of the record player before
connecting the power supply to the mains.
Fitting the lid
Fit the lid (dust cover 24) carefully over the hinge prongs and adjust the screws (23) until the lid stays open
where you want it to without being too stiff to open or close.

Maintenance and cleaning
Your record player requires little or no regular maintenance. Remove dust with a slightly moistened antistatic
cloth. Never use a dry cloth because this will create static electricity which attract more dust! Antistatic
cleaning fluids are available at specialist stores but must be applied sparingly to avoid damage to rubber
parts. It is recommended to fit the needle cover before cleaning or maintenance is carried out to avoid damage.
If the player is not used over a long period of time the drive belt can be removed to prevent unequal stretching.
Always disconnect the record player from the mains power supply as a precaution before maintenance!
