The AT33xMONO/I employs a “True Mono” dual moving coil design that rejects vertical noise, delivering clear mono sound with stronger bass and reduced surface noise—ideal even on stereo systems. Its 0.65 mil conical nude stylus tracks mono grooves with precision, while a piano-wire suspension enhances tracking and mid-low range impact. A composite zinc, aluminum, and polymer body minimizes resonance for balanced playback, and PCOCC coils ensure pure transmission. Paired with a neodymium magnet and permendur yoke optimized for mono, the cartridge achieves efficient, responsive, high-resolution sound.
Features
- Dual Moving Coil Mono Cartridge with Conical Nude Stylus
- PCOCC Coils Ensure Smooth Signal Transmission
- Composite Body Reduces Resonance for Balanced Sound
Material Difference
The AT33xMONO/I’s rigid duralumin pipe cantilever, which tapers toward the conical stylus tip for improved response, is linked with a firm suspension mechanism, slightly lowering the dynamic compliance. “True Mono” PCOCC coils are positioned at the cantilever’s fulcrum to ensure pure transmission of horizontal mono signals.
Sound Body
Each AT33x Series cartridge body is constructed of three distinct materials – die-cast zinc, aluminum, and high-rigidity polymer – optimally arranged to reduce and disperse resonance across the cartridge body so that no frequency predominates during playback. Threaded holes are incorporated into the body for easy mounting.
Full, Warm Sound
The redesigned AT33x Series cartridges deliver that classic analog sound, rich in detail across the audio spectrum with lifelike expressiveness in the mid to low frequencies.
