I am constructing project based on Arduino Due pedalboard. I’ve got view questions:
1. SW1 – bypass. Why is PWM7 switched between this „x” (is it dilatation?) and the ground? Is this switching needed in correct working of the whole circuit?
2. SW2 and SW3? What are those switches responsible for? Are they needed for correct working?
3. IN_BUFFERED – in the output stage there is this branch which is not connected to anything. With what should it be connected?
4. What is jumper (JP1) needed for?
