Ortofon 2M Blue Cartridge Mounted on SH-4 Headshell - Discontinued - Replaced by Ortofon 2M Blue Mounted on SH-4 Black Headshell

• An improved engine providing an increased output of 5.5 mV and an optimized sound reproduction and a high level of sonic accuracy
• A nude Elliptical diamond and split pole pins with a copper wire
• Adds more dynamics and resolution, sounds more open and reproduces more detail

Ortofon has 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.

The 2M Blue adds more dynamics and resolution, sounds more open and reproduces more details compared to the 2M Red model.

The 2M Series is developed in conjunction with the Danish Industrial designer Møller Jensen Design - the same designer who designed the award winning MC Jubilee and Kontrapunkt series. Inspired by the facets of a diamond, whose contours gracefully trace the grooves on a record’s surface, the 2M’s handsome elegance establishes a great combination of form and functionality.

The name 2M was selected from among several ideas. Ortofon wanted a modern name that would be easy to pronounce and remember, and therefore an alphanumerical name was chosen. 2M means MM, which is the abbreviation for moving magnet.

The 2M has been engineered to the highest standards and is congruent with Ortofon’s unrelenting commitment to providing the most precise and accurate reproduction possible without coloration.

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 OM Super series.

2M Series styli interchangeability:
The 2M Series' engines, coils and magnets configurations are not identical: Red and Blue are identical, so are the Bronze and Black and so are the true mono variants 2M Mono and 2M 78. Likewise, 2M series styli are interchangeable within the below combinations: 
- 2M Red, 2M Blue and 2M Silver
- 2M Bronze, 2M Black and 2M Black LVB 250
- 2M Mono and 2M 78
