The Classic AT-OC9 - New & ImprovedSince its introduction more than 30 years ago, Audio-Technica’s pioneering moving coil OC9 cartridge series has been prized by demanding vinyl listeners and professional critics alike for its musical transparency, expression of sound and precise construction. Shibata profile diamond originally design for Quadraphonic replay offers a depth of sound, combined with high frequency response that has to be heard to be believed.
Scope of DesignThe AT-OC9XSH Dual Moving Coil cartridge with Shibata 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. Audio quality is further enhanced by a rigid aluminum body that reduces resonance, a neodymium magnet and premium permendur yoke that increase the magnetic energy, and the nude Shibata stylus on a boron cantilever that tracks the record groove with incredible accuracy, delivering rich, full-range audio and high transient response. The cartridge body has been pre-threaded, enabling it to be mounted to a headshell or integral tonearm with just two screws – no nuts required.
Features: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 Shibata stylus and boron cantilever for rich full-range audio reproduction 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
