AT33xMLD
AT33xMLD
The latest update to the 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.
Featuring a microlinear nude stylus set to a duralumin tapered pipe cantilever, the AT33xMLD delivers warm, detailed sound, making it an excellent choice for rock and jazz records. Our newly developed suspension mechanism uses piano wire for even better tracking accuracy, lowering the dynamic compliance slightly for more substantial audio, particularly in the mid-low range.
The cartridge’s composite body, made of die-cast zinc, aluminum, and high-rigidity polymer, reduces and disperses resonance across the entire body, resulting in balanced, natural sound reproduction that doesn’t favor particular frequencies. The AT33x dual moving coil cartridge design features independent left- and right-channel PCOCC (Pure Copper by Ohno Continuous Casting) coils for outstanding channel separation and pure, smooth signal transmission. A neodymium magnet and permendur yoke create a strong magnetic field that maximizes power generation efficiency, resulting in responsive, high-resolution analog playback.
Like all AT33x Series cartridges, the body of the AT33xMLD includes threaded holes for easy mounting (just two screws required). These threaded holes are especially useful when mounting the cartridge to an integrated tonearm.
Material Difference
The AT33xMLD’s rigid duralumin pipe cantilever, which tapers toward the microlinear stylus tip for improved response, is linked with a firm suspension mechanism, slightly lowering the dynamic compliance. Two independent PCOCC coils are positioned at the cantilever’s fulcrum to ensure pure signal transmission for each channel.
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.
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. The AT33xMLD is an excellent choice for playing rock and jazz records, particularly those recorded in the 1950s, ’60s and ’70s.
Features
