The ground isolator is used as an audio filter and eliminates hum and audio noise. Such noise often occurs when connecting audio devices that are connected to the mains with earthing contact plugs, e.g. computers and active boxes, TVs and AV receivers, PCs and monitors. The ground isolation filter can also eliminate unwanted noise from audio connections in vehicles. In the car, sound interference occurs when music is played from a smartphone and it is charging at the same time. The ATG00101 has true galvanic isolation. It is connected anywhere between the two devices using the short audio cable (3.5 mm) jack supplied. Due to its compact dimensions of 60 x 20 x 20 mm, it is easy to stow away.
