"The Noise Destroyer is a parallel AC filter- A classic Wall-Wart- which plugs into a "free" socket within the AC circuit. It consumes a tiny amount (about 0.25ma) of current while it goes about getting rid of the RFI and EMI polluting the AC circuit, providing you with a lower noise floor resulting in better audio and video performance. The filter system is not current limiting, nor does it have any adverse effect on dynamics. "
