Ortofon 2M Bronze Premounted äänirasia

Premounted malli on valmiiksi tehdasasennettu Ortofon SH-4 rasiakelkkaan mahdollistaen helpon asennuksen S- vartisiin levysoittimiin.

The 2M Bronze features a nude Fine Line diamond stylus, which is particularly suited for demanding applications. The slim profile of the Fine Line stylus will track even the highest frequency information, making it a must for discerning listeners. Additionally, its larger footprint ensures reduced distortion and record wear.

The cartridge body used for the 2M Bronze and 2M Black is manufactured from a newly-developed Noryl plastic/glass combination, a revolutionary material which ensures high rigidity while eliminating unwanted resonances. The 2M Bronze and 2M Black use a special upgraded engine, featuring split pole pins with a silver-plated copper wire.

The 2M technology

2M cartridges are designed for precise and accurate retrieval of the information in the record groove. Ortofon's philosophy is to play the record sound as accurately as possible, without colouring the sound in any way. Both the 2M Bronze and 2M Black have diamonds which are cut and polished to the highest standards of the industry.

The 2M design has also been optimized for easy mounting on to a tonearm; the weight and size of all 2M models is well-suited to fit the most common turntables on today's market.

The 2M Bronze and 2M Black also have interchangeable stylus units, and replacement styli are readily available in the UK.

About the unique 2M design

2M was developed by Ortofon in conjunction with "Møller Jensen Design" from Copenhagen, Denmark - the same designer who collaborated on the award-winning MC Jubilee cartridge, and the coveted Kontrapunkt series.

The inspiration for designing the 2M was related to the facets of the diamond - elegantly concentrating its contours against the grooves on the record surface.

The name 2M was selected among several ideas. Ortofon wanted a modern name which would be easy to pronounce around the world, and to remember. Therefore an alpha-numerical name was chosen...
2M means MM, which is simply the common abbreviation for Moving Magnet.

The 2M range has been structured in the same way as the popular Rondo and Cadenza Moving Coil series, with ascending quality as you move from Red - Blue - Bronze - Black. The spectacular 2m Black has become the flagship of 2M, and all Ortofon moving magnet cartridges.

2M was also the last product designed by Ortofon's former chief engineer, Per Windfield. He developed the 2M series over the final 2 years of his 30 year tenure with Ortofon.

Stylus lifetime: with proper care we find that up to 1000 hours is possible without degradation of performance.

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 and 2M Black

- 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.

Features:

The 2M Bronze features a nude Fine Line diamond stylus, which is particularly suited for demanding applications. The slim profile of the Fine Line stylus will track even the highest frequency information, making it a must for discerning listeners. Additionally, its larger footprint ensures reduced distortion and record wear.

The cartridge body used for the 2M Bronze is manufactured from a newly-developed Lexan DMX Piano Black, a revolutionary material which ensures high rigidity while eliminating unwanted resonances.

We have optimized the design for ease of mounting the cartridge, and the weight and size to fit the most common turntables on the market today. The 2M Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.

The 2M Bronze uses a special upgraded engine, featuring split pole pins with a silver plated copper wire.
