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. Microlinear complex diamond profile enabling higher frequency response, detail like never before experienced and limiting inner groove distortion. Microlinear diamond profile provides low record and stylus wear.
Microlinear diamond profile offers high frequency response with less wear and distortion than elliptical or conventional linear contact styli.
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 Microlinear stylus almost exactly duplicates the shape of the cutting stylus that produces the original master disc (the disc used to create the pressed vinyl record). This likeness enables the Microlinear stylus to track portions of the groove other styli cannot reach, resulting in extremely accurate tracing of high-frequency passages and a flat frequency response within the audible range. The unique multilevel shape also wears more evenly, greatly extending record and stylus life.
