The Audio-Technica AT33xMONO/I is a specialised dual moving coil cartridge engineered for mono vinyl playback.
The latest update to the venerable AT33 Series – the first extensive overhaul in years – brings new warmth and fullness to your favorite music. Incorporating technological and material improvements, including our first use of die-cast zinc at the base of the cartridge to ward off unwanted resonance and improve expressiveness in the mid to low frequencies, the AT33x Series cartridges let you hear the finest details across the audio spectrum.
The AT33xMONO/I features a “True Mono” dual moving coil design that is unaffected by any vertical noise components picked up from the record groove, instead generating electrical signal only from horizontal movement. This results in exceptionally clear monaural sound with a more substantial low end and reduced surface noise. The dual mono coil design is also ideal for mono playback on a stereo system.
Newly Developed Suspension System
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.
Resonance Dispersion, Threaded mounting Holes
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.
Advanced DualMoving Coil Cartridge
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.
