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 tip. As the tip's radius of curvature increases over time, its ability to track high-frequency signals in the groove diminishes. When o details decrease, high frequencies degrade and sound becomes dull, it may be time to replace the stylus. The stylus body is made of high-quality material, enhancing durability and ensuring consistent sound performance. Output voltage: 4.2 mV. Frequency response: 20 Hz - 20 kHz. Channel balance: 1.5 dB.
