The AT33xMONO/II uses a "True Mono" dual moving coil design that is engineered for pristine monaural playback. By only generating signal from the horizontal groove movement, it effectively ignores vertical noise components. The result is exceptionally clear mono sound, characterised by a more substantial low end and significantly reduced surface noise. This design is also perfectly suited for playing mono records on a stereo system.
Key Features:
- Stylus & Type: AT33x Series dual moving coil monaural cartridge with a 0.65 mil conical nude stylus.
- Acoustic Focus: Preserves the warmth and fullness of acoustic instruments, making it ideal for classic mono jazz recordings from the 1950s and '60s.
- True Mono Design: “True Mono” dual moving coil design generates the electrical signal only from horizontal movement, resulting in exceptionally clear monaural sound with a substantial low end and reduced surface noise.
- Coil Material: PCOCC (Pure Copper by Ohno Continuous Casting) coils provide pure, smooth signal transmission.
- Magnet System: Samarium cobalt magnet and pure iron yoke ensure highly efficient power generation, producing warm, richly textured playback.
- Resonance Control: The composite cartridge body (die-cast zinc, aluminium, and high-rigidity polymer) reduces resonance for balanced, natural sound reproduction.
- Vibration Damping: Highly rigid and dense die-cast zinc at the base suppresses unwanted vibrations, improving mid-to-low frequency expressiveness.
- Cantilever & Suspension: Features a high-hardness duralumin pipe cantilever and a newly developed suspension/damper design (with lower dynamic compliance) compatible with a variety of tonearms.
- Installation: Threaded mounting holes simplify headshell mounting.
- Terminal Quality: Thick gold plating on the terminal pins reduces contact resistance and enhances sound quality.
- Craftsmanship: Crafted and hand-finished by artisans in Japan.
