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.
The 2M technology
Both the 2M Red and 2M Blue have diamonds which are polished to the highest standards of the industry. 2M Red has a tipped elliptical diamond, and the 2M Blue has a nude elliptical diamond.
The design has been optimized for easy mounting on to a tonearm; the weight and size of all 2M models is well-suited to fit the most common turntables on today's market.
