Computer 60 Cycle Hum Not Speakers

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

Installed and removed 60 cycle Hum from Audio

Had a 60 cycle hum in my audio/video system and narrowed It down to the Blu-Ray player and cable box were causing a ground loop. Installed the Jensen ISO-Max VRD-1FF on the cable line before the box and it worked - no more hum. Much thanks to Jensen and B&H.

I purchased one of these earlier and use it on my home entertainment system. The house has issues with 60 cycle hum which my entertainment system was picking up. The AV-HK1 eliminates this nasty hum. For this application it works great. I'm sure it works just as well in other environments.

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'm a weirdo who seems to alternate from macbook pro's to Dell XPS's every other cycle. I my last computer for the last 4 years has been a Dell XPS, but I wasn't thrilled with the new keyboard layout, so I'm back to a mabook pro! It's quick and easy. Enjoying it!

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.
