The new Ortofon 2M 78 Series - the TRUE MONO from Ortofon!


designed for playback of 78 rpm shellac records, which require a larger stylus profile ● Strapped output to deliver the same output signal from both sets of pole pins thus enabling True mono reproduction on a stereo playback system.

Ortofon's 2M 78 cartridge has made a deep impression on me; it is an incredibly cost effective addition to my system which unlocks a massive quantity of mono music for my enjoyment. - Enjoy the Music

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 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, weight and size to fit the most common turntables at the market today. 2M Series provides excellent compatibility in an assortment of playback systems and with a wide variety of phono preamps.

Don't use these with Modern Audiophile Mono records as their stylus tip will be too large and stereo records will be badly damaged due to the lack of vertical compliance 2M 78 features R 65 µm Spherical diamond that is perfect for playback of 78 RPM Shellac Records ONLY which require a larger stylus profile.

Ortofon: 'Accuracy in Sound'
Ortofon is the world’s oldest and most experienced manufacturer of hi-fi pick-up cartridges. From humble beginnings in 1918, Ortofon is now a prolific winner of various international awards, and consistently well reviewed by the international press with every new product. Their core principles of responsibly sourced high-end materials, meticulous design and production processes, pristine working conditions and superlative attention to detail are evident in every single product they make.
From the introductory moving magnet OM and 2M models, through the Vivo, Rondo and Cadenza Moving Coil series, all the way up to the high-end MC Windfeld, Xpression and brand new MC Anna cartridges, Ortofon are devoted to offering true ‘accuracy in sound’. They also commit to supporting long-time customers by continuing to run replacement styli many years after an original cartridge has been discontinued, and for Moving Coil customers they also run an attractive Exchange Program .
Nothing demonstrates Ortofon's long-standing resilience more than its commitment to the refinement of analogue sound quality and its continued development of new cartridge models. Since 1948 Ortofon have introduced about 100 different moving coil models, with their latest being the Quintet Series.
Ortofon believe the cartridges in this new series are more than worthy successors to the long line of models that have made Ortofon the global leader in the manufacturing and supplying of phono cartridges.
