RCA is an acronym for Radio Corporation of America, as the RCA connector was invented by this company.

RCA is also known as the AV terminal, or AV connector, and is found on almost all televisions and DVD players. The RCA connector is by far the most common type of audio/video terminal. This two-wire connector was invented by RCA Recording in the days of the radio, and is also known by its older, stranger name, the "turntable" connector.

Signal Transmission Method

RCA terminals use coaxial transmission of signals, the central axis is used to transmit signals, the outer edge of the circle of the contact layer is used for grounding, can be used to transmit digital audio signals and analog video signals.RCA audio terminals are generally in pairs with different color labeling: the right channel with red, the left channel with black or white. Sometimes, the center and surround channel connectors will be marked with other colors to facilitate the distinction when wiring, but all the RCA connectors in the entire system are the same in terms of electrical performance. In general, RCA stereo audio cables are grouped for the left and right channels, with one wire per channel in appearance.
