Audio-Technica AT33xMONO/II Dual Moving Coil Mono Cartridge

Highlights

• “True Mono” design rejects vertical noise for clear sound, strong bass, less surface noise
• Samarium cobalt magnet and pure iron yoke maximize efficiency and resolution
• Composite zinc/aluminum/polymer body reduces resonance
• PCOCC copper coils ensure smooth, pure signal transmission
• Conical stylus ensures accurate groove tracking

Description

The AT33xMONO/II employs a True Mono dual moving coil design that eliminates vertical noise producing clear mono sound with strong bass and reduced surface noiseideal even on stereo systems. A 0.65 mil conical nude stylus precisely tracks mono grooves supported by a piano-wire suspension for improved accuracy and mid-low range impact. Its composite zinc aluminum and polymer body minimizes resonance for balanced playback while PCOCC coils ensure pure signal transmission. A samarium cobalt magnet and pure iron yoke maximize efficiency delivering warm richly textured sound.

Features
•Dual Moving Coil Mono Cartridge with Conical Nude Stylus
•PCOCC Coils Ensure Smooth Signal Transmission
•Composite Body Reduces Resonance for Balanced Sound
•Preserves The Warmth Fullness of Acoustic Instruments

Material DifferenceThe AT33xMONO/IIs 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 cantilevers fulcrum to ensure pure transmission of horizontal mono signals.

Sound BodyEach 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 SoundThe 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 AT33xMONO/II preserves the warmth and fullness of acoustic instruments such as those captured on mono jazz recordings from the 1950s and 60s.
