dis morning i'v been playing for few minute surroud black hole but a strange buzz was coming out from a speaker.I checked all the gain levels,db levels out but nothing changed.It was me forgetting the phantom power turned on yesterday 4 some recordings.I turned it off and tried again tha h8000 and nothing(for now) seems to be happened.But i 'm still ansious and worried that somehing have could happened.A few reflections from U might comfot me.Ciao!
