MC Century Moving Coil Cartridge
User Guide
A century of accuracy in sound
Ortofon has always been a leading company in the field of sound reproduction.
Founded in Copenhagen in 1918, Ortofon started by creating technology which
served as the basis for adding a soundtrack to the silent movies of the early
1920s.
In 1948, the company developed the first moving coil cartridge, and since then
Ortofon has developed and manufactured more than 300 different cartridges with
our latest being the MC Century.
Today Ortofon is the world leader in cartridges. This is the result of
combining design with technology and the highest level of engineering in the
audio industry.
Acoustics, materials technology and micro mechanics are key competences in the
company´s technological prowess. Ortofon has its research and manufacturing
facilities in Denmark: the production of cartridges and components is carried
out at the factory in Nakskov. Production is based on experienced operators
with a high level of craftsmanship. This assures the high uniform quality of
Ortofon products.
Ortofon is today recognized among consumers and industry professionals as a
quality brand. Our products concentrate not only on providing the best sound,
but more importantly the faithful and correct reproduction of the recorded
sound.
Ortofon’s world-class engineering and manufacturing continually raise the bar
for accurate sound reproduction, with a vast array of products that provide
both exceptionally high performance and value for all listeners – music lovers
and highend audiophiles alike.
MC CENTURY
The MC Century represents the absolute top of Moving Coil cartridges. This
state of the art product is truly exemplary of the highest degree of
performance possible in contemporary analogue playback technology.
The MC Century represents numerous Ortofon design elements and ideals:
- The housing and the body of the cartridge are made in Titanium with SLM technique.
- High performance iron-cobalt alloy is applied for some parts of the magnet system.
- The armature damping system provides complete elimination of unwanted resonance.
- Ortofon Replicant 100 diamond, thin and light, with an extraordinarily large contact surface, tracing accuracy unparalleled by any other needle in existence.
- The crystal structure and exceptional hardness of the new Diamond cantilever ensures the best possible interface between the stylus and the armature.
Advancements in technology
An engineering feature adding to the damping capability of the MC Century
cartridge is the Selective Laser Melting process in which fine particles of
Titanium are welded together, layer-by-layer, to construct a single piece body
devoid of unnecessary material. Using this technique the density of the body
can be precisely controlled, allowing for extremely high internal damping. The
final result provides absolute freedom from resonances existing in the
cartridge body material and allows for the MC Century to be perfectly matched
with an extremely wide array of different tonearms.
The use of Titanium in the MC Century has provided a further improvement to
the overall rigidity of the structure, the cartridge weight and its dynamic
capability.
Because of the nature of SLM-based construction, each cartridge body is
cosmetically unique and will show small dimples or lines under close
examination. Magnet system
One of the most significant advantages of the MC Century is Ortofon’s high-
efficiency magnet system originally introduced in the MC Anna cartridge. The
magnet system is based on an extremely strong and compact neodymium magnet,
which makes the generator system both compact and lighter. This optimized
geometry combined with choice of materials like neodymium and iron-cobalt
offers an unprecedented consistency of the flux density within the system’s
air gap. Due to an increase of active material inside of the magnet system,
the magnetic field strength is delivered more uniformly, allowing each coil to
sense identical flux density regardless of its position. Because of this,
dynamics and impulse linearity are preserved to an overwhelming extent.
The use of this optimized magnet system allows for the use of a lightweight,
non-magnetic armature, which also provides noteworthy benefit to the dynamic
capability of the MC Century. The reason for this is that our high-tech
polymerbased armature has almost no influence on the magnetic field during
movement. Hence when combined with ultrapure oxygen-free copper coil wire, it
delivers perfect reproduction of the cantilever movements without compromise.
Because the magnet system delivers a tremendous magnetic flux density, the
need for design compromises is effectively eliminated. It is due to this
aspect that the amount of coil windings required to achieve significant output
voltages is reduced to a minimum, resulting in a further reduction in moving
mass.
The magnet system has also allowed for more spaciousness within the air gap,
allowing for coil windings to be done completely independent of each other,
without any overlap or interaction between them. The cumulative result of
these improvements simply delivers more lifelike reproduction, with nearly
boundless imaging, dimensionality, and dynamics.
Damping
One of the important design components is Ortofon’s Wide Range Damping system
(WRD), in which a small, heavy platinum disc is sandwiched between two rubber
bsorbers, both with different properties. This ensures not only an exceptional
tracking performance, but also creates a perfect damping through the entire
frequency range. Because of this, distortion and resonance are virtually
eliminated.
The MC Century uses an improved Wide-Range armature Damping system (WRD) that
provides a higher degree of control over vibrations. By extending the armature
beyond the coils, it can interface directly with the rubber dampers. This
offers more consistent movement, and thereby better stereo perspective and
transient delineation. System resonances are also damped by the use of TPE
(Thermo Plastic Elastomer) compound which comprises the bottom cover assembly.
The WRD system, which was originally introduced in the MC 20 Mk II in 1979 and
was also used in the Exclusive Series cartridges, is one significant reason
why the MC Century, while achieving the linear frequency response and the high
upper frequency limit, at the same time tracks a fantastic 80 μm at a vertical
tracking force of 2.4 grams.
Diamond Replicant 100 diamond on a new diamond cantilever Another
precondition 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.
As featured in the entire Exclusive Series, the MC Century makes use of
Ortofon’s Replicant 100 diamond, known for its thin and light profile and
extraordinarily large vertical contact surface. Since the Replicant 100 is
closest to the shape of the cutting stylus, it can trace with accuracy
unparalleled by any other stylus in existence.
Special polishing of the Nude Ortofon Replicant 100 diamond along with the use
of a new Diamond cantilever offer extremely transparency, speed and
responsiveness beyond that of any other combination. The crystal structure and
exceptional hardness of the new Diamond cantilever ensures the best possible
interface between the stylus and the armature.
Stylus protection guard
The stylus guard provided for the MC Century is designed to be easily replaced
and removed without risking contact to the fragile stylus assembly. To avoid
accidental damage to the stylus or cantilever please mount the enclosed stylus
guard onto the cartridge whenever the cartridge is not in use. The stylus
guard should also be attached during mounting or removal of the cartridge.
The stylus guard is simply removed by holding the sides between the thumb and
forefinger and pulling straight along the orientation of the cartridge.
Affixing the stylus guard is of course accomplished by the reverse movement
yet still using a straight movement.

Set-up
As with any cartridge, setup is absolutely crucial in order to ensure the
best sound reproduction capabilities. Although there are many valid paradigms
that exist with regard to cartridge setup, Ortofon does not endorse a specific
methodology and encourages users to explore the options as suggested by their
High-End Audio dealer, including professional setup.
In addition to alignment, consideration must be made to adjust azimuth, anti-
skating and VTA in order to maximize the potential performance of any high-end
cartridge.
Please find our recommendations for set-up and alignment on our HiFi FAQ:

installation Stylus Rake Angle (SRA)
With a complex stylus shape like the Replicant 100, there must be special
attention paid to positioning the diamond in the groove. The Stylus Rake Angle
(SRA – see figure) is very important to the performance of the Replicant 100
stylus, and the long contact surface (the sharp edge) of the diamond should be
almost perpendicular to the record surface when viewed from the side. The
angle between the record surface and the cantilever is close to 23 degrees
when SRA is 90 degrees.
A perfect starting point is to set the tonearm parallel to the record surface
and to use the recommended tracking force. The contact surface will be close
to perpendicular to the record surface with this setting. The SRA can now
gradually and carefully be changed be adjusting VTF and, if necessary, the
tonearm height. The target should be an SRA around 92 degrees, determined by
the listening experience. In other words, the point of the stylus should point
slightly towards the tonearm base.
Azimuth adjustment
In order to attain maximum channel separation, it may be possible to adjust
the azimuth. Should the cartridge not be perfectly perpendicular to the
record’s surface, the tonearm or headshell may require to be tilted a few
degrees.
Correct azimuth is established by observing the reflected image of the 2
parallel cartridge front lines. The cartridge’s front lines must form a
straight line with the reflected lines. A flat mirror may also be used to
facilitate this process.
Terminal connections
Please correlate the colour code for the terminals on the drawing with the
colour coding on the cartridge.
The terminals for right and left channel have the same position as normal for
Ortofon cartridges. We recommend the enclosed LW-800S leadwires to be mounted
on the cartridge and tonearm before aligning and calibrating the cartridge.
The length of the enclosed lead wires will fit a distance between cartridge
and tonearm terminals of 35 mm, which will work with most headshells.
Antiskating
Correct bias or anti-skating adjustment is important in order to achieve
optimal tracking ability and thereby minimum record wear and distortion. For
the MC Century stylus type just set normal antiskating according to
recommended tracking force.
Cartridge break-in
Although the MC Century will provide top reproduction right out of the box,
the cartridge may slightly change character during the first tens of hours of
use. This is completely normal and you may, in fact, find that this adds
further refinement to your listening experience.
