I don’t have many other pedals so the sum of the current draws according to the manufacturers is less than the power supply limit. I scoped the 9V line but it looked flat… maybe the resolution isn’t high enough because there has to be something present that’s causing the humming. I think I will switch to an isolated supply, but I just wanted to make sure this was expected behavior of the H9 and I did not receive a defective unit.
