RCA plugs are more commonly known as cinch cables or phono plugs. RCA stands for Radio Corporation of America, the name of the company that designed this connector. The plugs can be red, white or yellow, depending on the type of audio or video signal that runs through the cable. They are often used for table top players, dual CD players, DJ mixers and certain PA mixers. They are also often used with various multimedia devices. You can choose between male plugs or female connectors.
