Precision MicroLinear Tracking for High-Resolution Vinyl Playback
The Audio-Technica AT-OC9XML Dual Moving Coil Cartridge combines Audio-Technica's advanced OC9X moving-coil generator with a nude MicroLinear stylus engineered for exceptionally accurate groove tracing. Its narrow 2.2 × 0.12 mil contact profile follows fine groove modulation with precision, helping reduce tracing distortion and retrieve subtle musical detail, inner-groove information and high-frequency content that simpler stylus shapes may miss.
A 0.28 mm solid boron cantilever provides high rigidity with very low moving mass, while independent left- and right-channel coils use PCOCC copper in a reverse V-shaped configuration designed to reduce mechanical pressure on the stylus assembly. A rigid aluminum body, neodymium magnet and premium permendur yoke further support low resonance and efficient signal generation. With its 0.4 mV output, the AT-OC9XML is intended for high-quality analog systems equipped with a compatible moving-coil phono stage, head amplifier or step-up transformer.
Highlights & Benefits
-
Nude MicroLinear Stylus — The 2.2 × 0.12 mil line-contact profile closely follows complex groove modulation for excellent detail retrieval and reduced tracing distortion.
-
Solid Boron Cantilever — A 0.28 mm-diameter solid boron cantilever combines exceptional stiffness with low moving mass for fast transient response and precise tracking.
-
Independent Dual Moving Coils — Separate coils for the left and right channels help deliver strong stereo separation, stable imaging and accurate channel reproduction.
-
PCOCC Coil Wire — Pure Copper by Ohno Continuous Casting is used for the coil windings to support highly conductive signal transfer.
-
Rigid Aluminum Body — The cartridge housing helps minimize unwanted vibration and resonance while providing a stable mechanical foundation for the generator assembly.
Technology & Design
Nude MicroLinear Diamond — The MicroLinear stylus uses a highly refined line-contact geometry that maintains a narrow horizontal contact radius while extending vertically along the groove wall, allowing it to retrieve fine modulation with excellent accuracy.
Reverse V-Shaped Coil Configuration — Audio-Technica aligns the two moving coils in a reverse V formation to reduce pressure on the stylus assembly and help minimize distortion during groove tracking.
High-Energy Magnetic Circuit — A neodymium magnet and premium permendur yoke concentrate magnetic energy around the coil gap, supporting efficient signal generation from the lightweight moving-coil assembly.
Pre-Threaded Aluminum Housing — Integrated M2.6 threaded mounting holes allow installation with two screws and no separate nuts, simplifying attachment to compatible headshells and integral tonearms.
FAQ — Audio-Technica AT-OC9XML
What type of stylus does the AT-OC9XML use?
The AT-OC9XML uses a nude MicroLinear stylus with a 2.2 × 0.12 mil curvature radius. Its advanced line-contact shape is designed for highly accurate groove tracing and low distortion.
What tracking force should I use with the AT-OC9XML?
Audio-Technica specifies a tracking-force range of 1.8 to 2.2 grams, with 2.0 grams as the standard recommended setting.
Does the AT-OC9XML require a moving-coil phono stage?
Yes. With its 0.4 mV output, the AT-OC9XML should be connected to a compatible MC phono input, moving-coil phono preamplifier, head amplifier or appropriate step-up transformer. Audio-Technica specifies a recommended load impedance of at least 100 ohms when a head amplifier is used.
Can the stylus on the AT-OC9XML be replaced?
The stylus assembly is not field-replaceable. Audio-Technica offers a fee-based Moving Coil Exchange Program for servicing eligible moving-coil cartridges rather than using a user-replaceable stylus assembly.
