FAQs
My Fusion system has a loud hum or noise coming from the speakers connected to my amplifier.
This is normally caused by introduced interference through the RCA cables connected from the stereo to the amplifier and is often referred to as a ground loop. It can be caused by numerous electric sources of interference such as refrigerators, power and ground cables, LED lights etc. You can spend a lot of time searching for the source, so prevention is the best course - do not run RCA cables near any electrical equipment or power/ground cable runs.
The quickest way to resolve this is by fitting ground loop isolators on all RCA cables - this is an inexpensive way to remove the unwanted noise.
