Dual voice coil capsule with Shibata diamond and advanced boron tapered cantilever, and reduced weight. Neodymium magnet with increased magnetic energy. PCOCC coil. VC mold that limits unnecessary vibrations.

The AT33Sa is Audio-Technica's first MC cartridge to feature a Shibata stylus. In addition to its excellent high frequency performance as a linear contact stylus, the Shibata stylus produces powerful and rich bass and mids. The Shibata stylus is mounted on a double dampened boron cantilever to greatly improve sound quality.

Advanced

Low Weight Boron Tapered Cantilever The AT33Sa uses a boron tapered cantilever. Narrowing the cantilever and checking the number of turns of the thread reduces the weight, giving the capsule better performance at high frequencies and a wider range of reproduction.

Neodymium magnet with considerable increase in magnetic energy, and permendur yoke

This model uses a neodymium magnet with a maximum energy product BHmax of 50 [kJ / m3] and a permendur yoke with high saturation flux density and surprising properties. magnetic, which further enhance the concentrated magnetic field in the coil groove.

Neodymium magnet for considerable increase in magnetic energy

The neodymium magnet provides maximum energy (BHmax of 50 [kJ / m3]), while the pure iron yoke provides excellent magnetic properties. Together, they further strengthen the concentrated magnetic field in the coil groove area.

PCOCC Coil

The PCOCC coil allows for a purer transmission as it is not subject to granular contours in the direction of transmission. * PCOCC = Pure Copper by Ohno Continuous Casting process (high purity, oxygen-free monocrystalline copper)

Dual voice coil with wide gap and response.

The basic structure is the MC type, with independent cylindrical coils for the left and right channels. Since the power is generated independently for the left and right channels, this structure offers a very considerable separation. If signal escapes from the opposite channel, intermodulation distortion can occur, which has a decisive impact on audio quality and the way sound is delivered. The structure of this product ensures a clear and uniform sound. In addition, the two coils have an inverted V shape that reduces the effective mass in motion, as seen from the tip of the needle, limiting unnecessary coil movements, and thus further eliminating distortion.

VC mold that limits unnecessary vibration.

The VC mold that fixes the coils is constructed of hard synthetic resin that contains potassium titanate for added strength and rigidity. This results in a lighter product that reduces unnecessary vibrations.

A tough body designed to be rigid.

The product housing is constructed of precision aluminum hard cast alloy. Hard synthetic resin layers on the top and bottom eliminate parasitic resonances. This minimizes unnecessary noise, while reinforcing stiffness and improving the signal-to-noise ratio.
