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.
Elliptical diamond stylus follows the groove modulation with greater precision compared to a conical stylus, offering improved frequency and phase responses whilst reducing distortion.
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.
Aluminum body minimizes unwanted vibration for reduced resonance and superior audio reproduction
Produced in the Audio-Technica Fukui factory in Japan under strict quality control for precise manufacturing.
The purpose of a stylus is to ride along the record groove capturing movement, which is then transferred into an electrical signal within the turntable cartridge. Audio-Technica produces styli in five different shapes (Conical, Elliptical, Microlinear, Shibata, and Special Line Contact) that make contact with the record groove and capture movement in different ways, creating unique sound characteristics.
The elliptical stylus has two radii, the front radius being wider than the side radius. The front radius rides in the centre of the groove like the conical, while the smaller side radius makes more contact with the groove walls. Increased contact with the record groove walls delivers a higher level of fidelity for your sound system.
