When any of the outputs 5-8 of my maudio profire 2626 are plugged into any channel on my mixing desk at full gain input, there is a humming noise when the mixer is turned on before the maudio.
This doesn't happen on channels 1-4.
This happens even when the maudio is not plugged in at all.
The noise sometimes changes pitch, like an airplane taking off.
As soon as I turn the power of the maudio on, the noise disappears.
See attached screenshot of EQ and wav file of the noise and how it turns off when maudio is turned on.
