The 2M Series of cartridges from Ortofon have been designed for precise and accurate retrieval of the information in the record groove. Indeed, it is Ortofon's lasting philosophy to only ever play the recorded sound, without colouration.
The pre-existing range of 2M cartridges have rapidly been established as a reference point for all good moving magnet cartridges. From the introductory Red, through to the high-end Black; 2M is now a go-to name in moving magnet technology.
2012 sees Ortofon open up new markets within the same design principle of 2M. The 2M 78 and 2M Mono offer users of older, rare vinyl a higher-quality playback medium than had previously been available.
The 2M Mono features an improved Mono engine, which provides a high level of sonic accuracy. The meticulously cut R 18µm Nude Spherical stylus is also an optimal solution for playing mono microgroove vinyl records. Re-open a whole world of Mono recordings with 2M.
Features:
- an improved engine, which provides a high level of sonic accuracy.
- R 18µm Nude Spherical diamond that is an optimal solution for playing mono microgroove LP vinyl records.
- the cartridge body is manufactured from Hopelex, an environment-friendly material which ensures high rigidity while eliminating unwanted resonances.
- 2M Mono uses a strapped output to deliver the same output signal from both sets of pole pins. This effectively eliminates the need for mono-specific equipment, making it possible to enjoy true mono reproduction on any stereo playback system.
The 2M Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.

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 and 2M Black
- 2M Mono and 2M 78
