Cartridge downforce adjustment
The counterweight (8) supplied is suitable for cartridges weighing between 3 - 7g (weight no. 81). The
counterweight is pre-set perfectly from the factory.
In case you need to set the tracking force, please read following instructions:
Place the stylus pressure gauge onto the platter. To adjust the amount of pressure, carefully move the
counterweight along the support rod, until the stylus pressure is sufficient to raise the pressure gauge
to the level position. Moving the counterweight away from the cartridge will reduce pressure and
towards will increase pressure. Finally secure the counterweight using hexagonal key provided.
If the stylus gauge becomes level, then the correct pressure has been achieved. However if the there is
insufficient or excessive pressure the gauge will either not move or tilt down.
Take care to connect the left and right channels correctly. The right channel is usually marked
red, the left channel black or white.
The red speaker terminals carry the positive signal (+), the black speaker terminals the negative
signal (–). Make sure the polarity of the connection is correct at each end of the cables.

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
Always disconnect the record player from the mains power supply as a precaution before
Mounting 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 (12) using the screws supplied with the cartridge by passing one
screw through each slot in the headshell (12). 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 “Align IT” 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.
Useful tips
The record player should be positioned on a low-resonance surface such as wood or multiple layer ply
board to avoid structural vibrations disturbing replay.

Potential incorrect use and fault conditions
Pro-Ject turntables are manufactured to the highest standards and undergo strict quality controls
before leaving the factory. Faults that may possibly occur are not necessarily due to material or
production faults but can sometimes be caused by incorrect use or unfortunate circumstances. Therefore
the following list of common fault symptoms is included.
The platter doesn't turn although the unit is switched on:
The unit is not connected to the mains power supply.
No mains at the socket.
Drive belt is not fitted or has slipped off.
No signal through one or other channel or both channels:
No signal contact from the cartridge to the internal tonearm wiring or from that to the arm lead or
from that to the phono box or between that and the amplifier. This could be due to a faulty plug,
broken wire or solder joint or simply loose plug/socket connection.
Phono input not selected at amplifier.
Amplifier is not switched on.
Amplifier or speakers are defective or muted.
No connection to the loudspeakers.
Strong hum on phono input:
No earth connection from cartridge or arm or arm cable to amplifier, or earth loop.
Distorted or inconsistent sound from one or both channels:
Record player is connected to wrong input of amplifier, or MM/MC switch incorrectly set.
Needle or cantilever damaged.
Wrong r.p.m., drive belt overstretched or dirty, platter bearing without oil, dirty or damaged
Should you encounter a problem which you are not able to alleviate or identify despite the above
information, please contact your dealer for further advice. Only when the problem cannot be resolved
there should the unit be sent to the responsible distributor in your country.
Guarantee repairs will only be affected if the unit is returned correctly packaged. For this reason we
recommend keeping the original packaging.
Never return a record player without making sure that is it safely disassembled and correctly packaged
in the original packaging according to the diagrams on the last page of this user guide. Please remove
these parts and pack them separately: lid, counterweight (4), anti-skating weight (10) and belt (22).
Fit the cartridge protection cap and the transport lock for the tonearm tube (66), prior to carefully
packaging the record player.
The manufacturer accepts no responsibility for damage caused by not adhering to these
instructions for use and/or by transportation without the original packaging. Modification or
change to any part of the product by unauthorized persons, release the manufacturer from any
liability over and above the lawful rights of the customer.
