Audio systems with coaxial input
prices on 2 modelsCoaxial input
— a variation of the S/PDIF interface that uses data transmission over an electrical cable with an RCA connector. Do not confuse this connector with a "regular" RCA input (see the relevant paragraph): in this case, the signal is transmitted in digital format over a single cable, which is enough even to work with multi-channel sound. S/PDIF is one of the most popular digital audio interfaces used in modern audio and video equipment; its electrical version is not as resistant to interference as the optical one, but does not require special care in handling cables. The coaxial input allows the audio system to work with external sound sources using this interface — in other words, to play the role of active acoustics.
