Hi all !

My HSB4383 produces a "pop" sound in the sub woofer every 2-3 minutes. most of the times quite low in volume, although very annoying, and sometimes (1-2 times per night) a very load pop sound that is definitively scary.

This happens even if no sound source is connected to it, just the HSB4383 turned on and also when listening to AUX, DI, DVD etc, etc.

Is this a known issue and is there any cure for it ?
It is really annoying ;-/

Cheers !
