Inheriting the basic magnetic design from the popular AT50ANV, the Audio-Technica Consumer AT-ART9 is the flagship magnetic core moving coil cartridge designed for Hi-Fi playback systems, providing clear and smooth sound with low distortion.

A neodymium magnet is employed for increased magnetic energy, while the hybrid aluminum/plastic body helps disperse parasitic resonance for remarkable clarity and quality of sound. The special line contract and solid boron cantilever provide accurate transfer of music signals read by the stylus tip to the magnetic coil. The AT-ART9 includes a non-magnetic screwdriver, mounting hardware, a plastic protector and a set of PCOCC lead wires.

Magnetic Core MC Type Cartridge

The AT-ART9 inherits the basic magnetic design from the AT50ANV and reproduces the highest-quality sound using the vibration system from the AT-OC9/III.

Neodymium Magnet and Permendur Yoke

A neodymium magnet is employed with a maximum energy product, BHmax of 50[kJ/m3], whilst a permendur yoke is used with a high saturation flux density and remarkable magnetic materials.

Hybrid Body Reduces Unnecessary Parasitic Resonance

The housing is made of machined aluminum materials and the cover is made of hard plastic materials. This disperses parasitic resonance and results in clear sound quality.

Machined Aluminum Base

The base that supports the magnetic circuit and vibration system is made of machined aluminum material. This enables it to serve as a solid base to support stable playback capability.

High-Separation, Wide-Response Dual Moving Coil

The basic structure is an original MC type with separate cylindrical coils to the left and right channels. Since power is generated independently in each of the left and right channels, this structure offers truly superior separation. If the signal from the opposite channel escapes, this can cause intermodulation distortion and have a decisive impact on audio quality and how the stereo sound spreads. The structure of this product ensures a clear and smooth sound. Additionally, the two coils have a reverse-V shape, reducing effective moving mass as seen from the stylus tip, limiting unnecessary movement of the coil, and further eliminating distortion.

Line Contact Stylus and Solid Boron Cantilever

The stylus tip is a special line contact type with a 40µm x 7µm curvature radius (used in the AT50ANV) and a solid boron cantilever with a 0.26 mm diameter. This allows accurate transfer of music signals read by the stylus tip to the power generating moving coils.

High Sound Quality Brass Mounting Screws

Two brass mounting screws are provided to attach the cartridge to the shell. They are optimally suited to the high sound quality of the cartridge itself.

PCOCC Coil

The PCOCC coil enables purer transmission because it does not produce grain boundaries in the direction of the transmission.
