RCA cables, also known as phono cables, are a popular type of audio and video cable that have been around for decades. They are commonly bundled as a pair of two or a set of three, but did you know that they started off as just one cable to transfer sound to individual old-timey speakers?
The cool thing about RCA cables is that a single plug contains the two cables a speaker requires. The red cable does the same thing as the white cable, allowing you to add another speaker and create a stereo effect on top of doubling your power. Stereo sound can be split amongst your speakers for left and right audio in whatever way the sound team wanted to create a dynamic listening experience.
Many people wonder if they can plug RCA cables from their TVs directly into their speakers. The answer is yes, if the speaker is active thanks to its internal amplifier. However, a passive speaker cannot receive a direct RCA or aux cable, and they need an amplifier to connect to, which the TV also needs to be connected to.
Now, let’s not forget about the yellow cable, which is used for video transmission. The blue and green RCA plugs are used for other purposes, which are explained in another video on the channel.
Sometimes you may need an RCA to something else, like an auxiliary plug or an exclusive plug for a Super Nintendo. If you’re looking for a specific combination that you can’t find, you may want to consider using a converter. The signal traveling through the cables can be converted with a device called a converter, which is explained in another video on the channel.
In summary, RCA cables are a versatile and important type of audio and video cable that can be used for a wide variety of applications. Whether you need them for stereo sound or video transmission, they can be a great investment for any home entertainment system.
