Nordost Heimdall 2 Digital Interconnect

Digital data transfer demands precise impedance matching in both cable and connectors. Manufactured entirely in the USA, the Heimdall 2 S/PDIF and AES/EBU cables are optimized for digital signal transfer and use a silver-plated OFC solid core conductor suspended in our proprietary, precision Dual Mono-Filament construction. In the S/PIDF cable, this technology is combined with combination BNC/RCA connectors, providing a true 75 Ohm signal path which answers the demand for the precise tolerance needed for clocking and dealing with digital output. Whereas the AES/EBU cable is constructed with impedance matched XLR connectors, providing a true 110 Ohm signal path for digital data which results in clearly audible sonic and musical benefits. The result is an ultra high-speed, low-loss cable specifically designed to deliver the best possible performance from today’s high-resolution digital audio sources. They may only be “ones” and “zeros” but poor impedance matching has a dramatic impact on the accuracy with which they are passed from one electronic device to another. Nordost’s ultra-close tolerance digital transfer solutions deliver the goods, sonically and musically.
