La Audio-Technica AT-OC9XML is a phonograph capsule with a moving coil designed to extract the maximum detail from your vinyl records. Equipped with a stylus Microlinear diamond and a cantilever of boron, reproduces frequencies from the 20 Hz to 47.000 Hz with minimal distortion. Its aluminum body and threaded mounting system facilitate installation on any standard headshell tonearm. 1/2 inchIt is aimed at discerning listeners who seek fidelity and precision in analog reproduction, and requires a phono preamplifier compatible with moving coil cartridges.
Microlinear Needle: elimination of distortion in internal tracks
The stylus's cut replicates the geometric shape of the original cutting stylus that engraved the record. This allows the diamond to rest in the grooves with the same contact surface as the recording stylus, drastically reducing wear. internal track distortion (Inner Groove Distortion), the most common problem in the last few minutes of each side of the vinyl record.The Microlinear profile measures 2,2 x 0,12 milThis means the contact area is elongated and narrow. This geometry allows for precise tracking of the fastest and most complex modulations, especially at high frequencies, without losing information or generating spurious harmonics.
In addition, distributing the weight over a larger surface reduces wear on the groove and the needle itself. Audio-Technica specifies a service life of up to 1.000h reproduction, far superior to conventional elliptical needles.
In practice: the final tracks of an album sound as crisp as the first tracks, without that characteristic muddiness or exaggerated sibilance that appears with less advanced needles.
Outstanding Features de Audio-Technica AT-OC9XML
It reduces distortion, especially in the inner tracks of the vinyl, for a cleaner sound.
It offers superior transient response, capturing subtle details in the music.
It minimizes unwanted vibrations, resulting in a purer reproduction.
It allows for direct and secure installation on the headshell, without the need for nuts.
It reproduces ultra-high and low frequencies for a complete listening experience.
It works optimally with standard MC preamps, facilitating compatibility.
cantilever boron 0,28 mm in diameter
The cantilever is the rod that transmits the needle's movement to the generator coils. In the AT-OC9XML, it is manufactured in bare boron, an extremely lightweight and rigid material that offers a sound transmission speed superior to that of aluminum.With a diameter of only 0,28 mmThis tube has minimal mass, resulting in exceptional transient response. Percussive attacks, drum hits, and pizzicatos are reproduced with speed and definition, without any trails or unwanted resonances.
The combination of boron and a Microlinear stylus allows the cartridge to follow the most demanding groove modulations without loss of information. The dynamic conformity of 16 x 10⁻⁶ cm/dyne at 100 Hz It ensures that the assembly oscillates with controlled freedom, adapting to the irregularities of the vinyl without sacrificing precision.
The result: a stable stereo image, with instruments clearly separated in space and a sense of 'speed' that makes the music sound alive and present.

PCOCC Coils and neodymium magnetic system
Moving coil technology places the coils at the end of the cantilever, instead of fixing a magnet as in moving magnet (MM) cartridges. As they move within the magnetic field, the coils generate an electrical signal proportional to the groove's movement.Audio-Technica uses PCOCC copper (Pure Copper by Ohno Continuous Casting) in the winding, a material with a near-perfect crystalline structure that minimizes electrical discontinuities. The result is a cleaner signal, with less harmonic distortion and better transient response.
The magnet of neodymium It generates an intense magnetic field in a very small space, allowing for increased sensitivity without increasing moving mass. The coil impedance is 12 Ω at 1 kHz, with an inductance of 25 μH, values that facilitate compatibility with high-quality MC preamplifiers.
The output voltage is 0,4 mV at 1 kHz (measured at 5 cm/sec), typical of MC cartridges. You need a specific preamplifier with adequate gain and a minimum load impedance of 100 Ω.
Her first book of poems, Cuerpo, made of aluminum and direct threaded mounting
The capsule body is manufactured entirely in aluminumThis material combines lightness with high rigidity. This structure minimizes internal vibrations and resonances that could color the sound, especially in the mid and high frequencies.Does your tonearm use screws to attach the cartridge? The AT-OC9XML features integrated threaded holes, allowing for direct mounting without nuts. This simplifies installation, reduces the number of metal parts in contact, and improves mechanical transfer between the cartridge and headshell.
The box includes M2.6 screws 5, 8, 10 and 12 mmplastic washers, a non-magnetic screwdriver, and a cleaning brush. The total weight of the capsule is 7,6 gr, compatible with most medium effective mass arms.
The vertical tracking angle is 20 degrees, industry standard. The recommended support force is 2,0 grwith an operating range of 1,8 to 2,2 g. These values facilitate adjustment and fine-tuning on any quality plate.
Answer in extended frequency up to 47 kHz
The stated frequency response ranges from 20Hz to 47.000HzThis figure far exceeds the human audible limit. Although you may not consciously perceive frequencies above 20 kHz, their presence influences the phase and harmonic interaction of the entire spectrum.At the low end, the capsule accurately reproduces from the 20 Hzcapturing the sound of double basses, bass drums, and pipe organs. The static conformity of 20 x 10⁻⁶ cm/dyne It allows the cantilever to follow low-frequency modulations without excessive rigidity.
The channel separation is 27 dB at 1 kHzA solid value that ensures a defined stereo image. Instruments located at the extremes of the sound field maintain their position without 'bleeding' into the opposite channel.
Overall, the AT-OC9XML delivers a coherent, balanced spectrum with minimal coloration. It doesn't exaggerate bass or boost treble: it reproduces what's recorded in the groove, faithfully and without embellishment.
