I have these active speakers (Edfier R1600T Plus), and until yesterday everything was normal. When turned off, they make that usual "thump" sound due to the amp discharging, which is fine.
But since yesterday, it's also making this brief "screeching" noise, unless I turn the volume knob all the way down before turning it off (still does the thump btw). It doesn't matter if the input is connected or not.
It still sounds fine, just like before, but I wonder what could be causing this new behavior all of a sudden?
The amp is based on a TDA2050, if that matters...
