Audio-Technica AT-ART9XI Dual MC Moving-Coil Cartridge

Description

AT-ART9XI

Featuring a special line contact stylus on a 0.28 mm
diameter solid boron cantilever, the AT-ART9XI replaces the AT-ART9 as
Audio-Technica’s flagship magnetic core MC cartridge.

The “ART” in the model number stands for Audio-Technica
Reference Transducer, a designation that we give only to our flagship phono
cartridges. The specially designed magnetic circuit boasts an output voltage of
0.5 mV (1 kHz, 5 cm/sec), making the cartridge easy to use and capable of
reproducing even the most delicate expressions, while also ensuring dynamic
playback. The dual moving coils (fashioned from high-performance PCOCC wire)
are aligned in an inverted V shape to provide high separation and wide response
for clear sound localization and minimal distortion. Threaded cartridge
mounting holes make installation to a headshell or integrated tonearm incredibly
easy.

• Audio-Technica’s
  flagship magnetic core moving coil cartridge

• Dual
  moving coils are aligned in an inverted V shape, providing high separation
  and wide response for clear sound localization and minimal distortion

• Special
  line contact stylus ensures faithful reproduction of the music signal, and
  the 0.28 mm diameter solid boron cantilever provides excellent response
  characteristics

• Neodymium
  magnet and permendur yoke significantly increase magnetic energy

• Specially
  designed magnetic circuit provides an output voltage of 0.5 mV (1 kHz, 5
  cm/sec)

• PCOCC
  coils ensure high-fidelity transmission

• Machined
  aluminum base supports both the magnetic circuit and the vibration system,
  ensuring excellent playback stability

• Hybrid
  body of machined aluminum and high-rigidity plastic reduces undesirable
  parasitic resonance

• Threaded
  cartridge mounting holes allow easy installation to a headshell or
  integrated tonearm
