QuestionHeard these take away from your sound
Asked 5 years ago by Chozen.
- Answer Actually 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.

QuestionWhy does this devise kill 70% of my bass?
Asked 6 years ago by Mike.
- Answer I 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.

QuestionDoes this device need power? I can't see the specs to see the power voltage and how to connect.
Asked 8 years ago by Jeff.
- Answer No power connection. Connect RCAs to unit and unit to amp and than connect connection from unit to ground and done.

QuestionWhy wouldn’t this work on a home audio system?
Asked 5 years ago by Jake.
- Answer I’m not sure why. I just hooked it up between two of my audio components with the problematic component placed after the ground loop isolator and it cleared up the buzzing sound.

QuestionDo I need three of these? One for the subwoofer connection, one for the channel one and two connection,one for the channel 3 and 4 connection. I have a 5 channel amp. Thanks
Asked 6 years ago by Ed.
- Answer Short answer: No. The ground loop isolator is designed to connect line level outputs to inputs...for example from a CD player line level output to an amplifier line level input, both of which would have plug-in (115 volt AC) power supplies. The amplifier output to speakers would not benefit from an isolator unless the speaker is powered and plugged into a 115 V outlet. So if the speakers are passive and powered by your 5 channel amp, the isolator is not needed. Moreover, if you are feeding signal into the amplifier from a battery powered MP3 player (or similar device) the isolator is not needed. It is only helpful when connecting two devices that each have plug-in 115 V AC power supplies. Finally you may find that the isolator attenuates the bass end of the audio signal, so if you are not pestered by a 60 hz hum, don't use the isolator.

QuestionDo you need to hook up the ground wires? Or doesn’t the ground wires make a difference?
Asked 6 years ago by Mikey35.
- Answer Did not hookup my ground wire and it still worked just fine no more winding sound.
