How to Connect a 3.5 mm Stereo Connector to an RCA Connector

Keeping with the theme of technology, I will present a tutorial on how to connect a 3.5 mm stereo plug to a RCA cable. As you may know, cables and wires are vital parts of electronic devices. They allow the flow of electricity and data. In case you have any question about what these two connections are, I will quickly explain them. A 3.5 mm stereo connector is an input plug commonly seen in headphones and speakers. Connecting it to a 3.5 mm port will allow headphones or speakers to function as they do and deliver sound.

This is how it looks like:

A RCA connector is a cable that forks into three-colored input plugs. The iconic red, white and yellow colors in the plugs are indicators that represent the audio or video function of each of the plug. More of those functions will be discussed later.

Below is an image of it:

The task of connecting the two plugs together may seem simple enough, but I think some people may find it useful to have step-by-step instructions on how to do this. Personally, I had experiences in the past where such knowledge would have been very helpful and I could have avoided some errors, like purchasing the wrong adapter. So why do we need to connect the two plugs in the first place? The answer is pretty simple. Devices, like televisions and game consoles, do not always have 3.5 mm ports to plug headphones or speakers to. Many times, these devices output sound through specific ports that can usually be connected with a RCA cable. The RCA cable would then have to be attached to the headphones or speakers through an adapter in order to listen to the sound.

Please note that there are several ways to go about connecting the two connectors. This guide is merely one way to do it. These are what you will need:

Item A
3.5 mm stereo plug (connecting to headphones or speakers)

Item B
RCA connector (connecting to a device like a television or a game console)

Item C (adapter)
3.5 mm stereo port to RCA port adapter

3.5 mm stereo plug to RCA port adapter and 3.5 mm stereo coupler


1) Make sure item B (RCA connector) is connected to the device.

2) Connect item B (RCA connector) to item C (adapter).* To do this, locate the red and white plugs from the RCA cable and connect it to the corresponding red and white ports on the adapter. Red plug on red port. White plug on white port. The yellow plug is for video output and will not be needed in this process.

*Note that if a 3.5 mm plug to RCA port adapter is at hand instead of the other adapter, one end of the 3.5 mm stereo coupler would have to be inserted to the 3.5 mm plug of that adapter. 

3) Connect item C (adapter) to item A (3.5 mm stereo plug ). This is done by simply inserting the 3.5 mm plug to the 3.5 mm port.

4) Turn on the device and enjoy the sound.

When dealing with electronic devices, compatibility is a recurring issue. It is common to have ports and cables that do not connect. That is why adapters are so essential. There are all kinds of connection standards these days. There are USB connections, VGA connections, DVI connections, S-Video connections, HDMI connections and many more. Fortunately, there are many adapter combinations as well to aid in your connection needs.
