Hall Technologies GLI-RCA Stereo Audio Ground-Loop Isolator and Filter with RCA Connectors

Stereo Audio Ground-Loop Isolator & Filter with RCA connectors. Eliminates ground loop noise between any audio source such as DVD player, MP3 player, or notebook PC and audio equipment. Perfect frequency response of +.03 db from 20 to 20,000Hz. Uses proprietary audio transformers and filters for total elimination of any spurious buzz and hum in the audio. Do you hear hum or noise in your audio setup with certain inputs? Most people would answer yes, and that’s because in most installations the audio signals are not balanced. Professional equipment have balanced audio which uses a + and a - signal for each L/R side and therefore does not rely on ground. Any noise in the ground between the source of the Audio and what it is connected to be automatically ignored. On the other hand unbalanced signals, such as the one coming out of consumer equipment, have no reference other than building/AC ground. Line-level audio is a very tiny low-level signal, so any noise in AC ground, even as little as 0.004v, will be quite audible - yuck!
