2.3 Tonearm Balance and Tracking Force

After mounting, it is essential to balance your tonearm and set the correct tracking force.

1. With the stylus guard on, adjust the tonearm counterweight until the tonearm floats freely and level.
2. Set the tracking force dial (if present) to zero without moving the counterweight.
3. Adjust the counterweight or tracking force dial to the recommended tracking force. For the MAG M27BS, the recommended tracking force is 3.0 grams. The acceptable range is 2.5 to 3.5 grams.
4. Set the anti-skate control to match the tracking force setting.

3. Operating Instructions

Once installed and properly adjusted, your MAG M27BS cartridge is ready for use. Always handle your records and stylus with care to ensure longevity and optimal sound quality.

• When finished playing, use the cueing lever to lift the tonearm and return it to its rest.

4. Maintenance

Regular maintenance will help preserve the life of your stylus and maintain sound fidelity.

• Stylus Cleaning: Periodically clean the stylus tip using a soft stylus brush, brushing gently from back to front (in the direction of play). Do not brush side-to-side. Specialized stylus cleaning fluids can also be used sparingly.
• Cartridge Body: Keep the cartridge body free from dust. Use a soft, dry cloth to wipe it clean.
• Stylus Guard: Always engage the stylus guard when the turntable is not in use or when moving the tonearm to prevent accidental damage to the stylus.
