Connect How To: Stereo Adapter, 1/4″ or 1/8″ Plug to two RCA plugs

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 thereĀ 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.

    Hello Church Sound Guy,

    Thought it would be a simple matter to hook up a pair of old harman/kardon computer speakers to the latest computer. Baffeled when I saw the two conductors in each speaker cable instead of the single conductor I was expecting. As you might realize I don’t do this very often. Your diagram has set me straight. Will use the speakers off the computer for my wife’s IPad.

    Thanks,
    Frank
