With the technological advances seen in the 1990's, consumers have been able to create home entertainment systems that have cinema-level quality. A common issue that arises, however is stereo hum in the surround-sound speakers. This hum is commonly created by the peripheries of the entertainment system being plugged in to different outlets in the home that have varying levels of ground in the plug. The end-result of the variance of the grounding level of the plugs creates 60 Hz interference that results in the audio hum.
Instructions
1. Unplug all home entertainment components from their power source.
2. Plug the stereo equipment in to a power surge adapter that has multiple plugs on the cord.
3. Turn on the stereo.
4. Connect each component of the home entertainment center to the new power strip. Once all connections are made, turn on all of the entertainment center components, and the humming noise you heard before will be gone.
