Ortofon Hi-Fi 2M 78 Moving Magnet Cartridge
- Spherical diamond that is perfect for playback of 78 rpm shellac records, which require a larger stylus profile
- Uses a strapped output to deliver the same output signal from both sets of pole pins
2M Series
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 78 features an improved True Mono engine, which provides a high level of sonic accuracy, as well as expertly cut Spherical diamond that is perfect for playback of 78 rpm records (which require a larger stylus profile).
2M Verso
The 2M series of cartridges are now also available in a special version, suited for bottom-mount tonearms. The 2M Verso are available to special order. Head-Shell shown for illustration purposes only and not included with cartridge
Features
- Optimised sound reproduction and high level of sonic accuracy
- Spherical diamond that is perfect for playback of 78 rpm shellac records, which require a larger stylus profile

- Supplied with 2 different sets of screws (M2.5 x 5 & M2.5 x 7)

Each 2M cartridge model is also available as a 2MR variant. Here, the “R” stands for “Reduced” and relates to the lower cartridge body height. This is suited to certain types of tonearms from manufacturers such as Pro-Ject, Linn and Rega, in order to achieve the correct VTA.
