A megahertz is ten times larger than 100 kilohertz, and a gigahertz is a further 1,000 times larger, so 1 GHz is 1 billion Hz. At the gigahertz level, extremely accurate waveform transmission without corruption to the signal waveform is possible in digital transmission. Even in analog transmission, flat frequency response can be achieved in the entire audible range.
As the main conductor, MEXCEL series cables incorporate D.U.C.C.* 7N Cu developed by Mitsubishi Cable Industries. With 99.99999% purity, controlled in a base material production process equivalent to that used for semiconductors where high-level quality assurance is demanded, total metallic impurities are kept to less than 0.1 ppm. With respect to crystalline structure deterioration caused by bending when in use, excellent transmission characteristics are maintained using special “Stressfree” processing developed by ACROLINK for self-annealing at room temperature to preserve the optimal crystalline condition.
* D.U.C.C.: Dia Ultra Crystallized Copper (D.U.C.C.) is a high-purity copper conductor material developed by Mitsubishi Cable Industries. Its crystal grains are grown to many tens of times larger than those of ordinary pure copper, and the crystalline lattice is given unified directionality. The larger the crystal grains, the smaller the crystal grain boundary (boundary between individual crystals), thus providing greater benefit in terms of sound quality.
