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.
