Bought two of these, both produce noise through the speakers :(
Solves the problem! I had a problem with a ground loop between the computer's USB interface, an RME audio interface and a Lindell Audio Preamp/EQ. This little isolator completely solves the problem without any side effects that I can detect. I was a little worried that it would introduce more latency into the system, but HiFime assured me it wouldn't and measurements with CEntrance Latency Test Utility confirm that. Highly recommended!
I just wanted to pass along that this device works great with my Line 6 Helix. I had a lot of white noise coming from my PC. Mouse movements and crazy computer glitches. I needed this one due to the 8 usb channels the helix can do. All is well...and quiet!! Thanks!!
YES!!!! I have silenced my GA Z97 MX Gaming mobo which spews out noise to my UR242 via the USB (with nothing else connected between them whatsoever to make a ground loop, this was a pure USB noise/ground loop problem) despite marketing around their DAC-UP USB ports. Mind you, just about every computer I've had since after dual G4 400 powermacs have been noisy, even my 08 Mac Pro lets out a little noise through the audio channels. If you can't go optical, the Hifime High-Speed USB Isolator simply works. I can now grow my hair back. Any day now.
This works perfectly! My monitors have gone from unbearably noisy to dead quiet.
Using the Native Instruments Audio Kontrol 1 - 192KHz 24bit. Tried with phantom power enabled as well, no problems so far.
Thanks for an excellent product!
