10 - audio-technica phono cartridges guide - 2019/20
• Flagship magnetic core MC type cartridge with very high quality
magnetic circuit.
The AT-ART9 inherits the basic magnetic design from the AT50ANV, which was
developed as our 50th anniversary model. Also, it reproduces the highest-quality
sound using the vibration system from the AT-OC9/III.
•
Neodymium magnet and permendur yoke drastically increase the
magnetic energy
A neodymium magnet is employed with a maximum energy product BHmax of
50 [kJ/m
3
] whilst a permendur yoke is used with a high saturation flux density and
excellent magnetic materials.
•
Hybrid body that reduces unnecessary parasitic resonance
The housing is made of machined aluminium materials and the cover is made of
hard plastic materials. This disperses parasitic resonance and results in clear sound
quality.
• Machined aluminium base
The base that supports the magnetic circuit and vibration system is made of
machined aluminium material. This enables it to serve as a solid base to support
stable playback capability.
•
H
igh-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 oers 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 which reduce eective moving mass as seen from the stylus tip,
limiting unnecessary movement of the coil and further eliminating distortion.
•
S
pecial line contact stylus and solid boron cantilever with a 0.26mm
diameter
The stylus tip is a special line contact type with a 1.5 x 0.28 mil 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 magnetic coil.
•
Non-magnetic core MC type cartridge based on commemorative
model AT50ANV.
This product keeps the basic design of non-magnetic core MC type cartridge
AT50ANV and changes the coil winding frame from a pure titanium armature to
a newly developed liquid crystal polymer armature by an injection molding. This
product also succeeds in reducing the weight of the vibration system and provides
the extremely natural and clear sound quality with the ability to express three-
dimensional sound fields inherent to non-magnetic core types. ln addition, this
product enables an output voltage of 0.12mV, a relatively high output level for a non-
magnetic core system.
•
L
iquid crystal polymer armature
Liquid crystal polymer used for the coil winding frame not only has an extreme
mechanical strength but also a unique property which increases the mechanical
strength as the product becomes thinner.
•
Newly designed magnetic circuit that maximizes magnetic energy
The magnetic circuit of this product uses a large-sized neodymium magnet with
approximately twice the volume of conventional Audio-Technica ferrite core MC
types. The permendur magnetic circuit parts located around the magnet have also
been newly designed to maximize the strength of the intensive magnetic field in
the coil gap. This magnetic circuit increases the output voltage, and also enhances
playback capability in the medium-to-low-frequency range that is said to be a weak
point of conventional non-magnetic core MC types. This provides a very accurate
frequency response.

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