White noise normal?

I just purchased two PB2000s and they both seem to make a white noise/hissing type sound when idle. Even disconnected from the avr the only way to get it to stop is to kill the power, it doesn't return when powered back on until it's been used. One also seems louder than the other.

A faint white noise at idle is normal - it should only be audible with your ear near the subwoofer - and not at the main listening position.

It means your power from the outlet is "dirty". Do you have anything else running in the house that would take a lot of juice? How old is the wiring? Is it properly grounded? Try adding a power conditioner and see if it makes a difference
