The feedback, often times referred to as a buzzing sound, that is sometimes received from an audio or video device is called a ground loop. To solve this noise issue that can occur within the compartments of an audio or video mechanism it is best to use a ground loop isolator.

The isolation transformer can be connected to the system experiencing the ground loop. Once the isolator is connected it will work to break the ground path through cables that run between elements of the piece of equipment. The elimination of this noise matter can be extremely difficult to do away with so it may take a great deal of time and patience.

When an audio device receives a buzzing feedback it is often referred to as a ground loop. The humming noise that sometimes comes from speakers is a form of ground loop. This buzzing noise is caused by voltage prospective differences that are found at the ground point of the mechanism, i.e. a speaker or headphones.

A ground loop may transpire when more that one audio element is powered from different power outlets. When this takes places the hum or the buzz is what results and is heard through the audio device. When this takes place a ground loop isolator may be needed to repair the issue.
