7N. Seven nines. Purity 99.99999% or more. … (Note: Except for ○○)… All inclusions = Gold and silver are counted as impurities, and the total amount is 0.00001% or less, which is Acrolink’s 7NCu. And stress-free processing only for Acrolink that maintains high performance at the site of use. However, what happens if there are defects such as impurities in the materials such as insulators, sheaths, shields, and terminals that are integrated into 7NCu? Extremely high performance of audio files in various spaces. This is the attitude of Acrolink. That is, it is the purity of each material other than 7NCu, and if it is a mixed material, it is quality control for homogenization. Advances to Gigahertz Transmission Cables are also a major uncertainty in a mixed digital and analog environment, and their responsibilities are significant. The cable body has “Acrolink balance = 0.” 19 pieces of 26φ strands are twisted at high density while being coated with squalane oil, and natural silk threads are placed along them to remove static electricity. A PTFE Teflon tape with a low dielectric constant is wrapped around this core wire, coated with cross-linked polyethylene, and has a two-layer structure with two types of insulators to eliminate unnecessary vibration. The shield has a double shield layer made of copper foil tape and silver-plated annealed copper braid, and noise countermeasures are perfect. The outermost circumference is a transparent UV-resistant polyurethane finish that does not use pigments. And the “terminals” that affect the total quality. Acrolink has developed original terminals since its establishment. 7N-D5050 Leggenda inherits the highly complete 7N-D5050Ⅲ / 7N-D5070Ⅲ terminals. At the RCA terminal, the center pin has a hollow structure made by carving out high-quality, high-density tellurium copper without iron components to increase the surface area and reduce resistance. Thick rhodium plating also realizes long-term reliability. Resonance is greatly reduced by combining a hybrid cover made of beryllium copper, carbon fiber, and aluminum on the cold side body. At the BNC terminal, the contact pin is machined from high-quality solid phosphor bronze with no iron component and finished with gold plating. The cold side body is machined from solid brass. The insulator is PTFE Teflon. The cover is a combination of brass, carbon fiber, and aluminum to suppress vibration, suppress microphonic noise, and achieve perfect noise countermeasures and high fidelity transmission. The 7N-D5050 Leggenda is a cable with extremely high performance as both a digital cable and an analog cable by setting the impedance to 75Ω and the ultra-wide range with an eye on gigahertz transmission. High-density and clear sound fine particle reproduction over the entire band, texture with excellent pitch feeling, low range that powerfully conveys volume, direct sound, indirect sound vividly drawn on the time axis, and precise transmission ability Improvement. It is the latest work that can be said to be the “prototype” of coaxial audio cable by condensing many years of know-how and brushing up to advanced materials. The insulator is PTFE Teflon.

7N DUCC Cu : Dia Ultra Crystallized Copper is a high-purity copper conductor for audio cables developed by Mitsubishi Cable Industries Ltd., which grows crystal grains to several tens of times larger than general pure copper and aligns the direction of the crystal lattice. It is a material. The larger the crystal grain, the smaller the grain boundary (boundary surface between crystals), which has a great advantage in sound quality, but metal crystals have directionality and it was necessary to align them as well. The direction can be observed by the analysis phenomenon by X-ray irradiation, but by optimizing the manufacturing process such as bus line, wire drawing process, annealing (annealing), “optimal direction for audio signal transmission” is provided. An extremely good wire rod was completed.
Original stress-free 7NCu : Acrolink ‘s stress-free products use a unique special annealing treatment and high-purity copper properties to restore the tissue to a healthy state by self-annealing unless the external stress is too high. But it’s the only cable. At the time of heat treatment after wire drawing, the atomic arrangement transition is on the order of 1/1 billion compared to ordinary 4N copper, and the number of crystal grains is 1/80 to 1/100. Furthermore, the flow of electric current promotes the aging = self-annealing environment, reduces residual strain, restores the structure soundly, and improves the sound quality.
