- Rosso: Canale destro attivo (R+)
- Verde: Terra del canale destro (R-)
- Bianco: Canale sinistro caldo (L+)
- Blu: Terra del canale sinistro (L-)
3.2 Installing the Stylus
The stylus is typically pre-installed. If you need to install the spare stylus or replace an existing one:
- Gently hold the cartridge body.
- Align the new stylus with the front of the cartridge body and push it firmly but carefully into place until it clicks securely. Avoid touching the stylus tip.
3.3 Setting Tracking Force (Downforce)
The recommended tracking force for this cartridge is da 1.0 a 1.5 grammi. Refer to your turntable's manual for instructions on how to adjust the tonearm's counterweight and anti-skate settings to achieve the correct tracking force. Proper tracking force is essential for sound quality and to minimize record wear.
4. Istruzioni per l'uso
Once installed and properly adjusted, your AT Cartridge is ready for use. Always handle your turntable and records with care.
- Before playing a record, ensure the stylus guard is removed.
- Place the record on the platter and ensure it is clean.
- Abbassare delicatamente il braccio sul solco d'ingresso del disco utilizzando la leva di avanzamento. Evitare di far cadere il braccio direttamente sul disco.
- After playback, use the cueing lever to lift the tonearm and return it to its rest. Replace the stylus guard to protect the stylus when not in use.
5. Manutenzione
Regular maintenance will prolong the life of your stylus and ensure consistent sound quality.
5.1 Pulizia dello stilo
- Clean the stylus regularly to remove dust and debris. Use a soft stylus brush, brushing gently from back to front (in the direction of the tonearm pivot). Never brush from side to side or front to back.
- For stubborn dirt, a specialized stylus cleaning fluid can be used sparingly with a stylus brush.
5.2 Sostituzione dello stilo
The stylus is a delicate component that wears out over time. A worn stylus can damage your records and degrade sound quality. Replace the stylus after approximately 500-1000 hours of playback, or sooner if you notice a significant drop in sound quality or increased record wear. Refer to section 3.2 for replacement instructions.
