FeinTech ATG00101 Audio Ground Loop Isolator Filter Suppressor Noise 3.5 mm Jack Stereo Cable, Black

I bought this specifically to fix an incredibly annoying issue with my setup. I was getting a constant buzzing sound from my Sony Bravia 9 whenever I connected the S-Center Out cable to my soundbar. It made using Sony’s Acoustic Center Sync feature basically impossible. I plugged this FeinTech isolator into the S-Center port, and the difference was night and day. The buzzing stopped immediately. It completely filtered out the ground loop noise without affecting the audio quality or sync. If you are dealing with that dreaded hum on a Sony setup, this is the fix. It’s a small adapter, but it saved me a lot of frustration.

AaaamazingGGGGGG! is perfect to Block interferences in sound Recording

Funka perfekt. Gör det den skall göra.

Had a constant buzzing sound over one of my two pc’s on my stereo. Placed this device between the buzzing pc and the speakers and It solved it completely.

Mein Setup im Arbeitszimmer besteht aus Cyrus Verstärker + Wharfedale Diamond Boxen + Wiim Mini. Brummschleife an einer Box; auf Dauer sehr störend. Mantelstrom-Filter zwischen Wiim und Verstärker und das Brummen ist weg. Himmlische Ruhe, ohne dass ich irgendeine Klangeinbuße wahrnehme.
