The stylus is a consumable product with a normal service life of approximately 300400 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 record groove diminishes. When o details decrease, high frequencies become weaker, and sound quality becomes increasingly dull, it may be time to replace the cartridge. The stylus cantilever is made of high-quality material, enhancing rigidity and helping maintain consistent sound output. Output voltage: 4.2 mV. Frequency response: 20 Hz 20 kHz.
