Digital data transfer requires precise impedance matching in both the cable and connectors. Manufactured entirely in the USA, Heimdall 2 AES/EBU cables are optimized for digital signal transfer and utilize a silver-plated OFC solid core conductor suspended in Nordost's patented precision double monofilament construction. It is built with XLR connectors to provide a 110 Ohm signal path for digital data. This results in clearly audible sound and musical benefits. The result is ultra-high speed - the cable is low-loss specially designed to deliver the best possible performance from today's high-resolution digital audio sources.
