8 Input Passive Mixer

I built this to use in my classroom so that I could have all of the kids playing ipads simultaneously out of one speaker, instead of trying to use the iPad speakers (which is a non-starter). Each of the 8 input channels has volume control, and mute switch (my favorite part!), and there is master volume in the middle the lights show which channels are currently turned on.
