What is the longest cable I can use with the DD540?
We recommend that, for best results, all cables (coax and optical) are kept to the shortest lengths practical. It is not possible to say exactly what the maximum length of cable is that may be used, since that will depend on the quality and condition of the cable and also on the equipment at the other end. However, as a guide a maximum length of 5 metres (15 feet) is advisable for any cable connected to the DD540. In particular, we recommend that the DD540 is positioned near to your A/V amplifier and connected to it using short cables. Problems that may occur if a cable is too long are audio drop outs (occassional short periods of silence) or loss of audio altogether.
