If the digital cable supplied is not long enough to reach your home audio system, you may replace it with a longer cable of up to 100 feet designed for video or digital audio use, which may be purchased from your local electronics dealer. If you require a connection longer than 100 feet, there is a possibility of some loss in audio quality due to degradation of the signal as it travels a longer distance. Do not use RCA-type audio interconnect cables that are not designated for video or digital use. Try to avoid using a longer USB cable, in order to avoid degradation of the data.
