Ortofon 2M Blue Moving Magnet Cartridge
Features a nude elliptical stylus and offers an accurate, uncolored sound
The 2M series was developed with the MøllerJensen Design from Copenhagen; the designers of the award-winning MC Jubilee and the Kontrapunkt series.
The series was designed for precise and accurate retrieval of the information in the record groove. Ortofon has optimized the design for ease of mounting the cartridge, with a weight and size to fit the most common turntables on the market today. They use diamonds that are polished to the highest standards in the industry.
To obtain a flat frequency response, Ortofon uses slit pole pins to reduce eddy currents. Slit pole pins are an Ortofon invention first used in the 500 and Super OM series. 2M Red and 2M Blue both have the same engine, which allows for an increased output of 5.5 mV.
The cartridge body of the 2M Bronze and 2M Black is manufactured from a newly-developed Noryl plastic/glass combination, a revolutionary material that ensures high rigidity while eliminating unwanted resonances. These models use a special upgraded engine, featuring split pole pins with silver-plated copper wire.
