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 not switched on.
Amplifier or speakers 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.
Service
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 effected if the unit is returned correctly packaged. For this reason, we recommend
keeping the original packaging.
