1 to 4 RCA cables are the most common way to split an outgoing signal into its composite video and stereo audio parts. While nearly all modern televisions connect to their content providing sources through an HMDI cable, RCA cables are still a valid alternative in many cases if one that involves a few more wires. Unlike the signal produced by an HDMI cable, the signal from an RCA cable is analog and can be split somewhat more easily than its high.

1 to 4 RCA cables are a series of male connectors, which separates the provided signal into its component parts. A standard set of RCA cables provides three connectors, one for video and two for audio. A high definition RCA cable consists of three outputs for component video, two for stereo audio and one for digital audio. RCA cables can also be great for use in stereo systems in situation where the signal is degrading before it reaches everywhere it needs to be. RCA cables are much thicker than traditional audio cables which results in a substantially smaller amount of signal loss at greater distances.

1 to 4 RCA cables do have a few disadvantages to consider which make it the wrong choice in a few situations. One issue that may occur is that the connection often comes in in sections which can create a loud buzz. Another issue to consider is that each RCA connection needs its own plug, possibly creating a bottleneck of available ports.

Additional uses for a 1 to 4 RCA cables include an RF connector, a power connector and a connector for loud speakers. RCA cables can come in several varieties which provide between one and four channels of output. Quality one to four channel RCA cables contain gold plated connectors which are designed to reduce signal degradation, decrease the chance of corrosion while still providing superior performance.
