Product Info


The Ortofon 2M Mono cartridge is a true mono cartridge. A true mono cartridge is designed, wired and built only to retrieve signals off the record in the horizontal plane. The groove of a monaural recording is modulated only in the horizontal plane. Stereo recordings, on the other hand, are cut into the vinyl at a forty-five degree angle with a separate channel of information on each of the grove walls, thus requiring the stylus to pick up signals in both the horizontal and vertical plane. As a stereo cartridge sums the channels internally, it picks up noise from the vertical plane of the record grooves. Interestingly, in a mono record much of the surface noise is in the vertical plane, so avoiding this plane is beneficial. By not even picking up or amplifying this information you eliminate a lot of the noise from mono records that you hear when played back through a stereo cartridge.
