Around the basic symmetrical construction, the SPECIAL XS series features the highly unique "X-Shield" technology, patented by Tchernov. This combination of BRC copper foil and copper braid ensures even more noise protection and improves the overall characteristics of the cable. SPECIAL XS INTERCONNECT CABLES are the perfect mix of sound neutrality, sound signal transmission accuracy, exceptional noise protection, the best materials and highest manufacturing quality. The wave impedance is 110 Ohm which enables analog as well as digital audio transmission. The SPECIAL INTERCONNECT CABLES are available on spools (SPECIAL XS IC), terminated lengths for analog audio in RCA and XLR (SPECIAL IC RCA and SPECIAL IC XLR) as well as in terminated lengths for digital AES/EBU audio (SPECIAL IC AES/EBU).
