The stylus is a consumable product with a normal service life of approximately 300-400 hours. Damage caused by improper handling, excessive tracking force, low-quality records, or unstable turntable surfaces may reduce the lifespan of the stylus. As the tip's radius of curvature increases over time, its ability to track high-frequency signals diminishes. When audio details decrease, high frequencies become less clear and sound quality becomes duller, indicating the need for replacement. The stylus is constructed from high-quality materials to enhance durability and maintain consistent sound performance. Output voltage: 4.2 mV. Frequency response: 20 Hz - 20 kHz. Channel balance: 1.5 dB. Stylus type: Highly polished 0.0006 inch conical diamond. Stylus construction: Bonded round. Color: White. Material: Plastic. Package includes: 1 x Turntable Stylus.
