The development of large-scale multi-track production equipment for Direct Stream Digital (DSD) audio will besubstantially aided by the availability of a convenient multi-channel interface. DSD is the high-resolution 1-bitaudio coding system for the Super Audio CD consumer disc format. Existing multi-channel audio interconnectionand networking protocols are not easily able to support the high-frequency sample clock required by DSD. A newinterconnection type is introduced to provide reliable, low-latency, full-duplex transfer of 24 channels of DSD,using a single unscreened office networking cable. The interconnection transfers audio data using Ethernetphysical layer technology, whilst conveying a DSD sample clock over the same cable.
