The AT33xMONO/I features a "True Mono" dual moving coil design engineered specifically for superior monaural playback.

This design is uniquely capable of generating the electrical signal only from horizontal movement within the record groove. Crucially, the system remains unaffected by any vertical noise components, which typically contribute to signal interference.

This specialised focus results in exceptionally clear monaural sound, characterised by a more substantial low end and significantly reduced surface noise. Furthermore, this dual mono coil design is perfectly ideal for achieving authentic mono playback on a standard stereo system.

This monaural cartridge, featuring a 0.65 mil conical nude stylus, is engineered for balanced, high-resolution sound reproduction, bringing out all the details in the music.

Key Features:

  • "True Mono" Design: The dual moving coil system only generates a signal from horizontal movement, effectively eliminating vertical noise components. This results in exceptionally clear mono sound, reduced surface noise, and a substantial low end.
  • Pure Signal Path: Uses PCOCC coils and an optimised neodymium magnet/permendur yoke for high-resolution, responsive playback.
  • Resonance Control: The composite body (die-cast zinc, aluminum, high-rigidity polymer) and dense die-cast zinc base actively reduce and suppress unwanted vibrations across all frequencies, particularly in the mid-to-low range.
  • Durable Build: Features a high-hardness duralumin pipe cantilever and a newly developed suspension system (with lower dynamic compliance) compatible with various tonearms.
  • Convenience: Includes threaded mounting holes and thick gold plating on the terminal pins to reduce contact resistance.
  • Quality: Hand-finished by artisans in Japan.

Monophonic Suspension and Coil System

The AT33xMONO/I features a rigid duralumin pipe cantilever designed for superior response. The cantilever tapers toward the conical stylus tip, enhancing signal retrieval. This assembly is connected to a firm suspension mechanism, which slightly lowers the dynamic compliance for stable tracking. For pure signal integrity, "True Mono" PCOCC coils are positioned at the cantilever's fulcrum, ensuring the transmission of only the horizontal mono signal.

Resonance Control and Mounting

The cartridge body utilises Resonance Dispersion technology for optimal acoustic performance. Each AT33x Series body is constructed from three distinct materials—die-cast zinc, aluminum, and high-rigidity polymer—strategically arranged to reduce and disperse resonance. This multi-material approach ensures that no single frequency predominates during playback. For ease of installation, the body incorporates threaded mounting holes.

We endeavour to despatch same day for orders placed up to 1pm on available stock items (items with stock message "Usually dispatched within 24 hours").
