Ortofon 2MR Mono

Ortofon 2MR Mono Cartridge

Experience the pinnacle of mono playback with the Ortofon 2MR Mono cartridge, designed to deliver unparalleled performance for your mono microgroove vinyl records. Sharing the same specifications as the renowned Ortofon 2M MONO, this cartridge stands out with its reduced height, suitable for tonearms with low VTA and no arm height adjustment.

Features

The Ortofon 2MR Mono cartridge is equipped with a stylus featuring an R 18µm nude spherical diamond tip, optimized for playing a wide range of mono recordings. The cartridge body is crafted from Hopelex, a material that ensures high rigidity while eliminating unwanted resonances.

Design

Boasting a high-performance motor system housing four coils and Ortofon’s exclusive innovation - the split pole pins, the 2MR Mono stands out. The split pole pins allow the cartridge to use a common output connected to both sets of pole pins, eliminating the need for mono-specific equipment. This design guarantees authentic mono reproduction on any stereo playback system.

Integration

The 2MR Mono cartridge is housed in a meticulously designed cartridge shell for turntables and tonearms, such as Rega, meeting their requirements for low-height cartridges. Its slim shell seamlessly integrates without requiring modifications or shims under the tonearm. Enjoy quick and hassle-free mounting with just two screws, allowing you to focus on the music rather than complex installation processes.
