2MR
Thank you for choosing an Ortofon 2MR cartridge. The 2MR cartridges are high-
performance moving magnet phono cartridges with premium sound reproduction.
At Ortofon, we have been working with sound reproduction since 1918. We developed
the first phono cartridge in 1948, and since then, more than 300 different phono
cartridges have been developed and manufactured.
The 2MR has been engineered in accordance with the highest industrial standards,
matching Ortofon’s unrelenting commitment to providing the most precise and accurate
sound reproduction possible.
2MR cartridges are engineered for an optimal match with tonearms and turntables in
need of low form factor cartridges. All 2M styli fit on all 2MR cartridges.
We hope you will enjoy a premium listening experience with your new 2MR cartridge.

the mounting plate.

specifications.
5. Adjust the anti-skating according to the record player’s manual.
