Featuring a special line contact on a boron cantilever, the AT-ART9XI replaces the AT-ART9 as Audio-Technica's flagship magnetic core MC capsule. The "ART" in the model number stands for Audio-Technica Reference Transducer, a component used only in our premium quality cartridges. The specially designed magnetic circuit features an output voltage of 0.5 mV (1 kHz, 5 cm / sec), making the capsule easy to use and capable of reproducing even the most delicate expressions, while ensuring dynamic playback. The capsule mounting threaded holes greatly facilitate installation on a helmet or integrated turntable arm.

Characteristics:

High-clearance, wide-response dual voice coil.

The system's dual voice coils are aligned in an inverted V shape, providing high clearance and wide response for clear sound localization and minimal distortion.

Special line contact needle and a 0.28mm diameter solid boron cantilever

The SLC stylus ensures a faithful reading of the music signal, while the boron cantilever offers excellent response characteristics.

Neodymium magnet and permendur yoke to significantly increase magnetic energy.

The specially designed magnetic circuit optimizes the energy in the magnetic space where the generator coils meet. Enjoy dynamic playback with an output voltage of just 0.5mV.

PCOCC coils for high fidelity transmission.

Using PCOCC (Pure Copper Ohno Continuous Cast) wire for the coils achieves pure signal transfer.

Machined aluminum base for stable playing.

The machined aluminum base supports both the magnetic circuit and the vibration system, ensuring excellent playback stability.

The hybrid body reduces undesirable parasitic resonance.

The machined aluminum housing combined with high-rigidity plastic helps reduce undesirable parasitic resonance to improve sound quality.

Threaded capsule mounting holes for easy installation into housings or integrated cranks.

The capsule body includes threaded screw holes that allow it to be installed in head caps or built-in toneries with just two screws (no nuts required).
