Bose Companion 50
My speaker setup is plugged into my scarlett interfacte (which I used for recording), which is plugged into my laptop computer. Even the sound is switched off and the sound level is at zero for my speaker system it makes a loud noise when I turn on the power. It makes the same kind of noise my previous speakers used to make when I forgot to turn them off and then turned the power on. Only I hear I don't see anything to turn them on and off with except the round volume button (which lights up for a couple of seconds when I turn the power on and then goes off again).
Any ideas please, as this cannot be very good for the speakers?
