Product Description

QED Reference Digital Audio 40 (available in 0.6m, 1m or 3m length) utilises a carefully engineered geometry to achieve the precise characteristic impedance required for the maximum transfer of S/PDIF signals.

Designed to offer better performance than QED's Performance Digital cable, it connects your DVD player, CD player etc to a DAC or AV amplifier input for a high performance digital audio connection.

Delivers audible sonic improvements

Silver plated conductors deliver a low resistance path for high frequencies and QED "Digiloc" plugs more closely match the cable's characteristic impedance, reducing return loss compared to conventional RCA plugs for optimal signal transfer and improved micro-timing.

Through the use of factory controlled geometry and low permittivity foamed polyethylene dielectrics, Reference Digital Audio 40 maintains the correct characteristic impedance to match the transmission line between digital source and sink precisely. This makes for a very low jitter signal transfer for clearly audible sonic improvements.

75Ω Impedance matched Digiloc RCA plugs

Domestic S/PDIF interfaces use the traditional RCA phono connector which is not impedance matched to the 75Ω transmission line. This causes measurable insertion loss and an increase in jitter due to signal reflections at the connector boundaries.

The all new Digiloc RCA plugs are more closely impedance matched than ever before and measurements have shown, reduce insertion loss by up to 1.2dB compared to ordinary RCA plugs.

Triple Layer Electromagnetic Shielding

A dual layer closely woven 99.999% OFC shield braid and aluminium mylar wrap with 100% coverage comprise a triple layer electromagnetic shield coaxially spaced around the central signal carrier within a foamed polyethylene dielectric.

This ensures that interference signals induced by nearby high current noise sources do not contribute to higher signal jitter than would otherwise be the case. By the same token the shielding prevents unwanted voltage induced interference escaping the cable which might affect nearby analogue signal carriers.
