Since its introduction more than 30 years ago, Audio-Technica’s pioneering moving coil OC9 cartridge series has been prized by demanding vinyl listeners and professional critics alike for its musical transparency, expression of sound and precise construction. Microlinear complex diamond profile enabling higher frequency response, detail like never before experienced and limiting inner groove distortion. Microlinear diamond profile provides low record and stylus wear. Features nude Microlinear stylus and boron cantilever which provides lower distortion and high transient response A neodymium magnet and permendur yoke provides dramatically increased magnetic energy Threaded inserts in the cartridge body enable the cartridge to be mounted on to the headshell or integral tonearm with just two screws – no nuts required Aluminium body minimizes unwanted vibration for reduced resonance and a superior audio reproduction Pure Copper by Ohno Continuous Casting process (PCOCC) is used for the coils to achieve pure signal transfer Features Features nude Microlinear stylus and boron cantilever Neodymium magnet and permendur yoke for increased magnetic energy Features threaded inserts in the cartridge body Aluminium body minimizes unwanted vibration for reduced resonance PCOCC is used for the coils to achieve pure signal transmission Specs Model AT-OC9XML Mounting 1/2” centers / Threaded Frequency Response 20 to 47,000 Hz Body Material Aluminium Channel Separation 27 dB (1 kHz) Output Channel Balance 1.0 dB (1 kHz) Output Voltage 0.4 mV (at 1 kHz, 5 cm/sec) Vertical Tracking Angle 20 degrees Vertical Tracking Force Range 1.8 to 2.2 g (standard 2.0 g) Stylus Shape Microlinear Stylus Size 2.2 x 0.12 mil Stylus Construction Nude square shank Cantilever 0.28 mm Ø nude boron Coil Impedance 12 Ohms (1 kHz) Coil Inductance 25 μH (1 kHz) DC Resistance 12 Ohms Static Compliance 20 x 10 – 6 cm / dyne Dynamic Compliance 16 x 10 – 6 cm / dyne (100 Hz) Terminal Pins Brass Wire Used for Coil PCOCC (Copper by Ohno Continuous Casting process.)
