The QED Reference Digital Audio 40 cable carries S/PDIF digital audio through a 75 Ω coaxial design, with geometry that achieves the characteristic impedance required for signal transmission. Its central conductor, made from 99.999% pure silver-plated, oxygen-free copper, has a foamed polyethylene dielectric, while the 99.999% pure OFC copper double braid provides 100% electromagnetic shielding.
QED Digiloc RCA plugs feature 24-karat gold-plated, high-purity copper contacts, a hollow centre pin and a low eddy-current design. Their fit is matched to the 75 Ω impedance to reduce return loss.
