Why do many powered studio monitor speakers have a low level audible background noise?
This is an issue with many big and popular brand monitors like KRK, Yamaha, JBL, Alesis and many others, even top end brands like Focal.
Time for some investigation on the KRK Rokit 6 studio monitor speakers to track down where the noise is coming from.
NOTE: Not all monitors have this issue, many much higher end ones may not. It pays to check this first if you are going to spend decent money on studio monitors, as you may find it annoying.
Service manual and schematic for the Rokit G6:
