Ortofon 2M Blue sound box
The same body part as the 2M Red sound box is used, but here it has a higher quality Nude Elliptical needle sanding. This is a leap forward.
2M Blue - The 2M series were developed in conjunction with Danish 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.
2M are designed for precise and accurate retrieval of the information in the record groove. Our philosophy is to play the recorded sound as accurately as possible, without coloring the sound. We have optimized the design for ease of mounting the cartridge, weight and size to fit the most common turntables on the market today.
The name 2M was selected among several ideas. We wanted a modern name which should be easy to pronounce and to remember, and therefore an alpha numerical name was chosen. 2M means MM, which is the abbreviation for moving magnet.
The 2M series of cartridges feature 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 series and Super OM series. The 2M Blue uses an improved engine, which provides an increased output of 5.5 mV.
