A MONO
Moving Coil Cartridge

The Ortofon Exclusives series of our highest-performing Moving Coilcartridges has now been expanded to include the brand new MC A MONO
- a TRUE MONO cartridge for play-back of MONO recordings
HIGH-END MATERIALS AND ADVANCEMENTS
IN TECHNOLOGIESThe housing of the cartridge is made in Titanium with the SelectiveLaser Melting manufacturing technique (SLM). The SLM process
welds fine particles of Titanium together, layer-by-layer, to construct asingle piece body devoid of extraneous material. This technique allows
for precise control of the density of thebody material, allowing for extremely highinternal damping. The final result provides
freedom over vibrations within the cartridge
body material.
The use of Titanium has provided a furtherimprovement to the internal damping
capabilities as well as to the overall rigidityof the structure.
Using Ortofon’s Aucurum coils of gold-plated, 6NX oxygen freecopper allows for zero-loss transmission of the diamond’s movements
via its boron cantilever. This combination combines low moving mass
with an extremely high degree of rigidity.
A specially designed armature is used to achieve extreme precisionin each coil turn in all layers. This enables the MC A MONO to achieve ahigher degree of channel separation, while simultaneously offering lower
distortion and better channel balance. The armature is made in a metalalloy which is much less magnetic than normal iron, which boosts thedynamic capability of the cartridge.
Coil wire protection has been made from our special highdamping proprietary Thermo-Plastic Elastomer (TPE) material,
which enhances the total damping properties of the cartridge.
One of the preconditions for linear reproduction with a wide frequency
range and optimal tracking performance is a diamond - the shape of
which is as close as possible to the original cutting stylus. The MC A
MONO makes use of Ortofon’s Replicant 100 diamond, known for

its thin and light profile and extraordinarily large contact surface. Special
polishing of the diamond along with the use of a Boron cantilever offer
remarkable transparency, speed, and responsiveness beyond that ofany other combination.
The magnet system is based on an extremely strong Neodymium
magnet, which makes the generator system both compact and lighter
through its minimal dimensions.
Any trace of remaining magnetic influences that would create distortionis prevented by the use of a Field Stabilizing Element (FSE). Ortofon’s
FSE, a small cylinder of conductive material strategically placed inside
the magnet system, guarantees that the force field remains stable
regardless of the movement of the armature. FSE improves the channel
separation, while at the same time minimizing dynamic distortion andintermodulation.
Adding to the list of important components is Ortofon’s Wide Range
Damping (WRD) system. In this system, a small, heavy platinum discis sandwiched between two rubber absorbers, both with different
properties. This ensures not only an exceptional tracking performance,
but also creates a perfect damping through the entire frequency
spectrum. Because of this, distortion and resonance are virtuallyeliminated entirely.

PERFORMANCE WITH A
RANGE OF COMPATIBILITY
With optimal weight and complianceto suit the vast majority of modern
tonearms, the MC A MONO is easily
compatible with a seemingly endlessarray of modern high-end turntableequipment. Low internal impedance makes the MC A MONO lesssensitive to load and therefore ensures compatibility with the Ortofon
ST-80 SE transformer, as well as with the widest range of preamps andtransformers.
