RCA connector

An RCA connector (either RCA phono connector or Phono connector) is a type of electrical connector generally 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.

Male plug and female jack connectors are called RCA plug and RCA jack. The word phono is an abbreviation for the word phono connector in phonograph, as this connector was originally created to allow the connection of the phonograph turntable to a radio receiver.

RCA jacks are often used on phono inputs, a set of input jacks often found on the rear panel of a preamp, mixer or amplifier, especially in early radio sets to which a phonograph or turntable was connected.

The biggest problem of RCA connectors is that the live end of the male connector that carries the signal comes into contact with the female part without touching the reference end on the outside.

In working devices, when the connector is disconnected and inserted, it causes a short-term loud sound, and in some cases, the device breaks down. For this reason, it is inconvenient to disconnect and connect the RCA connector while the device is operating.
