What Is an RCA Plug?
RCA plugs are connectors used to transmit analog signals in audio equipment.
They facilitate the transfer and reception of audio signals, connecting devices like radios, record players, televisions, speakers, microphones, and headphones. An RCA plug typically has a metal cylindrical body with two or three metal pins at the end. Red and white plugs indicate the right and left audio channels, respectively, while a third, yellow plug, if present, serves as the ground.
RCA plugs are valued for their ability to convey analog signals with high fidelity, ensuring minimal loss in sound quality.
