Ortofon 2M Mono Cartridge

True Mono

“The 2M Mono is a truly exceptional transducer. The sound from this true-mono cartridge just blows away the sound you get from a mono-via-stereo cartridge setup. Because the mono cartridge only deals with the groove signal in a single plane, the resultant sound is impressively quiet compared to the modulation of surface noise and groove geometry shortcomings you often must deal with in playback of mono sources from a stereo cartridge. The end result is that you can really hear very deeply into the music; the 2M Mono sounded magnificent right out of the box, and has only gotten better as it’s broken in.” – Positive Feedback

Design Elements

The 2M Series is developed in conjunction with the Danish Industrial designer Møller Jensen Design – the same designer who designed the award winning MC Jubilee and Kontrapunkt series. Inspired by the facets of a diamond, whose contours gracefully trace the grooves on a record’s surface, the 2M’s handsome elegance establishes a great combination of form and functionality.

The name 2M was selected from among 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. Of course the 2M isn’t just another pretty face. It has been engineered to the highest standards and is congruent with Ortofon’s unrelenting commitment to providing the most precise and accurate reproduction possible without coloration.

Ortofon 2M Sonics

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 and OM Super 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.

Features

• Improved engine, provides a high level of sonic accuracy
• R 18µm Nude Spherical stylus that is an optimal solution for playing mono microgroove LP vinyl records
• 2M Mono uses a strapped output to deliver the same output signal from both sets of pole pins, which effectively eliminates the need for mono-specific equipment, making it possible to enjoy true mono reproduction on any stereo playback system

NEW!

Ortofon’s all-new 2MR series features a low-profile body for convenient mounting on Rega turntables with no shims required.  Say goodbye to expensive counterweight upgrades and aftermarket shims – the 2MR makes it easier than ever!
