Ortofon conventional VMS Magnetic cartidges
Ortofon has been designing and manufacturing magnetic cartridges for many years. At the heart of our magnetic models is Ortofon’s patented Variable Magnetic Shunt (VMS) generating system.
Compared to the conventional moving magnet systems, VMS offers reduced effective tip mass (moving mass) for better transient response, lower distortion and improved sonic depth and clarity. A conventional magnetic cartridge normally uses a solid magnet, either permanent or induced moving close to a set of coils. In Ortofon’s patented Variable Magnetic Shunt (VMS) design, the stylus cantilever is attached to a very light tubular armature which moves between the coils in the field of a miniature ring magnet.
The Ortofon VMS armature is a tiny, thin-walled tube placed at the end of the cantilever. When the stylus moved, the movements of the armature cut the flux lines of the magnet. By so doing, it functions as a magnetic shunt. VMS advantages include low moving mass, high channel separation, low distortion, minimal record wear and a superb three-dimensional sound which brings concert hall realism into your home.
