RCA
— characteristic round connectors for a tulip-type plug; can be used in different interfaces, but "RCA input" usually means an analogue audio line input. Note that only one channel of audio can be transmitted through one analogue RCA connector; therefore, the number of such connectors corresponds to the number of channels supported by the device (for example, a stereo input consists of a pair of RCA jacks).
