Moving Coil Cartridge

The AT33MONO is made specifically for use on mono systems. It has a horizontal coil, and so in principle only generates electricity horizontally.The AT33MONO produces sound to a very high quality because it does not easily pick up unnecessary strain components from distorted or scratched records, producing audio that you couldn’t possibly get from a stereo cartridge.The AT33MONO also has appropriate compliance in the vertical direction, so will not cause damage to stereo records. Enjoy those well-known classic mono records of yesteryear with the AT33MONO.

  • Mono cartridge compatible with stereo playback systems.
  • Elliptical stylus chip and hard duralumin cantilever.
  • 10O middle impedance specification.
  • PCOCC coil prevents crystal gain boundary formation (in transmission direction).
  • Strong body stabilized by a rigid body set-up.
  • “Hanenite” anti-vibration rubber eliminates unnecessary vibrations.
  • High-quality sound / Brass fastening screw.

*This model is not compatible with SP records.

“A True Mono Cartridge”

The AT33MONO cartridge only generates electrical signal with horizontal movement due to the horizontal configuration of the coil.

“Eliminates unnecessary vibration”

‘Hanenite’ anti-vibration high-damping rubber eliminates unnecessary vibration.

Internal wiring on AT33MONO featuring two horizontal voice coils, each voice coil terminations available independently.

Why So Many Styli Shapes?

The purpose of a stylus is to ride along the record groove capturing movement, which is then transferred into an electrical signal within the turntable cartridge. Audio-Technica produces styli in five different shapes (Conical, Elliptical, Microlinear, Shibata, and Special Line Contact) that make contact with the record groove and capture movement in different ways, creating unique sound characteristics.

Elliptical Styli

The elliptical stylus has two radii, the front radius being wider than the side radius. The front radius rides in the centre of the groove like the conical, while the smaller side radius makes more contact with the groove walls. Increased contact with the record groove walls delivers a higher level of fidelity for your sound system.
