ADUM3160 Isolation Module Digital Signal Isolation Module Audio Power Isolator USB to USB Audio Signal Isolator 12Mbps Adum3160 1500V

I have a Cox cable system feeding my TV. The cable box is grounded to the incoming coax cable. For whatever reason, the Cox ground is at a different voltage potential than my house ground, causing (loud) audio hum for any output device connected to my NUC.On the NUC, I run Roon music player. My audio path is NUC USB out to an AudioQuest Dragonfly Red, and from there directly to my power amplifiers.The only problem I had with this ground loop interrupter is that the back of the NUC is crowded, and the broad "shoulders" of this device prevented me from plugging it directly into the NUC (physical interference). My solution was to plug in another device that would fit. So my signal chain is now: AudioQuest Jitterbug (plugged directly into the NUC) + this ADUM isolater (plugged into the Jitterbug + AudioQuest Dragonfly Red (plugged into the isolator) + 1/8" analog stereo plug to dual RCA outputs (plugged into the Dragonfly).And before anyone jumps on me, yes - I've read the reports saying that the Jitterbug does nothing. In my case, I'm just using it as a spacer, so I don't care if it works or not (I bought mine used on eBay for virtually nothing).This leaves a train of devices hanging off of the delicate NUC USB outlet port. To prevent NUC damage, I've used a couple of wooden spacers to support the Dragonfly and remove stress from the NUC motherboard.So, from an electrical standpoint, the ADUM ground-plane isolator works GREAT. For the price, I recommend it highly!Boomzilla (aka Glenn Young)

I read the other reviews saying it can't pass enough current to power most devices, and thought I was fine because my USB device had external power. However, it was not recognized on my PC when inserting the isolator between the device and PC.I bought it to prevent a ground loop in my guitar processor (Boss GT-1000CORE) when connecting it to my PC via USB and also to the same power strip that the computer uses. Thought this would be a slam dunk since the processor has its own power supply.

Hi everyone. This device solved the ground loop noise problem in my PC desktop 2.1 sound setup.My setup before: PC (3 prong) -> Qudelix-5K Usb DAC -> Pre-amp (2 prong) -> Power-amp (2 prong) -> 8"SUB (3 prong) *Ground loop issue presents when the 3 prong plug SUB is connected.After adding this Usb isolator. I have no more static noise thru the SPEAKERS when no sound is being played. And best part is that high-pitched noise thru the SPEAKERS when GPU is under load is gone.I tested the bass response before and after. I did not hear any difference.I use a low power portable DAC in my setup. So your milage may vary depending on your choice of DAC.

Successful eliminated the annoying ground loop noise from my Karaoke speaker which is caused by the wireless microphone receiver sharing the same usb power bank with the BT receiver. Surprisingly, it’s the cheapest price I could find for this type of device and it gets the job done. Great buy!

The reviews on this item are all over the place. At least partly this appears to be connected to unrealistic expectations.First, let's get the basics out of the way. This is a cheap Chinese device and quality control is accordingly. So, yes some percentage will have LEDs not working or not work at all. There is a reason I am not giving it 5 stars.Second, the seller is not promising that you can charge your phone though this thing or run any device that draws a lot of power from USB. If this is what you are trying to do, don't buy this or any similar isolator. If you need an isolator for such a device, make sure it promises to deliver the amount of power you need. Note that these will also be bigger and significantly more expensive. An reasonably priced alternative might be an isolator that features a power supply connection on the device side.However this will work fine with devices that supply their own power and do not run off USB or devices that require little power, such as a USB/serial dongle. This is what I am using it for and it solved a significant noise problem I had with my CNC router.

Absolutely waste of money in my work truck I do not have Bluetooth on my radio I only have AUX so I use a double-ended 3.5 mm headphone cord to go between the radio and phone's headphone jack but when I plug the phone into the charger of the truck whether it be the built-in USB of the truck or the cigarette lighter with USB charging adapter I get buzzing through the speakers just eliminates the buzzing however my phone doesn't charge it does not pass enough power through it to charge my phone I thought it was charging slowly way slower than normal but using this device for about 2 weeks 10 hours a day it didn't seem to be working so I plugged it into a USB to USB power meter and it was only showing maybe a quarter of an amp max output which isn't enough to keep up with the phone ... Go with the 3.5 mm noise canceling adapter it looks similar to this but it's a little smaller rounder and it hooks through the headphone port rather than USB

This device fixed my problem! Had audio noise on a Motorola GR1225 going through a Masters Communications RA-25 USB interface. I tried everything. In-line audio noise filter, eliminating ground loops, extra grounding, etc. Nothing fixed it until I plugged this device in! Amazing! I can see where other people may have an issue with charging phones etc. That is not what it is for so don't complain that it is a bad product. It works!I wish it was cheaper but hey, if it solves a problem, I'll pay the $$$.

Like many of us with complex MIDI studios and computer workstations, noise injected via MIDI connections can be maddening. I was getting significant high frequency noise from my Deepmind 12 when USB MIDI was connected but the noise disappeared when I unplugged the USB cable. This isolation module 100% solved that problem!Keep in mind that the Deepmind is powered by 120V and not via USB. I have *not* tried to power one of my other synths through this device and I suspect (based on other reviews) that it might not work for anything requiring more than a trickle of current. But...this should work great on any device that has the option for powering separate from USB.

No resolvió mi problema de ruido al conectar una interfaz de sonido a una PC. El problema solo se presenta cuando además conecto un subwoofer a la salida de la interfaz de sonido; es posible que funcione para otros escenarios pero lo desconozco.
