Ortofon 2M Red Cartridge
2M Series cartridges are designed for precise and accurate retrieval of the information in the record groove. Ortofon's philosophy is to play the record sound as accurate as possible, without colouring the sound. They have optimised the design for ease of mounting the cartridge, weight and size to fit the most common turntables at the market today.
2M has been engineered to the highest standards and is congruent with the unrelenting commitment of Ortofon to provide the most precise and accurate reproduction possible without coloration.
Ortofon from Denmark is the world's largest producer of magnetic cartridges for phonograph turntables and is the leading specialist and developer of professional audio products including cartridges for use in radio stations and other professional applications.
In 1948 Ortofon developed its first moving coil cartridge, since then more than 300 different cartridges have been developed and manufactured. Acoustics, materials, technology and micro mechanics are key competences in Ortofon's technological prowess. Research and development is done with the company's own engineers supported by a strong network of acoustic know-how and industrial design in Denmark.
In 1957 Ortofon introduced a moving coil stereo cutter head and followed this in 1958 with the introduction of the "Stereo Pick-Up" or SPU, designed by Robert Gudmandsen. Initially Ortofon supplied these new cartridges in the Type A headshell, designed to be used in their own RMA pickup arm, to broadcast turntable manufacturers, including EMT.The SPU was used by early broadcasting companies among whom the Ortofon brand name was already well known from the first moving coil system - the Ortofon mono system in the small black A-housing. The so-called “Ortofon sound“ became synonymous with the sound from the SPU, at an early stage.
The sound of the SPU cartridge is characterized by a rich bass and a transparent treble range plus those extra qualities which are so hard to define, but so easy to appreciate when they are realized.The characteristics and heritage of these early SPU designs have been embodied in Ortofon's current cartridge range whether they be Moving Coil or Moving Magnet designs.
The 2M Red is an excellent choice. You'll hear quieter backgrounds, a cleaner midrange, and more detail, treble, and bass. 2M series of cartridges feature 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 Super OM series.
The 2M Red uses an improved engine, which provides an increased output of 5.5mV.
2M red features a tipped elliptical diamond which goes deeper into the record groove to extract those musical detail nuances that make the performance special.Due to the increased surface contact of the record groove record wear is also minimised.
