Navnet “2M” kommer fra MM (Moving Magnet). 2M-serien benytter Ortofon sitt egenutviklede konstruksjon de kaller “split-pole-pins”. En oppfinnelse som gjør det mulig for en moving magnet (MM) å tilnærme seg egenskapene til en moving coil (MC) pick-up.
2M 78, 2M Mono, 2M Blue og 2M Red har nå en forbedret spole som gir bedre lydkvalitet og et mer presist lydbilde. De mer påkostede 2M Bronze og 2M Black benytter et annet kabinett som er stivere og dermed bedre rustet mot uønsket resonans. Spolen i 2M Bronze og 2M Black har i tillegg sølvbelagt kobbertråd. 2M-serien passer de fleste platespillere på markedet samtidig som den er enkel å montere.
2M Red er en universal MM pick-up som låter åpent og dynamisk med noe innslag av varme. Om man ønsker en enkel, rimelig og god oppgradering fra f.eks. en eldre pick-up. Leveres også i verso og en PnP utgave.

Stylus lifetime: with proper care we find that up to 1000 hours is possible without degradation of performance. Please read about stylus care on our FAQ.
2M Series styli interchangeability:
The 2M Series' engines, coils and magnets configurations are not identical: Red and Blue are identical, so are the Bronze and Black and so are the true mono variants 2M Mono and 2M 78. Likewise, 2M series styli are interchangeable within the below combinations:
- 2M Red, 2M Blue and 2M Silver
- 2M Bronze, 2M Black and 2M Black LVB 250
- 2M Mono and 2M 78
Compatibility with Rega brand TT/TA:
REGA brand cartridges’ height from stylus tip to the top cartridge mounting surface is lower than standard. Therefore you would need spacers to ensure the correct set-up of the Ortofon cartridge. Please read about cartridge set-up and alignment on tonearm on our FAQ.
Adjusting the height of your Rega tonearm is easy with Acoustic Signature's Spacer Set. It allows you to adjust the height from 0.5 mm to 3.5 mm in precise steps of 0.5 mm - without removing the tone arm. Simply loosen the screws, insert the AS-spacer, then lock the screws back down, and you're tonearm is ready to play.
3.2 - 4 mm spacers should be enough for 2M cartridge.
