The RCA plug may be as familiar to other people as mini-jack plugs, as they are used frequently in Hi-Fi and home audio equipment. The acronym RCA stands for Radio Corporation of America and is the body responsible for developing this connection. They instigated the replacement of 1/4″ TRS Jack connections on Phonographs in the 1940s, to allow them to be connected to amplifiers, hence why this connection type is also called a Phono connection.

The RCA is an unbalanced, mono connection commonly found on DJ mixers, Hi-Fi equipment, audio interfaces, and frequently on the ‘tape in’ and ‘tape out’ connections on mixing desks and other devices.

The male RCA plug consists of a central pin measuring approximately two millimeters in diameter, and an outer shell whose inside diameter is about six mm. The plug shell is slotted rather than threaded, to facilitate quick insertion to, and removal from, the female jack or receptacle.

When connecting an RCA to 1/4 adapter, physical pressure is maintained between the slotted shell of the plug and the smooth cylindrical barrel of the jack. The plug shell is connected to the coaxial cable’s outer conductor, or shield, generally at electrical ground.
