La Audio-Technica AT-OC9XEN is a phonograph capsule de moving coil (MC) Designed for audiophiles who want to extract every detail from their vinyl records. Its needle naked elliptical of reduced dimensions (0,3 x 0,7 mil) allows for more precise contact with the groove, translating the analog signal with extraordinary fidelity. The body of threaded aluminum It simplifies installation with screws, eliminating the need for tedious adjustments with side nuts. With a frequency response extending up to... 33kHz and a construction based on PCOCC copper For the coils, this capsule is designed for high-end equipment with a dedicated MC preamp.
Bare elliptical needle with aluminum stem
The needle naked elliptical of this capsule measures 0,3 x 0,7 milThis geometry allows for wider contact with the groove walls than a standard conical stylus. Because it's mounted directly onto the stem without intermediate adhesives, the moving mass is minimized, improving transient response and tracking ability.The stem is a tube of aluminum The square cross-section was chosen for its rigidity and lightness. This combination transmits the mechanical vibrations of the groove to the coils with minimal loss of information, especially in the high frequencies where every microsecond counts.
The practical result: acoustic instruments with more air, cymbals with natural decay, and vocals with three-dimensional presence. The difference is evident in well-mastered recordings, where the stylus extracts nuances that other conventionally mounted cartridges fail to reproduce.
Does your collection include jazz or classical vinyl records? This stylus is designed precisely for that type of repertoire, where micro-dynamic resolution makes the difference between hearing and feeling the music.
Outstanding Features de Audio-Technica AT-OC9XEN
It reduces moving mass for a more detailed and precise sound.
Quick and secure mounting on most turntable tonearms.
It offers superior channel separation for accurate stereo imaging.
It reproduces subtle highs and harmonics for a more natural sound.
Threaded body aluminum: hassle-free installation
The body of machined aluminum It incorporates two M2.6 threaded holes on the top, a mounting system that eliminates the side nuts common on other cartridges. You screw it directly onto the headshell (headshell) with the supplied screws (available in lengths of 5, 8, 10 and 12 mm), you adjust the position and you're done.This design significantly speeds up the installation and adjustment of the tonearm geometry. You don't need to hold microscopic nuts behind the headshell while trying to align the cartridge; everything is secured from above with the included non-magnetic screwdriver.
The total weight of the capsule is 7,6 gra low-to-medium value that makes it compatible with most arms of low effective mass or average. The dimensions (17,3 x 16,8 x 25,7 mm) are compact, without protrusions that could interfere with SME type headshells or similar.
It includes plastic washers to adjust the final height and ensure the cartridge is parallel to the record. If you frequently change cartridges or regularly adjust the tonearm geometry, this threaded system saves time and reduces the risk of losing screws.

Dual moving coil with copper PCOCC
Technology moving coil It differs from moving magnet (MM) cartridges in that the coils are fixed to the cantilever and move within the magnetic field, rather than moving the magnet. This drastically reduces moving mass, allowing the stylus to track the groove more accurately, especially in complex passages with many transients.Audio-Technica This capsule uses cable PCOCC copper (Pure Copper by Ohno Continuous Casting Process) for the coils. This continuous casting process eliminates grain boundaries within the conductor, reducing electrical distortion and improving signal transmission at high frequencies.
The configuration is dual coilwith an independent coil per channel. This ensures channel separation of 25 dB at 1 kHz and a balance between channels of 1,5 dBIn practical terms: the stereo image is wide, stable, and with instruments precisely located in the sound space.
The impedance of the coils is 12 Ω and the output voltage of 0,35 mV (at 1 kHz, 5 cm/sec). This means you absolutely need a phono preamp with an input MCStandard MM preamps do not have enough gain for this cartridge.
Frequency response extended to 33 kHz
The declared frequency response ranges from 20Hz to 33kHzThis extended treble is unusual for cartridges in this price range. Although the human audible range ends around 20 kHz, this additional extension ensures a flat response without attenuation in the upper part of the audible spectrum.In practice, this translates to better-reproduced transients: the initial hit of a drum, the attack of a plucked string, or the decay of a cymbal are perceived with more texture and realism. The cartridge doesn't round off peaks or smooth out details.
At the lower end, the response reaches without problems all the way down to the 20 Hzeffortlessly covering the fundamentals of bass drums, double basses, and organ pedals. Static conformity is of 20 x 10⁻⁶ cm/dyne, a value that balances tracking ability with mechanical stability.
The vertical tracking angle is 20 degrees, industry standard. The recommended support force is between 1,8 and 2,2 g, with the optimum point at 2,0 grThis adjustment should be made with a precision scale to avoid premature wear of the needle or damage to the groove.
Compatibility and system requirements
This moving coil capsule requires a phono preamplifier with dedicated MC inputIt is not compatible with standard MM phono inputs, as the output voltage of 0,35 mV It is too low for that type of circuit. The minimum recommended load impedance is 100 Ω.If your amplifier or preamplifier only has an MM input, you will need to add a step-up transformer (step-up transformeror a separate MC preamp. Many mid-to-high-end preamps already include MM/MC switching on the rear panel.
The threaded mounting system is compatible with standard headshells. SME: with hole spacing of 12,7 mm (½ inch)The most widespread format in the industry. The kit includes screws in four different lengths to accommodate headshells of varying thicknesses.
In the box you will also find a needle cleaning brush and a plastic carrying case. The brush should always be used in the direction of the needle. from back to frontNever the other way around, to avoid damaging the cantilever. Cleaning the stylus before each listening prolongs its lifespan and prevents dust buildup that affects the frequency response.
