Adjustments and Fine-Tuning
Proper adjustments ensure the best sound quality and prevent record or stylus damage.
Setting the Tracking Force
- The tracking force is the downward pressure of the stylus on the record.
- Locate the counterweight at the rear of the tonearm.

- Consult the stylus manufacturer's recommended tracking force.
- Turn the counterweight dial to match this value, ensuring the stylus is applying correct pressure.
Adjusting the Anti-Skate
- Anti-skate counteracts the inward pull on the tonearm caused by friction.
- Locate the anti-skate control, usually a dial or slider near the tonearm pivot.
- Set it to match the tracking force value for optimal tracking and minimal record wear.
Setting the Pitch and Speed
- The Pioneer PL-7 features a pitch control slider, allowing fine adjustments to playback speed.
- To verify speed accuracy, use a strobe disc or a known reference record.
- Adjust the pitch slider until the strobe pattern appears stationary or the record plays at correct speed.
- The speed switch typically offers options such as 33 1/3 RPM and 45 RPM; select according to your record.
