Ground Loop Issues With Computer Studio Monitors

Had a heck of a time chasing down a buzzing sound when connection my powered studio monitors to my MacBook Pro. It ended up being a ground loop due to unbalanced connection since I was running 1/8” stereo plug to y cable 1/4” to XLR to each monitor. Connected this back and it just worked - no drivers, no white noise, no ground loop, just crystal clear audio in my monitors.

My first ground loop from computer audio card to powered monitor speakers was corrected by plugging the monitors in to the same outlet as the computer. Then I upgraded my video card to a much more powerful one and the buzz came back when the video card was churning. Back to the internet to find a solution and this product seemed to be my best bet. It worked like a charm, the buzz is gone again and I don't hear any degradation in sound quality. Highly recommend.

I needed a solution for removing ground loop noise in my studio. I needed to connect my Yamaha 01v mixer to my PC using the onboard line jack (-10db). When I plugged the mixer into the computer using the RCA outs from the board it caused a terrible ground loop and noise from the mains was sitting around -35db. When I added the Rolls HE18, the noise floor now sits at about -67db. A 32db reduction in noise and very tolerable for both demo recordings and online audio streaming. It also does unbalanced to balanced audio conversion, has 1/8, 1/4 and RCA jacks (1/8 is input only). Heavy duty build and feel. The passive electronic design saves the headache of having to accommodate yet another wall adapter.If you have a ground loop in your project studio. Buy this box. It works.

We have now 4 of this units in our rental stock! Theyre doing a fantastic job. If you have any ground loop issues on a HD-SDI Signal, thats exactly what gets you out of trouble!

We recently switched to HD, and apparently the high-def format is much more sensitive to ground loop issues. This box took care of that and produced a clean signal. It's a cheap and effective fix.

Finally a ground loop isolator which actually works !

These devices did what they are advertised to do…eliminate ground loop hum.

I've had a GPU ground loop problem for years and this solved it

Fantastic for the studio monitors.

I bought this for a desktop computer setup after hearing great things about Kali Studio Monitors. I had the Kali Audio IN-5 monitor spears for several months. Now that I have the subwoofer the experience is even better! I'm using a headphone jack to RCA connecting the subwoofer to my motherboard (PC). Then use XLR cables to connect to my Speakers. The bass for gaming is incredible. Optional foot pedal switch input that lets you turn it off easily when you want to be stealthy.
