Devices mount the socket ( female jack), consisting of a central hole with a ring of metal around it. The ring is often segmented to provide spring gripping pressure when mated. In the most normal use, cables have a standard plug on each end, consisting of a central male connector, surrounded by a ring. Other uses RCA female jacks used for YPbPr component video output Composite video cable with RCA male plugs for the Xbox 360 Refinement of the RCA connectors came with later designs, although they remained compatible. In the 1950s, RCA connectors began to replace the older quarter-inch ( 1⁄ 4 inch) phone connectors for many other applications in the consumer audio world when component high-fidelity systems started becoming popular during the transistor revolution. Three lower-cost 1939 television models had an audio output connector on their rear panel instead of an integrated amplifier and speaker: RCA TT-5, Westinghouse WRT-700, GE HM-171. In 1939, RCA introduced two radio- television floor consoles (TRK-9, TRK-12) which used the same internal connection concept but the audio output of the television chassis was connected to the radio/amplifier chassis via a male to male cable. RCA later marketed a special turntable for 45 RPM records, the model 9JY. The connector was labeled on the back of radio with one of the following terms: " Victrola", " Phono", "Pick-up", "Television". īy no later than 1938, RCA migrated the female connector to the rear panel of many of their desktop AM radio models to allow customers an easy method to attach an external phonograph or television at a later date. Originally, the concept was intended as an easy method to unhook sources while troubleshooting the console during servicing. In the U-109, the internal amplifier chassis had female connectors which accepted male cables from the internal radio chassis and built-in phonograph player. In 1937, it was used inside a RCA model U-109 radio- phonograph and model R-97 phonograph. The following dates were derived from historical RCA documentation.īy no later than 1937, RCA introduced this connector. The exact release date of this connector is still a little vague. Tag reads "An inexpensive RCA Victor record player will make a fine Victrola of this radio. History Rear panel of a 1939 RCA model 45EM vacuum tube desktop AM radio with a female RCA jack. 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. 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. It is also called RCA phono connector or phono connector. The connectors male plug and female jack are called RCA plug and RCA jack. The name RCA derives from the company Radio Corporation of America, which introduced the design in the 1930s. The RCA connector is a type of electrical connector commonly used to carry audio and video signals. The bottom line is that it is quite common for people to be unaware of the differences in signal types with respect to the "strength" of the associated signals, and assume that everything is interchangeable as long as the connections can be made.RCA plugs for composite video (yellow) and stereo audio (white and red) And you only need the proper cables and/or adapters to connect to other gear. Without seeing the piece of gear you're talking about, and/or reading the manual, I'm guessing that the signal it expects is input level. They simply take the signal type/level that is fed to them, and deliver,it to the other end. In other words, cables do not convert signal levels from one to the other. But it's the gear that determines the signal type/level, not the cable. Some turntables only send a phono level signal, and that signal would need to be (pre)amplified up to line level to be useful in some scenarios. In either case, the RCA output jacks carry the signal. But it also has a selector switch that allows switching between a phono level signal or a line level signal. The term "phono" is often used to describe the physical connectors and/or the signal type.įor example, I have a turntable with RCA output jacks. There are two separate but related factors to consider.
