Delta Series S/PDIF features a true balanced, twisted pair design. Ohno continuous cast copper, VTX™ (hollow core) conductors with expensive fluorocarbon dielectrics and braided shielding.

Shunyata Research’s exclusive KPIP™ process eliminates lengthy burn-in issues. The standard length of the cable is 1 meter. High-speed digital transmission is very different from audio frequency signal transmission and requires a different knowledge base and design criteria. Audio cable signal transmission is governed by the principles of inductance, capacitance, and resistance. By contrast, high-speed digital signals are governed by a principle known as ‘transmission line theory. The performance of a transmission line is governed by the characteristic impedance of the cable. Certain types of cable require a specific characteristic impedance to achieve optimal performance — for instance, cable TV coaxial cables are 75 ohms, while test equipment cables require 50-ohm cables. Modern audio and entertainment systems may have multiple digital connections, each with potentially different characteristic impedances. While the characteristic impedance is a critical factor in the optimal performance of digital cables, our research also indicates that the precision with which a digital cable is constructed has a significant impact on its performance.
