Have a Klax cabaret that was 100% AOK before moving it; after a bumpy ride, it's buzzing loudly. I checked the obvious things - sound self test, ground wires that may have come loose, loose connections, etc. and no dice. All the sounds work properly too, it's just got that loud buzz over the top of everything.
I suspected possible interference from the monitor, but that might not be the case. Any ideas?
