I have an Anthem A5 and when I turn it on there is a slight "hum" if you put your ear close to it. From 3 feet away it’s unnoticeable. It's in the amp, not in the speakers. Is this normal?
Is your system connected to a cable box or satalite dish via RCA interconnects? Sometimes the cable companies don't ground their outside connections to the home. This can cause a hum that will heard through the speakers.
