I have a 4 day old P12 and I’ve noticed that 100% of the time there is a hissing sound, possibly the fans, emanating from it. I wouldn’t say it’s loud but I can hear it from my listening position which is 10 ft away when on mute.
When everything is on stand-by the P12 is at about 15% load and reaches a peak of approx. 60%.
Is this expected behavior?
