Ortofon 2M Red

The 2M Series of cartridges is designed for precise and accurate retrieval of the information in the record groove. The name 2M was selected from several ideas. 2M means MM, which is the abbreviation for moving magnet.  The 2M series of cartridges features Ortofon’s trademark split pole pins, an invention that enables moving magnet cartridges to have a flat frequency response, as with a moving coil cartridge. Split pole pins were invented by Ortofon, and were originally presented in the 500 series and Super OM series.  We have optimized the design for ease of mounting the cartridge, and the weight and size to fit the most common turntables on the market today. The 2M Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.
