The RCA connector[3] is a type of electrical connector commonly used to carry audio and video signals. The name RCA derives from the company Radio Corporation of America, which introduced the design in the 1930s.[4] The connector’s male plug and female jack are called RCA plug and RCA jack.
It is also called RCA phono connector[5] or phono connector.[6][7] The word phono in phono connector is an abbreviation of the word phonograph, because this connector was originally created to allow the connection of a phonograph turntable to a radio receiver. RCA jacks are often used in phono inputs, a set of input jacks usually located on the rear panel of a preamp, mixer or amplifier, especially on early radio sets, to which a phonograph or turntable is attached.
In some European countries such as France and Germany, the name cinch is still used as an antonomasia of the Chicago-based manufacturer Cinch,[8] for such a connector and socket.
