Topic: Fireface 800 whistling
Hi to all, since some months my RME Fireface 800 started to produce this high pitch noise from inside in the PSU Area. This noise can go on also for one hour and then stop for the rest of the session, if I keep using the card for 6/8 hours a day, this noise disappear, if I keep the unit off for a couple of days, it starts again with his normal behavior. The noise is not audible from headphones or on monitors but sometimes it can be "written" on the recorded file at very low volume, here is a video from inside the unit.
Has anyone ever experienced anything like that? Solutions?
