Ortofon 2M Red Moving Magnet Cartridge
The 2M Red and 2M Blue are designed for precise and accurate retrieval of the information in the record groove. Indeed, it is Ortofon's lasting philosophy to only ever play the recorded sound, without colouration.
To obtain a flat frequency response, as with a Moving Coil cartridge, Ortofon are using split pole pins in the 2M design, to reduce the eddy current. The split pole pins are an Ortofon invention which was originally presented in the 500 and Super OM series, to great effect.
The 2M Red and 2M Blue both use the same engine with split pole pins. With this improved engine Ortofon have been able to increase the output to an impressive 5.5 mV.
