If you’ve had the opportunity to set up your home audio system, there’s a good chance you’ve used RCA cables to connect audio sources, receivers/amplifiers and maybe even speakers. The RCA connector is how the RCA cable connects to the equipment.

RCA jacks have been around for many decades and can still be found in many modern audio/video devices. They support content through receivers, amplifiers, columns TVs, media centers, and even high-quality desktop sound cards.

While new forms of input/output connections have been developed (e.g. HDMI , optical, coaxial digital ), RCA jacks are still widely available. They exist in many audio/video sources such as CD players DVD players, VCRs, digital media players, turntables camcorders/camcorders, game consoles (eg Xbox, PlayStation, Wii) and more.

RCA is pronounced ahr • see • ey. RCA jacks are also called RCA jacks and phono jacks.

RCA Jack Physical Description

The RCA jack consists of a small round hole surrounded by metal.

The connector is usually color-coded, or the device has an adjacent colored bar that describes which RCA cable connects to which RCA connector.

How RCA cables and connectors are used

When used in conjunction with an RCA cable that has a male connector firmly seated in the jack, it becomes possible to transfer analog or digital information from an input source to an output destination.

The RCA connector can often be used to connect an analog output DVD player to the analog inputs on the back of the TV. However, RCA inputs can also be found on other devices and even on the front of the TV.

The red and white colors represent the right and left stereo channels, respectively. The yellow connection (composite cable) is used to deliver the video signal.

More information about RCA connectors

RCA technology was developed by Radio Corporation of America for connecting a turntable to an amplifier. Today, RCA connectors are commonly used to connect various components in many AV systems.

The main connections are plain red and white for the right and left stereo channels. Yellow is used for composite video while component video connections (usually green, blue, and red) can be found on more sophisticated equipment. Surround stereo systems may have additional colors for individual speaker channels.

The RCA jacks are even used for coaxial digital audio signals (coloured orange) or for connecting antennas. RCA cables are sometimes found in combination with an S-video connector (higher video quality than yellow composite). Ports are usually labeled to avoid color confusion.

If the audio equipment is turned on, a buzzing sound may occur when the end of the cable is connected to the RCA jack. This is because the signal connection is made before grounding, so it’s a good idea to unplug everything before working on cables.

RCA jacks are still in use today, probably due to a combination of ease of use, low manufacturing cost, reliability, and global acceptance.
