VMS 30 Mk II
VMS magnetic cartridge with Fine Line diamond, VMS 30 Mk II was the top model in Ortofon’s conventional VMS line.
In 1980-ies it was the ideal model to use with the very best turntables on the market.
It had excellent tracking ability across the entire frequency range, high channel separation, very low distortion and gave the minimum of record wear.
• High quality VMS cartridge
• Patented Ortofon VMS technology
• Nude, Fine Line stylus
• 0,45 mg effective stylus tip mass
• 20-20.000 Hz frequency response
VMS 20E Mk II
This model, which was probably one of Ortofon’s most highly acclaimed magnetic cartridges, incorporates a nude, Elliptical diamond stylus. The VMS 20E Mk II should have only be used with high quality turntables with medium to low mass tonearms. Its fine tracking ability, low tracking force and high output voltage brought out the best in any gramophone record.
• High quality VMS cartridge
• Patented Ortofon VMS technology
• Nude, Elliptical stylus
• 0,50 mg effective stylus tip mass
• 20-20.000 Hz frequency response
VMS 10E Mk II
VMS Magnetic cartridge with Elliptical diamond, an extremely robust and versatile module that used a lower compliance than our other VMS models.
Suitable for use with heavier mass tonearms.
The ideal model for manual and automatic turntables as well as record changes.
• High quality VMS cartridge
• Patented Ortofon VMS technology
• Elliptical stylus
• 0,65 mg effective stylus tip mass
• 20-20.000 Hz frequency response

FF15X Mk II and FF15XE Mk II cartridges models
The FF15X Mk II fitted with spherical diamond. The robust design and low compliance of this model make it suitable for mounting in the higher mass tonearms. The high output voltage of the FF15 X Mk II makes it a perfect match for receivers and amplifiers with a low sensitivity phono input.
The FF15XE Mk II fitted with elliptical diamond. A medium compliance cartridge which means that it can be used with a large number of turntables. The elliptical diamond provides increased high frequency tracing ability, making this model well qualified to reproduce even the most exacting music.
All above mentioned Mk II models have a redesigned body with improved shielding and repositioned terminal pins for easy connection. The pins are gold plated and have a new method of press fitting the internal connections for greater reliability and very small contact resistance.
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.
The VMS principle
Please see the diagrams illustrating the VMS principle (for simplification only one channel is shown).
The upper illustration shows the symmetrical flux fields with the armature in the central (neutral) position. These fields emanate from the magnet positioned in front of the pole pins. As the fields are in balance, no changes in flux occur around and inside the coils: therefore no voltage is generated.
The lower illustration indicates what happens when the cantilever moves the armature closer to the magnet. In this position the armature acts as a shunt, short-circuiting part of the field. As a result, the field in front of the pole pins varies, and the voltage is generated. This also occurs when the armature moves in other directions.
