explain:The stylus is a consumable product with a normal service life of about 300-400 hours. In addition to damage caused by careless operation, excessive needle pressure, poorly made records, and severely shaky discs can all shorten the lifespan of the stylus tip. Due to the increased curvature radius of the worn out needle tip, its ability to track high-frequency signals in the sound groove decreases. When the details of the sound decrease, the high notes gradually deteriorate, and the sound becomes increasingly muffled, it is necessary to consider replacing the cartridge. Currently, most vinyl record players on the market use MM cartridge, and the Iron Triangle cartridge is basically universal. Just confirm whether it can be fixed to the boom. If the original machine also uses this cartridge, it will be even simpler, just remove the needle and replace it, without the need for the entire cartridge to be more compactChange.This Iron Triangle 3600L is a very cost-effective cartridge with over 50 years of production history and mature production technology. Due to the current trend of black glue, production and sales have been increasing year by year. What's even more rare is that as an entry-level cartridge for Iron Triangle, the material used for the cartridge needle has not been reduced, and the needle tip is made of extremely durable artificial diamonds. The needle rod is made of high-quality carbon fiber material, which not only strengthens the hardness but also ensures the sound level. Many big brand cartridge machines come standard with this cartridge or OEM methods. In short, with the current price of tens of yuan, it is truly unbeatable. Iron Triangle cartridge can be said to monopolize the hundred yuan level.Parameters:Audio Technica AT3600L Phono Cartridge Specifications-Output voltage: 4.2 mV-Frequency response: 20Hz-20kHz-Channel balance: 1.5dB-Channel separation @ 1kHz/10kHz Sound separation: 24/15dB-Tracking force needle pressure range: 2-2.5 g-Stylus type Needle tip type: Highly polished and shaped. 0006 inch conical diamond-Stylus construction stylus structure: Bonded round shank-Weight Net Weight: 5.7 g-Dimensions: 17,0 (H) x 16,3 (W) x 31,0 (L) mm Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
