Audio-Technica AT-OC9ML/II Dual Moving Magnet Cartridge

Audio-Technica AT-OC9ML/II Dual Moving Magnet Cartridge

The Audio-Technica AT-OC9ML/II is a high-performance stereo phono cartridge designed for detailed, accurate, and engaging vinyl playback. Featuring a Dual Moving Coil (MC) design, it is engineered to deliver precise channel separation, excellent musical detail, and a wide frequency response of 20–30,000 Hz.

The cartridge uses a nude elliptical stylus with a 0.3 × 0.7 mil profile mounted on an aluminum pipe cantilever. This stylus configuration is designed to accurately follow the record groove and reproduce fine musical information with clarity and precision. The AT-OC9ML/II provides a 0.32 mV output and 25 dB channel separation, making it suitable for high-quality MC-compatible phono systems.

Built with an aluminum body, the AT-OC9ML/II combines a rigid construction with carefully engineered internal components to support stable and accurate analog playback. Its 1.8–2.2 g tracking-force range, with 2.0 g as the standard setting, allows proper groove tracking when correctly matched and aligned with a compatible tonearm.

The AT-OC9ML/II is designed for use with MC-compatible phono preamplifiers or head amplifiers and has a recommended load impedance of 100 ohms or higher when connected to a head amplifier. Its threaded M2.6 mounting holes provide a secure installation on compatible headshells and tonearms.

With its Dual Moving Coil architecture, nude elliptical stylus, aluminum cantilever, and precision-oriented construction, the Audio-Technica AT-OC9ML/II is a strong choice for vinyl enthusiasts seeking refined stereo reproduction and detailed analog performance from their turntable system.
