Audio Technica - AT-OC9XML - Dual Moving Coil Stereo Cartridge

Premium moving coil phono cartridge with a 2.2 x 0.12 mil Microlinear stylus.

The OC9X range features a new Dual Moving Coil structure, which enables the audio information in the record grooves to be separated to the left and right channels with pinpoint accuracy. This improved channel separation results in a more precise stereo image and wider frequency response. The moving coil wires in all OC9X Series cartridges are made from PCOCC (Pure Copper by Ohno Continuous Casting), for optimum signal purity.

The AT-OC9XML utilizes a neodymium magnet with a Permendur yoke, a configuration that provides high-saturation magnetic flux density and optimizes the concentrated magnetic field of the coil gap, for improved reproduction of the delicate musical signals generated by the cartridges.

This microlinear stylus model has been upgraded with a boron cantilever carefully selected to keep unwanted vibrations to a minimum and reduce internal resonances for clearer, more detailed audio reproduction.

The AT-OC9XML’s transducer engine is mounted onto a rigid aluminium body to help reduce unwanted internal vibrations and maintain sonic clarity. The cartridge body is pre-threaded, enabling it to be easily mounted to a headshell or tonearm with just two screws (no mounting nuts for the screws are required). Each OC9X Series cartridge is supplied with mounting hardware, a stylus brush and other accessories.
