Setup and Installation
Proper installation is crucial for optimal performance. The cartridge comes with free mounting bolts for secure attachment to your turntable's headshell.
Installation Steps:
- Power Off: Ensure your turntable is powered off and unplugged from the mains electricity before beginning installation.
- Remove Old Cartridge (if applicable): Carefully disconnect the wires from your old cartridge and unmount it from the headshell. Note the color coding of the wires for correct re-connection.
- Connect Wires: Connect the four color-coded wires from the tonearm to the corresponding pins on the new MAG cartridge. Typically:
- Red: Right Channel (R+)
- Green: Right Channel Ground (RG-)
- White/Blue: Left Channel (L+)
- Blue: Left Channel Ground (LG-)
- Mount Cartridge: Using the provided mounting bolts, securely attach the MAG cartridge to your turntable's headshell. Do not overtighten.
- Align Cartridge: Proper cartridge alignment (azimuth, vertical tracking angle, overhang) is essential for accurate sound reproduction and to prevent record wear. Refer to your turntable's specific manual for detailed alignment procedures.
- Set Tracking Force: Adjust your turntable's counterweight to set the tracking force. The recommended tracking force for this cartridge is 3.0g (within a range of 2.5g to 3.5g).
- Anti-Skate Adjustment: Set the anti-skate mechanism on your turntable according to the recommended tracking force.

Operating Instructions
Once installed and properly aligned, your MAG cartridge is ready for use. Always handle your turntable and records with care to ensure longevity and optimal sound quality.
- Record Placement: Place your record gently on the turntable platter.
- Cueing: Use the cueing lever to carefully lower the tonearm onto the record's lead-in groove. Avoid dropping the tonearm manually, as this can damage the stylus or record.
- Playback: Allow the record to play. The diamond stylus will track the grooves, converting vibrations into electrical signals for amplification.
- Ending Playback: At the end of the record, use the cueing lever to lift the tonearm and return it to its rest.
Maintenance
Regular maintenance of your stylus is essential for preserving sound quality and extending the life of both your cartridge and your records.
- Stylus Cleaning: Gently clean the stylus tip before or after each play using a soft stylus brush, moving from back to front. Never brush from side to side or front to back, as this can damage the cantilever.
- Record Cleaning: Keep your records clean to prevent dust and debris from accumulating on the stylus.
- Stylus Inspection: Periodically inspect the stylus for wear or damage. A worn stylus can cause poor sound quality and damage your records. Replace the stylus if it appears bent, chipped, or excessively worn.
