ViaBlue SC-4 Silver Series speaker cables have stranded conductors plated with genuine silver and a special silver-copper mixture for powerful accentuation of the bass range. The cables ends are crimped with low-oxygen-content, gold-plated OFC copper crimp thimbles. On these appropriate ends are mounted the ViaBlue TS Series loudspeaker plug-in connections plated with genuine gold. SC-4 speaker cables have a transparent and three-dimensional acoustics and a brilliant, airy quality in the high range. Clean lows and basses homogeneously round out the acoustic pattern. Technically, all of the frequency ranges are cleanly and realistically represented and reproduced in a linear fashion. The four 4 mm2 leads of the SC-4 speaker cables each consist of seven-stranded lays, with a total of 896 individual wire conductors. In order to customize the sound range for the individual frequency ranges, two of the four leads are totally silver-plated and the other two are silver/copper mixture leads, where each single lead has five strands plated with genuine silver for accurate reproduction of the treble range and two strands with pure copper strands for powerful accentuation of the bass. The basic burn-in time of the SC-4 speaker cables is approx. 22-24 hours. The total burn-in time is approx. 42-44 hours. (Exact times depend on temperature and location)
