Ground loop noise occurs when a radio system draws power from a power system.Ground loop noise can occur due to several reasons. This noise causes severe audio distortions thereby, making tuning and listening to the radio difficult. Ground loop noise manifests because ground cables do not possess perfect conductivity.Īs a result, noise filters into an audio receiver via the common ground point because it connects to various other electrical devices. It propagates through a radio system when the shield of the wire that connects to a receiver carries a combination of noise and audio signal to the ground system. Ground loop noise is nothing but static or noise that affects an audio output of a receiver.
Understanding the concept of ground loop noise is key to understanding the need for a ground loop isolator. What is Ground Loop Noise and what Causes it? You can construct your ground loop isolator all by yourself by using a few tools and materials that are available at your local hardware shop. Installing a ground loop isolator to your radio equipment may be the answer to your problem.ĭo I need a technical person to build a ground loop isolator? No, you do not. The good news is you don’t have to listen to poor radio reception for the rest of your life. It can also make you miss out on crucial conversations or headlines of the morning news. This constant whistle-like sound – also known as ground loop noise – can be annoying and may prevent you from enjoying your favorite jam. Sometimes you may experience static or distortion to the audio signal. The problem may become insignificant somewhere along the way.A DIY ground Loop Isolator may be your only solution to having a clear radio reception. There should be an improvement with all 3 devices on one charger and further improvements as the number of independent chargers is increased. I mean, you can always try it first and see whether the interference level bothers you.

This is pretty much the same kind of problem you get when using some of these small PC speakers with a 3.5 mm cable for audio and USB for power supply, and plugging both into the same computer.

Those are effectively in series with the respective output signal. There must be differences between the ground potentials of each device then. Now since we know that the USB ground potential at the PC and audio ground potential at the mixer are the same for all devices, these differences have got to end up somewhere. This is going to be different for each of them.
