typical rca cable An RCA cable/connector, also referred to as a phono connector or Cinch connector, is a standard type of cable used to transmit analog audio and composite-video signals between devices such as televisions, satellite or cable receivers, VCRs, game console systems, speakers and more. The term “RCA” derives from the Radio Corporation of America, which introduced the design by the early 1940s to allow monophonograph players to be connected to amplifiers. Typical RCA cables will have two or three color coded connectors. RCA audio cables have two connectors: red (right stereo) and white or black for left stereo. An additional third connector on an RCA cable will be yellow for composite video.

Below table shows color coding of RCA cable, connector and pinout in typical consumer equipment found in market.
