The AT33xMONO/II’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.
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.
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.
- AT33x Series dual moving coil monaural cartridge with 0.65 mil conical nude stylus
- Preserves the warmth and fullness of acoustic instruments, such as those captured on mono jazz recordings from the 1950s and ’60s
- “True Mono” dual moving coil design only generates electrical signal with horizontal movement for exceptionally clear monaural sound with a more substantial low end and reduced surface noise
- PCOCC (Pure Copper by Ohno Continuous Casting) coils provide pure, smooth signal transmission
-
Samarium cobalt magnet and pure iron yoke (shaped for optimal monaural sound reproduction) provide highly efficient power generation and warm, richly textured playback
- Composite cartridge body (die-cast zinc, aluminum, and high-rigidity polymer) reduces resonance throughout the body for balanced, natural sound reproduction
- Highly rigid and dense die-cast zinc material is used at the base of the cartridge to suppress unwanted vibrations and improve the expressiveness of the mid-to-low frequency range
- Threaded mounting holes make it easier to mount the cartridge to a headshell, especially one integrated into a tonearm
-
0.65 mil conical nude stylus tracks the center of the record groove for reliable performance and excellent fidelity
- High-hardness duralumin tapered pipe cantilever enhances high-frequency control
- Newly developed suspension mechanism and rubber damper design (with lower dynamic compliance than other A-T cartridges) enable the cartridge to be used with a variety of tonearms
- Thick gold plating on the terminal pins reduces contact resistance and enhances sound quality
- Crafted and hand-finished by artisans in Japan
