Manufacturer Part #: GLI1-X1

What is a ground loop?
Listen closely to your speakers. Do you hear a hum? This is a typical issue with home audio that can plague nearly every speaker or audio system. For example, when you connect your speakers to your computer, power from your home outlets try to balance the amount of electricity being used. This change of balance results in your speakers "hum."
The ground loop isolator stops this hum by making a break between your power and audio equipment. Doing so ensures there is no path for current from an electrical imbalance to flow.
Installation couldn't be easier. Make sure that your computer and/or audio equipment is turned off. Connect your RCA audio cables in their appropriate ports (right and left audio), and then connect the related cables to your stereo or audio equipment, and you're done. There's no need to worry about a power source or other wires to connect.
Each fine Xitel product includes a full 1 year warranty from the date of purchase. So if you're suffering intensely from the horror ridden hum emanating from your audio system, make the right choice and add a ground loop isolator to silence that buzz.
