Eurorack L-1 AC/DC Mixer

via L-1: "Mixer has 4 inputs which can be mixed in pairs and all together. Inputs are AC or DC coupled in pairs by switches. Potentiometers attenuate gain, unity gain at the center their range, max gain = 2. So it is amplifying mixer. PCB made for 15mm Alpha pots with clear shaft, so funny 3mm LEDs can be mounted. Several options are for opamps. I've choose OP270 because of their great DC precision and sound quality. TL072 is cheap budget variant. OPA2604 has sound quality a bit better than OP270 but DC precision as in TL072. The device can work from 12V and 15V..."
