Question about Audio Players & Recorders
Subwoofer suddenly makes loud buzzing sound when system is off, and air blows through hole in bottom of sub. Noise goes away when turned off. It comes back later for ** reason. Sub works fine when whole system is in use. I tried unplugging power supply form sub and receiver in hopes of resetting sub, ** luck. Is it the sub or something else.
Need a schematic for a sony sawmsp1 active subwoofer....anyone????

The circuit that should be turning the sub on and off based upon the presence of an audio signal is not working correctly and the sub is trying to reproduce 60 cycle hum. The unit needs service.
