A: AnswerActually a ground loop audio isolator enhances sound quality by eliminating AC hum. Ground loop problems are caused by small voltage differences that normally exist between the ‘grounds’ at the send and receive ends of a audio signal cable. In an unbalanced interface (consumer audio), this ground voltage difference directly adds to the signal. This generally produces hum or buzz in audio. In a balanced interface (professional audio), the ground voltage difference may reveal inadequate common-mode rejection at the input stage of the equipment (Bad Ground ) or other design defects. A ground isolator in the signal path is the fundamentally correct way to eliminate system ground loop problems. A transformer does this by magnetically coupling the signal across an electrically insulated barrier wh9ich blocks electrical noise and creates a clean audio signal between pre-amp and amplifier and is connected as depicted in photo.Answered by Ezdollarz
Q: QuestionWhy does this devise kill 70% of my bass?(2 answers)
A: AnswerI think the transformer does not provide a flat frequency response down to the 20-50 hz or lower range. You could try to flatten the curve with bass boost. It may be that a higher quality/price isolator would provide a flatter response on the bass end, but i haven't tested this hypothesis yet.Answered by hombreretirado
