Issue with KPA

Hi guys. Have a little problem with my KPA. I have KPA and adams a5x connected to it via XLR. And issue is when KPA is turned off, but monitors still on, i have very loud hum noise. When i play KPA its ok. And when i disconnect monitors and KPA, but monitors still on, hum vanishes. Is it normal? Thanks for response and sorry for my english.

Sounds like a ground loop, have you tried using the 3 ground lift switches in the back ?
