The 2M Series features Ortofon’s trademark split pole pins,
an invention which 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 and Ortofon OM Series. The 2M 78, 2M Mono, 2M Red and 2M Blue use an improved engine, which provides an optimized sound reproduction and a high level of sonic accuracy.
The cartridge body used for the 2M Bronze and 2M Black is manufactured from Lexan DMX Piano Black, a revolutionary
material which ensures high rigidity while eliminating unwanted
resonances. The 2M Bronze and 2M Black use a special upgraded engine,
featuring split pole pins with a silver plated copper wire.
The weight and size of 2M Series have been optimized to fit the most common turntables on the market today. The cartridge body has also been streamlined to provide easy mounting and alignment. The name “2M” was chosen as it represents the abbreviation for moving magnet, MM. Moving magnet cartridges provide excellent compatibility in an assortment of playback systems and with a wide variety of phono preamps.
All of the 2M cartridges feature diamonds which are polished
to the highest standards of the industry. The 2M Red features
a tipped Elliptical diamond, while the 2M Blue features a Nude
Elliptical diamond. The 2M Bronze features a Nude Fine Line diamond stylus,which is particularly suited for demanding applications.
