AT-OC9XEN
The next Generation of the legendary OC9 cartridge series
Since 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. Featuring a square shank for accurate stylus alignment and nude diamond for increased fine detail retrieval.
- Features low mass nude elliptical stylus and aluminium cantilever
- A neodymium magnet and pure iron yoke provide increased magnetic energy
- Threaded inserts in the cartridge body enable the cartridge to be mounted on to the headshell or integral tonearm with just two screws – no nuts required
- Aluminium body minimizes unwanted vibration for reduced resonance and a superior audio reproduction
- Pure Copper by Ohno Continuous Casting process (PCOCC) is used for the coils to achieve the purest signal possible
Elliptical Nude Stylus
Elliptical diamond stylus follows the groove modulation with greater precision compared to a conical stylus, offering improved frequency and phase responses whilst reducing distortion.
Easy mounting
Threaded holes in the cartridge body enable the cartridge to be mounted on to the headshell, or integral tonearm, with just two screws M2.6 – no nuts or bolts required.
Aluminium Body
Aluminum body minimizes unwanted vibration for reduced resonance and superior audio reproduction
