This is a simple active buffer module designed for Eurorack. All jacks are soldered directly to the PCB, so no wiring is requried. This is a very simple project which is appropriate for a DIY novice. The input jacks are normalized so that when nothing is plugged in, a jack takes it's input from the jack to it's left.
