Connect How To: Stereo Plug

Here is a basic diagram on how to wire a 1/4″ or 1/8″ (3.5 mm) stereo plug. If you are going to use it for speaker connections, you do not want to use shielded cable.

Being an ex-band roadie and now a church sound guy, there have been times when I have had to make adapters on the fly. Seems like there are always two things that need to be connected with different types of connections, and troubleshooting problems can be difficult if you don’t know what hooks up to what. Here are some wiring diagrams of adapters I deal with quite a bit.

Stereo Adapter 1/4" - (2)RCA

This adapter works well with connecting a headphone output with a line input or recording input. There are even some stereo speakers that have RCA type input jacks.

As you can see, I have illustrated the right wire as being red and the left wire as being white. The wires aren’t typically those colors, but the casings usually are, and those colors are standard on all the stereo equipment that I’ve ever seen.

Although this diagram illustrates how to wire a 1/4″ stereo plug, it’s the same diagram for a 1/8″ (3.5mm), only smaller.
