Machine Gun Noise

    I have been using a rack version with no issues. Last Sunday I played an outdoor festival with generator power... near the end of the show the Kemper started making a very loud machine gun static noise every time I went up in volume . I have been unable to recreate this at home. I am wondering if anyone has had this issue..Could it be low voltage on the generator? Thanks

    I had an issue once where the Kemper made a loud continuous noise because all of the ground lifts were engaged/pressed in.Maybe try them by adding them one by one and see if it happens ?
