Block That Hum! Getting loud hum from your subwoofer or speakers? You likely have a "ground loop". This is almost always caused by your incoming cable TV feed. The Axiom no loss chrome-plated ground isolator effectively blocks the hum-causing voltage difference between your cable TV feed and your A/V system, thus eliminating the hum. Note: this cannot be used with satellite dish systems. The ground isolator connects easily between your incoming cable TV feed and your cable TV set-top box. Also usable with Cable Card HDTV sets.
