DSD TECH SH-G01L USB Isolator Supports USB 2.0 480Mbps High Speed Isolation

This is a great USB isolator. I have a Focusrite Scarlett 18i20 1st Gen. It connects to my computer with a noisy Nvidia GeForce RTX 3070 Ti. When I'm playing games, I can hear the horrible electrical interference any time I have any outputs (namely the monitor outputs that I'm using) on the 18i20 connected to my Ashly LX-308B (a stereo, balanced line level mixer) that I use for listening to my PC, Xbox, and monitoring the audio interface. Therefore, I'd have to disconnect my audio interface's audio outputs when I played PC games, so I wasn't even given the choice to be able to monitor anything on the 18i20. I'd have to use another DAC to listen to the games. This wasn't a dealbreaker but was very annoying. Enter this isolator. It just plugs in, needs no extra power, and eliminates all of the noise. It's essential and works without any issues. It's also the cheapest option out there, so I'm very happy with it. If you're trying to do software defined radio USB, do not get this. The isolator chip in it will not perform well for radio. For 99% of users, you won't care about that (I didn't even know it was a thing until I saw a bad review on this), and you will have no issues with it. The 400 mA may not be enough for the hungriest of devices, but you can use this with a USB hub so that your device can get galvanic isolation from the PC but still get the data. I've never had noise issues from USB-IF compliant USB 2.0 hubs. I can confirm that it's a nonissue for the AC powered 18i20, though. 400 mA is already way more than what the competitors offer for more money. You do not need the 100-dollar ones that claim 32-bit 768 kHz. Just get this.

I have a DAW home recording studio with multiple components that have been recently purchased and was having noise issues on the monitor speakers. I'm using a Focusrite Scarlett 18i20 DAC, Presonus Faderport 16 controller, Sansui 27 inch WQHD monitor and a GMKtec mini computer. Noise was audible and fluctuated when using the mouse and keyboard navigating on the computer. This is generally a "ground loop" issue especially since my audio monitor cables are balanced. If you are experiencing a noise that is monotone it may be simply a faulty cord or power adapter and not a ground loop. Unplug each component one at a time to isolated the noise source. The ground wires in your home do not carry active house current and is a secondary protection in case of electrical shortages that will allow current back to the panel to trip a circuit breaker instead of a person being in series with a circuit in the event of an electrical anomaly. However unwanted magnetic fields with a wire nearby (such as a ground wire) produces signal currents that may interfere with devices sharing a circuit. Fan motors such as on computers may generate magnetic noise in this fashion. On my system when plugging and unplugging the USB cord from computer to DAC, noise would follow accordingly. After installing the DSD TECH USB isolator at 480MBS it worked like a charm and eliminated GL noise. I like the mini length cord since it allows room to plug in at the device with tight spaces sharing USB ports unlike the other more expensive bulky non-corded isolators. Also its reasonably priced comparatively and does NOT need a secondary power source to operate. I do not usually review products but wanted to post my experience to help anyone who has audio equipment noise issues and has been perplexed to find a solution. I highly recommend this product for ground loop issues for USB 2.0!!

Does the job. Quieted my Katana amp down. The USB connection was constantly buzzing and this isolator did the trick. Very quiet...

This isolator works very well! It took my audio from a computer (USB > audio out) that was almost unlistenable due to random hiss/squeals/whining noises to complete silence...well, except for the music I wanted to hear ;-) For me, it was well worth it!

This solved the grounding issue between my PC and CNC plasma table that kept the torch from firing.

I have a Silkland USB-C connection coming from a Dell XPS-15 to a Plugable dock, then into an AudioQuest Cinnamon USB-A to a Centrance M-8 v2 DAC. From there it goes balanced out to powered Yamaha speakers with a sub. It's all dead silent until you connect the laptop with the Nvidia card in use and the crackling whine was extremely irritating. That's close to $3,000 worth of audio gear and cables, excluding the laptop. I've had to go to town to get rid of all the noise that was being picked up and there was one thing left and this filter solved it. I was hoping that this filter would do the job and I'm thrilled with the outcome. The noise floor on the DAC is less than -100 dbm and so all I'm hearing now is dead silence, exactly what I expect. Like others here with DAC noise issues, this will at least solve it if you place it in the correct spot in your device chain.

I've now tried several well-known various Hi-Fi brands of USB conditioners/denoiser devices over the past few years. Most have worked (from what I could tell). And in some cases, you really couldn't tell much of a difference. So I gave this DSD TECH SH-G01L Isolator a try, and yes, I could certainly tell a difference - but unfortunately, it was not for the better. Once connected (I purchased two of these), I assumed everything would be okay - but then my USB based DAC and digital decoder units would begin dropping in and out (sound-wise). In other words, when they dropped out and the music stopped, I checked my equipment list in Windows Device Manager, and wallaaaaa - they were not listed at all. Then magically, within a few seconds, the units would come back online again. And this process continued. At first, I had assumed that I did not connect the units properly, but all seemed fine. The moment I disconnected my DSD units from the various USB inputs, the sound returned to normal. No go figure? In the past when I used similar devices from iFi or Audioquest (and a few other well known brands), I never had these issues (dropping in and out), and they functioned superbly with improved sound characteristics. But these DSD units were a total bust, I'm afraid to say. So these units came as a total disappointment and for those folks looking for a better "mouse trap," I'd say to save your money and look elsewhere. Totally unsatisfied here.

I purchased this because my GPU was giving me feedback through my studio monitors while under load. I tried balanced TRS cables. Ferrite filters. Rewiring. Everything. This product solved the problem completely. If you use an audio interface that plugs in via USB, this will 100% fix any hardware feedback that generates through your speakers. It was an annoying buzzing noise, and now I have blissful, clean audio with no background buzz. The product itself has a snug USB port, so I am confident the cable wont ever work its way out on its own. Overall quality is fantastic. Could not be happier!!!

Great product, works great. Used it to eliminate a high pitched noise in my HX Stomp guitar pedal. It always whined terribly in the audio path when connected to USB in my setup; dead silent now with USB connected. Very happy with this.

Get rid of the noise created by a groundloop completely, without breaking the bank compared to other solutions.

Works well with sound cards.Is not ok for DJ controller.Crash Serato all the time. Otherwise is great devices.

Using it to deal with ground loop noise on a Korg Minilogue USB connection. Eliminates noise completely.

Jeżeli trafileś tutaj bo twoje monitory studyjne (KRK) na twoim interfejsie (Focusite scarllet solo 4 gen) - buczą albo trzeszczą, szczególnie przy ruchach myszki, albo przy wlączeniu gry - to masz ten sam problem co ja - klasyczna pętla masy :( Ale dobra informacja to ta - że to urzedzenie go rozwiazalo w 100 %!! Problem rozwiązany :-) POLECAM, nie pożałujesz !!!
