The MC A Mono is a TRUE MONO cartridge for play-back of MONO recordings.
If
you play a MONO record with a stereo cartridge you will not achieve the
same signal in the two channels due to imperfections such as crosstalk,
noise, phase errors, tracking error, antiskating and distortion. This
difference between the channels will result in an unstable and partially
fuzzy image. A mono switch, to some extent, can improve this.
Playing MONO record with a TRUE MONO cartridge will have none of the aforementioned problems, as this cartridge only produces one signal, which afterwards is directed to both channels in the system. This will provide a much more forceful and stable image with a fuller sound.
Another significant advantage of using a TRUE MONO cartridge to play MONO records is the absence of response to vertical movement. This means that a TRUE MONO cartridge is essentially impervious to the pinching effect which comes into action when the stylus is pushed vertically upward in very narrow grooves. In addition, the response to dust, dirt and wear will be reduced substantially as the vertical component will not be heard. The final result will be a much more clean and noiseless reproduction of the MONO record. These effects simply cannot be achieved merely by the use of a mono switch.
The housing of the cartridge is made in Titanium with the Selective Laser Melting manufacturing technique (SLM).
The SLM technique was pioneered by Ortofon for manufacturing of the MC
A90 and the SPU A90 cartridges, and was refined in subsequent Exclusive
Series models.
The SLM process welds fine particles of Titanium
together, layer-by-layer, to construct a single piece body devoid of
extraneous material. This technique allows for precise control of the
density of the body material, allowing for extremely high internal
damping. The final result provides freedom over vibrations within the
cartridge body material.
The use of Titanium has provided a further improvement to the internal damping capabilities as well as to the overall rigidity of the structure.
Extremely high-end materials benefit new coil technology
Using Ortofon’s Aucurum coils of gold-plated, 6NX oxygen free copper 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 precision in each coil turn in all layers. This enables the MC A MONO to achieve a higher degree of channel separation, while simultaneously offering lower distortion and better channel balance. The armature is made in a metal alloy which is much less magnetic than normal iron, which boosts the dynamic capability of the cartridge.
Coil wire protection has been constructed from our special high damping proprietary TPE (Thermo-Plastic Elastomer) material, which enhances the total damping properties of the cartridge.
The magnet system
The magnet system is based on an extremely strong, compact neodymium magnet, which makes the generator system both compact and lighter through its minimal dimensions. Inspired by the elements of MC A95 design, the MC A MONO makes use of a specially designed armature comprised of a metal alloy which is much less magnetic than normal iron. This provides noteworthy benefit to the dynamic capabilities of the cartridge since the armature has almost no influence on the magnetic field during movement. When combined with the Aucurum coils, it delivers perfect reproduction of the cantilever movements without compromise.
Any trace of remaining magnetic influences that would create distortion is 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 and intermodulation.
