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.  
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: counterweight (6), anti-skating weight (16) platter (5) and belt (3). Fit the 
cartridge protection cap. Insert the transport lock for the tonearm (18) prior to carefully packaging the record 
player.
