RCA connectors are such a common component within modern electronics that it’s hard to imagine that they’ve actually been around since the days of WW2. Although we don’t have any reliable sources on the name of the original inventors, we do know what they were originally created by RCA. (Which was then better known as the Radio Corporation of America.)
These connectors were originally meant to replace TRS Connectors as high fidelity systems began to gain popularity during the 1950s. However, TRS connectors – in both 3.5mm and 2.5mm sizes – are still very common today.
Over the years, the RCA connectors have been adapted for a number of practical and interesting purposes. Today, you can see RCA connectors being used for power sources, audio signals, video signals, RF transmission, and certain types of digital signals.
In audio applications, the RCA connectors are well known for the brief buzzing noise that is emitted as you plug them in. This is due to the fact that the “hot” inner connection is made before the “cold” outer connection.
With most applications, you will have one dedicated connector for each signal. So for a typical television signal, you’ll have one wire for video (yellow), one wire for right audio (red), and a third connector for (white) left audio. In order to prevent confusion during the connection process, these wires will usually be color coded.
