Ortofon 2M 78 sound box

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 among several ideas. We wanted a modern name that would be easy to pronounce and to remember, and therefore an alpha numerical name was chosen. 2M means MM, which is the abbreviation for moving magnet.

The 2M series of cartridges feature Orthophone's trademark split pole pins, an invention that enables moving magnetic 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, weight and size to fit the most common turntables at the market today. The 2M Series provides excellent Compatibility in an assortment of playback systems and with a wide variety of phono preamps.

The 2M 78 Series features:

• An improved engine that provides a high level of Sonic accuracy
• Spherical diamond that is perfect for playback of 78 rpm shellac records, which requires a larger stylus profile
• The 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
