Ortofon 2M 78 Cartridges

Adopt a patented design with a high degree of wind needle and rod separation

Ball-shaped stylus design, more suitable for playing 78 rpm discs

Unique output design can be adapted to monophonic records to be read on stereo system

Output 4mV

Weight 7.2g

Suggested input capacitance: 150-300F

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.
- the cartridge body is manufactured from Hopelex, an environment-friendly material 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.
