Hum or buzz in the speakers is usually caused by something external to the speakers which is coupling noise into the speaker system (either through the AC lines, cordless phone, wireless router, or directly from the source input). A common reason is that the entire system is set up such that a "ground loop" results. Basically, a ground loop occurs when the AC power grounds and the system signal grounds are not at the same electrical potential. Refer to our online Setup Guides for a list of things to try.
