Picture of DIY Passive Audio Mixer

I have wanted to make an audio mixer for a long time now, but I couldn't find one that would get two channels from one audio jack, so I made one! This mixer is passive, meaning it doesn't need power and it can be configured in Virtual DJ as an external mixer with a stereo to mono splitter. This is my first instructable, I don't usually make such guides but I thought I would give it a shot. If you make this project, be sure to share pictures because I want to see how you made it!

Step 1: Gather required components

To make this audio mixer, you will need:

2x 10k Potentiometers

2x 1k Resistors

2x Momentary switches or pushbuttons (the pic has only one because the other was being used)

2x TRS 3.5 mm audio jacks (you can find these in old mp3 players).

Several female to male and male to male wires

1x Breadboard

Breadboards are fpr prototyping not for the final use. you need to go get a pc board and solder everything. you can get one at Radio Shack(2760150) or order one from Jameco(2125042),Digi-key, or others. If you don't it will eventually fail and if you are using it for a gig, it will probably fail during a show.

Thanks for the suggestion, however I simply created it with a breadboard for demonstration purposes, and I have already disassembled it. Also, if I were to create this as a final product I wouldn't use cardboard and I would purchase matching potentiometers.

Do you mix left and right channel of a stereo source to a mono output ?

The mixer mixes left and right of a stereo source out to a stereo output, or it can be configured to output to a mono output.
