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 the following instructions: Place the stylus pressure gauge onto the platter.

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!

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 (14) using the screws supplied with the cartridge by passing one screw through each slot in the headshell (14). 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 “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.
  • The 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 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 a loose plug/socket connection.
  • Phono input not selected at the amplifier.
  • An amplifier is not switched on.
  • Amplifiers 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 an amplifier, or earth loop.

Distorted or inconsistent sound from one or both channels:

  • The record player is connected to the wrong input of the amplifier, or the MM/MC switch is incorrectly set.
  • Needle or cantilever damaged.
  • Wrong r.p.m., drive belt overstretched or dirty, platter bearing without oil, dirty or damaged

Service

  • Should you encounter a problem that 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.
