QED Coaxial Audio Cable overview


Manufacturers Product Description

The Reference Digital Audio 40 utilises a carefully engineered geometry to achieve the precise characteristic impedance required for the maximum transfer of S/PDIF signals. Silver plated conductors have the bene t of lowering the resistance path for high frequencies that would otherwise be travelling in the conductor periphery and lost due to the "skin effect". Traditional RCA plugs used for S/PDIF connections are insuf cient due to characteristic impedance that is not even close to the 75 ohms required for perfect energy transfer. QED "Digiloc™" plugs by their innovative design are much more closely matched to the cable impedance reducing return loss by up to 1dB when compared to conventional RCA plugs to ensure optimal signal transfer and improved micro-timing of the audio signal
