  • Overview

    Audio-Technica’s AT-OC9/III MicroCoil™ Cartridge features a special line contact stylus embedded into a low-profile solid boron cantilever, ensuring the music signals read by the tip of the stylus are transmitted reliably to the coils. The cartridge’s “VC mold” design ensures stability and rigidity while the dual moving coil offers excellent stereo separation and improved frequency response for long-lasting performance. The use of PCOCC wire (Pure Copper by Ohno Continuous Casting), a special copper with virtually no transverse crystal barriers to impede signal transmission, perfects the performance of the advanced dual coil design.

    AT-OC9/III MicroCoil™ Cartridge 1 5 1 1
    Four decibels high, (WAY out of balance) on RIGHT channel I am asking for an exchange. Bought from L.P. Tunes, it came with ONE SCREW holding it to the shipping mount. The RIGHT CHANNEL is 4 DB hotter than the left. It is $800 and OUT OF BALANCE. December 15, 2011

    Answer: 
    The height of the AT-OC9/III Cartridge is 17.3 mm

    We do not know the acceptable Cartridge height range specification for the Rega P3-24 Turntable

    Please consult your Turntables documentation or contact Rega for further assistance
