The RCA phono connector—not to be confused with the phone connector—is a plug and jack combination typically used for analog audio and video signals. The phone plug consists an 8.3 mm (0.327 inch) centre pin with a 3.2 mm (0.126 inch) outer earth/ground shell. Contact is maintained by friction.
IN the 1930s, RCA introduced the phono connector as a way to connect a phonograph to a radio receiver. Today, it is widely uses for connecting audio and video components in consumer electronic products, including phonographic turntables, preamps, radio tuners, DVD/Blueray players and televisions.
