Ortofon 2M Bronze Premounted – this is how the high-resolution and dynamic 2M Bronze cartridge with naked Fine Line diamond comes pre-installed on 52mm overhang on the SH-4 Black headshell (correct Baerwald alignment for universal mounts). The SME connection allows direct mounting via bayonet catch on the S-shaped tonearm.

Before use – to avoid losses in sound quality, even pre-installed cartridges must be individually adjusted on the headshell, always according to the manufacturer's specifications of the turntable as well as the cartridge, and the tracking force must be set correctly.

True precision and new sonic dimensions with the 2M Bronze
For Ortofon, HiFi is clearly more than just a fancy label. High fidelity is the goal of all efforts here. The 2M Bronze was developed to give music completely new dimensions in terms of precision. When you listen to your records with the 2M Bronze, it's like hearing them for the very first time and you can fall in love with your favourite songs all over again. That's the Ortofon understanding of hi-fi and that's what you get with the 2M Bronze.

The Ortofon 2M Bronze features a naked Fine Line diamond, which is particularly suitable for demanding applications. The slim profile of the Fine Line stylus ensures that even the highest frequencies are captured. In addition, the larger contact area ensures less distortion and plate wear. The 2M Bronze has a special, improved motor with split pole pins and silver-plated copper wire.

The 2M Bronze Premounted is designed for easy cartridge mounting, so its weight and size fit most turntables on the market. In addition, the 2M series offers excellent compatibility with a wide range of different hi-fi chains.

Sound image – the 2M Bronze, with its very good resolution and higher transparency, offers a wide stage, many fine details and an extremely natural music reproduction. It presents itself pleasantly brilliant and balanced over the entire tonal range. Contoured bass and crisp low bass with plenty of pressure characterise the most dynamic representative of the 2M series.

Features:

Stylus with naked Fine Line diamond cut
Split pole technology
Silver-plated copper coils
Pre-installed on SH-4 Black headshell for direct attachment to bayonet connector
Enhanced sound image through reproduction of finest trebles
Compatible with most popular turntables
Easy upgrade via plug and play with Stylus 2M Black and 2M Black LVB 250 possible

Compatibility of the 2M stylus insertion
The motors, coils and magnet configurations of the 2M series are not identical on all models. The Red and Blue models are identical, as are the Bronze and Black. The 2M Silver follows its own configuration, while the true mono variants 2M Mono and 2M 78 are again identical to each other.

Technically, the following styluses of the 2M series are interchangeable in stereo application:

Stylus 2M Red, 2M Blue, 2M Silver, 2M Bronze, 2M Black and 2M Black LVB 250.

Technically, the following 2M series barrels are interchangeable in mono applications:

Stylus 2M Mono and 2M 78.

Compatibility with Rega TT/TA:
The height of Rega cartridges, from the tip of the stylus to the top of the cartridge, is lower than the standard height. Therefore, third party spacers are needed here to ensure correct mounting of the Ortofon cartridge.

The height of the Rega tonearm can be easily adjusted with additional spacers. They allow for individual height adjustment. To adjust the cartridge, simply loosen the screws, insert a suitable spacer and then tighten the screws again. After that the tonearm is ready to play.

3.2 - 4mm spacers should be sufficient for 2M cartridges.
