ground loop ini terhasil dari AC line frequency apabila terdapat 2 ground connection yg berbeza antara kedua equipment. maksudnya disini contohnya anda mempunyai 2 amplifier, dan kedua amplifier ini di ground ke dasar bumi dengan cable yg berbeza. hasilnya anda akan kedengaran noise atau hum. untuk mengatasi masalah ini, anda cuba groundkan hanya 1 single point sahaja utk kesemua equipment anda. walau bagaimanapun jangan sesekali guna cable unbalanced ataupun cuba cut AC ground utk mengatasi masalah ini.
