Moving Coil Cartridge

The AT-OC9ML/II Dual Moving MicroCoil™ cartridge is a significant achievement in precision manufacturing, with tolerances held to mere thousandths of an inch. Stringent quality control assures that these tolerances, as well as performance criteria, are maintained by every AT-OC9ML/II cartridge. In addition, the AT-OC9ML/II features:

Dual-coil system for maximum channel separation.
High-flux samarium cobalt magnet for improved electrical generation.
PCOCC coil windings for low-loss “transparent” signal transmission.
Gold-plated solid boron cantilever.
Microlinear stylus

“Enables purer transmission”

The PCOCC coil enables purer transmission because it is not subject to grain boundaries in the direction of transmission.
