Audio-Technica AT33xMONO/II Dual Moving Coil Mono Phono Cartridge

True Mono moving-coil cartridge designed for precise, noise-free playback of monaural vinyl records.

The Audio-Technica AT33xMONO/II is a dedicated mono cartridge crafted to deliver exceptionally pure and focused sound from monaural records. Its true dual moving-coil design responds only to horizontal groove modulation, eliminating vertical noise and providing deep, distortion-free playback.

Equipped with a nude conical stylus (0.65 mil) mounted on a duralumin pipe cantilever, the Audio-Technica AT33xMONO/II ensures excellent groove tracing and stability. The cartridge body features a die-cast zinc base, aluminum shell, and a rigid polymer top plate that suppresses resonance for natural mid-low tone reproduction.

With an output of 0.37 mV, a 20 Hz – 20,000 Hz frequency range, and a 2.5 g standard tracking force, the Audio-Technica AT33xMONO/II produces rich, authentic mono sound. Its samarium-cobalt magnet and PCOCC coils enhance efficiency and signal purity, making it ideal for high-end turntables and MC-compatible phono stages.
