Ortofon 2M 78 Moving Magnet Cartridge

2M 78 Moving Magnet MM Cartridge, by Ortofon.

The 2M 78 features an improved engine, which provides a high level of sonic accuracy. The stylus tip is a spherical diamond that is perfect for playback of 78 rpm shellac records, which require a larger stylus profile. The cartridge body is manufactured from Hopelex, which ensures high rigidity while eliminating unwanted resonances.

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.

The 2M Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.

2M 78 Standard / 2M 78 Verso

The Ortofon 2M 78 is available in Standard model or 2M 78 Verso model. The Verso has twin screws protruding from the top of the cartridge mount, and is an alternative product for bottom mount headshells.
