RCA Cables

An RCA cable, also known as a phono connector or Cinch connector, is a type of electrical cable commonly used to transmit analog audio and composite video signals between devices. The RCA acronym stands for Radio Corporation of America, the company that originally introduced the connector in the 1940s.

RCA cables typically consist of two or three color-coded connectors at each end, with the colors representing the type of signal being transmitted. The most common color codes are:

  1. Red: Right audio channel
  2. White or Black: Left audio channel
  3. Yellow: Composite video signal

These cables are widely used to connect various audio and video devices such as televisions, DVD players, stereo systems, and game consoles. While RCA cables are still in use today, they have been largely replaced by more advanced digital connection types, such as HDMI and optical cables, which can transmit higher-quality audio and video signals.
