A couple of questions about the OWL Pedal.
I saw in the schematic that there is no input protection for the codec. Since the amplifier is powered with 5V, is it possible to damage the codec with input signals greater than 3.6Vpp (±0.3V is the acceptable margin for the WM8731)?
And about the power supply, it seems that the USB_VBUS is connected to 5V through a jumper. What happen if I connect both the USB and 9VDC power supplies? Would the USB source be damaged?
This is just for convenience, I can remove the jumper when using it on the pedalboard.
