Computer Speakers Hum Fix

I had been looking for a device that might fix my ongoing grounding hum issue. We have three bands at our church and my electric acoustic (brand not named) was the only one that had grounding hum issues. This device immediately remedied the problem--all is normal now, no hum. A great problem solver. A reasonable price for the results achieved.

We had a problem with a hum in our sound system. I could find no way to fix it, so I called in an expert and he said it was a ground loop problem and suggested this product. I plugged it in and there was just silence. Wow!! No more noise when showing something on the screen and no more buzz when playing a movie or video clip.

I do a lot of live webcasts of seminars. I often get a house feed with hum.  I cant try to fix it in post because it goes out live. This device fixed the hum giving me clean audio.

Great device, bought to fix a ground loop hum between my catv coax coming into the house and my other audio-video equipment. So now no more hum and the video reception quality did not degrade.

I was looking to replace my external speakers because of a hum. The usb model was the way to with a respectable brand name.

I only have one device that added a slight hum and after adding this isolator - it just went away. To be honest, I don't know if it was the older speakers or the headphones I was using but it fixed the problem. [I have received this product in exchange for my honest review.]

Purchased this because I was getting loud lingering hum in my subwoofer and speakers every time my wife used the hairdryer or the fridge compressor kicked on. No longer! If you've got AC line noise, this will filter it out.

small compact direct box used for eliminating hum in powered speakers. a must for all musicians/dj's. great price.

I have an Onkyo NR5008 serving as a preamp to a Parasound 2250 stereo amp driving my Left and Right channel Tekton Design Double Impact speakers (high sensitivity 4 ohm speakers). Due to the potential current draws, these are on separate 20 amp circuits. The Jensen CI-2RR removed all the hum without changing the tonal balance or shaving off the high frequencies based on REW measurements. Bought this based on the success I had with the Iso-Max Sub-2RR I use to connect the Onkyo with my 1,000 watt subwoofer amplifier (plugged into a third 20 amp circuit). Both Iso-Max units eliminated the hum without sonically damaging the signal which was not true for the less expensive isolating transformers I tried first.

We had a disturbing 60 cycle hum from our main speakers at church. Connected this unit in line with each speaker and no more hum. That's about all I need to say. I works as advertised
