Ortofon 2M Mono Verso Moving Magnet Cartridge

Ortofon 2M Mono Verso

The Ortofon 2M Mono Verso is a mono phono cartridge built for turntables whose headshells mount from underneath rather than from the top. It suits collectors who play original mono pressings on a dedicated system rather than running a stereo cartridge across mono grooves. The 2M Mono Verso separates itself from a standard stereo 2M through two things: a stylus profile cut for mono microgroove LPs, and a strapped output that keeps it working on ordinary stereo playback equipment.

Why choose the 2M Mono Verso for mono record playback?

The 2M Mono Verso is one configuration within Ortofon's 2M Mono line, and the choice to buy it over a stereo cartridge comes down to how the stylus and output are matched to mono grooves rather than stereo ones. The sections below cover what the mono-specific stylus does, how the output lets it run on a normal stereo system, how it fits a bottom-mount headshell, how it's installed, and how it compares with the other 2M Mono configurations.

What makes the 2M Mono Verso's stylus suited to mono records?

The 2M Mono Verso is fitted with a Nude Spherical diamond stylus, tipped at R 18µm and cut for mono microgroove LP grooves rather than stereo ones. This stylus profile gives focused sound reproduction and reduced surface noise when playing mono pressings, compared with tracking the same groove using a stereo-profile stylus. The nude construction is part of why: a tipped or bonded diamond has its tip mounted on a separate metal shank, which adds weight the nude diamond doesn't carry. The lighter nude assembly lets the stylus respond to the groove with less added mass, which Ortofon links to greater detail and lower distortion, and it's the construction the brand reserves for its more advanced Hi-Fi cartridges.

Can it play mono records on a standard stereo system?

The 2M Mono Verso is fitted with a strapped output, sending the same signal to both sets of pole pins rather than keeping separate left and right channels. This removes the need for mono-specific playback equipment, because the signal already arrives as true mono. Owners can run mono records straight through an existing stereo phono stage and amplifier without adding hardware.

How does it fit a tonearm and headshell?

The 2M Mono Verso is built for bottom mount headshells, the type that takes the cartridge body from underneath rather than from above, and its weight and size follow the wider 2M series design brief of fitting the tonearms most common on today's turntables. Fitting a cartridge is still a system decision, not just a mounting-style match: the total effective mass of the tonearm, including the headshell and its screws, combines with the cartridge's own compliance to set the resonance frequency of the arm and cartridge together. Ortofon's own guidance puts 7 to 12Hz as the acceptable range for this figure, with 10Hz as the target, so it's worth checking a tonearm's effective mass against the cartridge specification before buying, particularly on arms at the lighter or heavier ends of the mass scale.

How do you install and replace the 2M Mono Verso?

The 2M Mono Verso is mounted onto the tonearm using the tool supplied with the cartridge, once its top plate is set for bottom-mount use. Setting up that top plate starts with removing the stylus and its protection guard from the cartridge body, so the diamond isn't at risk during handling. A Torx 8 key then removes the black screw holding the Verso top plate in place, and the top plate lifts free once its screws are detached. The two countersunk screws in the top plate come out and are replaced with the M2.0mm screws included for the Verso configuration, and the top plate goes back onto the cartridge body flipped 180 degrees for the bottom-mount orientation. The black screw is refitted and tightened, the cartridge is mounted on the tonearm with the enclosed tool, and the stylus and its guard go back on last.

Which 2M Mono variant suits your setup — 2M, 2M Premounted, or 2M Verso?

The 2M Mono Verso is one of three mounting configurations Ortofon builds around the same 2M Mono cartridge, alongside the standard 2M and the 2M Premounted. The standard 2M suits owners who want to fit and later replace the cartridge onto a conventional headshell themselves. The 2M Premounted suits owners running an S-shaped tonearm, since it's built for direct, easy mounting and replacement without handling a separate headshell. The 2M Verso is the configuration to pick when a turntable's headshell mounts from underneath, since its top plate and screw set are specifically arranged for that bottom-mount fit rather than the top-mount fit the other two configurations assume. Buyers weighing the wider Ortofon 2M range should also note that the stereo 2M models — 2M Red, 2M Blue, 2M Bronze, 2M Black, and 2M Black LVB 250 — are built for stereo LPs; anyone whose collection is mono pressings gets the focused, lower-noise mono playback described above from the 2M Mono line instead, with the Verso, Premounted, or standard configuration chosen to match the headshell or tonearm already in use.
