Acrolink's Mexcel 7N-D5100 Digital
Digital Cables by Acrolink
Once in a great while a product comes along that redifines state-of-the art. The Mexcel Series from Acrolink meets this criteria. Employing a radical new approach to cable design, Mexcel Series cables allow listeners to encounter prodigous amounts information previously hidden in the recordings they have been listening to for years and to have a more deeply fulfilling listening experience then they ever imagined possible.
A Miracle in High Tech Cables, the Mexcel Series Debuts
One of the most remarkable features of the Mexcel Series is its high frequency transmission capability. Acrolink has managed to increase the frequency response clear out to 18 GHz! While the frequency response of other audio cables available on the market is limited to, at best, 1 GHz, the MEXCEL series, with extremely low variance in AC resistance, has achieved revolutionary wide bandwidth response.
An Entirely New Wire Technology
To create this new series, MEXCEL insulated strands were developed using stress-free 7N copper for the inner and outer conductors. MEXCEL is a new enameled wire developed by Mitsubishi Cable Industries, Ltd., which has a rectangular shaped cross section. In the past, it has been difficult to apply insulation film evenly over the four corners of a single wire, so round conductors have been used out of necessity. Mitsubishi has developed the epoch-making MEDIS electro-deposited insulation system, which is similar to an electro-plating of the insulating resin. Unlike round conductors, rectangular conductors eliminate space between wires when wound, making it possible to manufacture high density, super high performance coils. The new ACROLINK MEXCEL series has been developed jointly by Mitsubishi Cable Industries, Ltd. and Acrolink. High density braided wires are used for signal conductors as well as shielded cables.
This type of cable falls into a category called "litz" wires in the field of audio. The cross sections are rectangular and densely braided. The sum of the cross section areas of strands made of rectangular wires is larger than that made of round wires. It has the effect of suppressing high frequency response deterioration caused by the skin effect. By braiding rectangular MEXCEL insulated strands densely, the outer conductors suppress the radiation of signals to the outside. Using rectangular strands will make the surface area larger than round strands with the same size cross section. Transmission of signals throughout the cross section is also possible thereby further suppressing the skin effect.
Coaxial type cables have a threefold covered coaxial construction (one sheath and two shields made of different material) with perfect countermeasures for external noise caused by electromagnetic waves. In the shielded two-conductor type, rectangular MEXCEL insulation strands made of high purity stress-free 7N copper are braided into both conductors and shields. In speaker cables, the semiconductor layer of insulation material suppresses the generation of static electricity caused by friction of the insulation material due to vibration and external noise from electromagnetic waves.
A special resin, used in the space and defense equipment for its extremely low dielectric constant, is used for insulation. This resin is not frequency and temperature dependent, so signals do not deteriorate regardless of frequency range and ambient temperature.
A rare variant of polyurethane resin is employed for the outer sheath. These specialized materials, coupled with precise construction and design, have yielded high quality audio cables far exceeding MIL specs. Transmitting information in unprecedented high density, the Mexcel series will enable the listener to realize the full potential of today's ever improving high-end high fidelity equipment and enter a new realm of enjoyment.
