RCA connectors, also known as phono connectors, are a type of audio and video connector commonly used in consumer electronics. They are a simple and inexpensive way to connect devices such as TVs, DVD players, and audio equipment. RCA connectors have a distinctive design, with a small, cylindrical connector typically red for the right audio channel, and white or black for the left audio channel or video channel. They are often used to connect audio equipment to a home theater receiver, or to connect a TV to a cable or satellite box. RCA connectors are not as robust as XLR connectors and can be prone to corrosion, which can cause a loss of signal quality over time.
