Audio-Technica AT33xMONO/I Dual Moving Coil Mono Cartridge

The Audio-Technica AT33xMONO/I is a true-mono dual moving coil phono cartridge engineered to reproduce monaural vinyl with outstanding focus, clarity, and quiet. Part of the acclaimed AT33x Series, its dual-coil generator responds only to horizontal groove motion — the way mono records are cut — rejecting vertical movement so surface noise and pinch-effect artifacts simply never become signal. The result is exceptionally clean mono playback with a more substantial low end and striking midrange presence, while remaining completely safe to use on stereo pressings.

A nude conical stylus (0.65 mil) mounted on a duralumin pipe cantilever traces mono grooves precisely, and PCOCC (Pure Copper by Ohno Continuous Casting) coils deliver pure, smooth signal transmission with minimal crystal-boundary distortion. The composite cartridge body combines a die-cast zinc base, aluminum shell, and high-rigidity polymer to damp resonance throughout the structure for balanced, natural sound reproduction that lets reissues and vintage mono LPs alike speak with full authority.

With a healthy 0.42 mV output, 10-ohm coil impedance, and a standard half-inch mount with threaded inserts, the AT33xMONO/I pairs readily with MC-capable phono stages and mounts easily on most headshells and tonearms. For collectors of jazz, classical, and early rock pressings, it is a dedicated mono transducer that turns a growing mono shelf into a listening event.
