QED Reference Digital Audio 40 COAX 3m

The Reference Digital Audio 40 not only features a carefully designed conductor geometry to ensure the impedance required for optimal transmission of S/PDIF signals. Additionally, its silver-plated copper conductors are better at conducting higher frequencies. These frequencies are otherwise only transmitted at the edge of the conductor, which can lead to signal losses due to the skin effect. Finally, QED's Digiloc RCA connectors are optimally matched to the cable impedance of 75 ohms, reducing reflection losses by up to 1 dB compared to conventional RCA connectors, ensuring optimal transmission and improved micro-timing of the audio signal.
