MC Rohmann
Named after Ortofon’s former managing director, in honour of many years of service, this cartridge is milled from a solid block of aluminium. The dark blue anodised body exploits aluminium’s special damping characteristics to suppress resonance.
The slim-line Nude Orto-Line diamond ensures flawless tracking of even the most dynamic passages. MC Rohmann conveys the full range of detail and subtle nuance, even when a powerful brass section competes with the fine nuances of quieter instruments such as the flute or harpsichord.
MC Rohmann is fitted with 2.5 mm screw threads in the mounting base.
A high performance MC transformer or MC preamplifier is recommended.
Recommended load: 100 Ohms or more.
