The AT-OC9XSL Dual Moving Coil cartridge with special line contact stylus is designed to provide outstanding channel separation. The Pure Copper by Ohno Continuous Casting (PCOCC) coils ensure pure audio transmission and are aligned in a reverse V-shaped formation to exert less pressure on the stylus, thereby minimizing distortion Dual Moving Coil design, featuring independent coils for both left and right channels, provides outstanding channel separation The coils are aligned in a reverse V-shaped formation, which exerts less pressure on the stylus, thereby minimizing distortion The cartridge body is pre-threaded, enabling it to be mounted onto the headshell or integral tonearm with just two screws – no nuts required Features nude Special Line Contact stylus and boron cantilever with accurate tracking ability and high transient response A neodymium magnet and permendur yoke provide dramatically increased magnetic energy Aluminum body minimizes unwanted vibration for reduced resonance and superior audio reproduction Pure Copper by Ohno Continuous Casting process (PCOCC) is used for the coils to achieve pure signal transfer
