Ortofon 2M 78, 2M 78 Verso and 2M 78 PnP

The 2M 78 Series – the true MONO from Ortofon!

The 2M Series of cartridges is designed for precise and accurate retrieval of the information in the record groove. Our philosophy is to play the record sound as accurate as possible, without coloring the sound.
The name 2M was selected from several ideas. We 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 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 Super OM series.
We have 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.
2M 78 Verso Mono

The 2M 78 Verso model is an alternative cartridge for bottom mount tonearms

The 2M 78 features:
An improved engine, which provides a high level of sonic accuracy
Spherical diamond that is perfect for playback of 78 rpm shellac records, which require a larger stylus profile
2M 78 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
