v2.0 available now! We made some changes to support more DACs, as some DACs didn't work with v1.

The High-Speed isolator provides galvanic isolation between the USB host and device and protects the device from power shocks and avoid ground loops that can be very troublesome in audio. Our original Hifimediy USB Isolator has been very popular since it was launched in 2013, but the drawback is that it doesn’t work with all USB devices. The new High-Speed Isolator works with many more devices and provides a long awaited solution to ground loop noises for users of sound cards like Focusrite, Steinberg and many more.

If you have tried our USB isolator in the past and found it wasn’t compatible with your equipment, then there is a very good chance that the new High-Speed isolator will work. It supports all USB transfer modes, Low (1.5Mbps), Full (12Mbps) and Hi-speed (480Mbps). Hi-Speed 480Mbps are required by DACs that support higher than 96kHz/24bit sample rates, and also multi channel DACs.
The new isolator also provides more power, 400mA to the connected device, vs 200mA from the other USB isolator.

FAQ

What is the difference from the cheaper USB isolator?
There are two main differences:

  1. The new High-Speed isolator supports USB Hi-Speed 480Mbps mode, required by many audio devices.
  2. it can provide double the power to your device (400mA vs 200mA).

Do I need the High-Speed isolator, or can I use the other cheaper one?
If you have a two channel DAC that supports not more than 96kHz/24bit then the non High-Speed one is likely to work if it doesn’t require too much power. If it has mic preamp, phantom power or is a bigger type sound card then it might to require more than 200mA power and the High-Speed isolator is required. 

Will the High-Speed isolator work with my audio or other USB device?
It probably will. 

Does it require a driver or special setting?
No. Similar to a USB hub, the isolator is “transparent” to the computer and doesn’t require any driver or configuration in settings.

Does it support USB 3.0 and 3.1?
Yes it works with USB 3.X ports. It will max out at 480Mbps, meaning if you connect a USB3.0 hard drive you will not get transfers at 5Gbps speeds. Audio devices doesn't need more than 480Mbps, so it will be sufficient. Most devices that require USB galvanic isolation doesn’t require 5gbps.

Does it support asynchronous USB?
Yes it supports all USB types, the isolator doesn’t care, it just passed on the data to your computer. 

Will it improve the sound quality from my DAC?
It depends. If you are experiencing noise problems, then it will probably remove or reduce those if they are caused by a ground loop. The noise could also be caused by other factors, like the microphone or preamp itself (some gear are noisy!), the isolator will not help with that. It can also clear up the sound from ground issues that is not so apparent, creating a clearer background in the audio. If your computer has a good quality USB DC supply then the isolator might not further improve the sound quality. You’re welcome to give it a try and send it back for a full refund if it doesn’t help with your unique situation. You can also contact us if in doubt.

Will it fix the noise I’m getting from my sound card/microphone/midi keyboard/other device?
It will fix noises that are caused by ground loops, often presented as whining, buzz or loud shh noises. As long as the problem is not caused by the microphones/preamps itself (some microphones are noisy!) then it’s very likely to fix the problem. You’re welcome to give it a try and send it back for a full refund if it doesn’t help with your unique situation.

I bought the full speed isolator which works perfectly when just playing back music but is too slow for multi track recording. I decided to buy this high speed isolator with a much higher transfer rate but it did not work at all with M Audio Fast Track Pro on a widows 10 computer. Windows flagged up a warning message:USB device not recognised. The last USB device connected to this computer malfunctioned and windows does not recognise it. They asked me to send the unit back and they would send me a new unit - that was six weeks ago and they have stopped replying to my emails. So they have £70 of my money and I have nothing. HIFIME REPLY: We are VERY sorry that you didn't get any reply in time. We have refunded your payment in full now. (duplicate reviews merged).

Noise through my sensitive headphones is gone. Before I could hear mouse and network, now it's dead silent. Not to mention an increase in overall detail. A definitely must have!

Finally the buzzing has stopped! Before I would get an increasingly noisy buzz that correlated with the load on my system that slowly drove me insane. Now my audio is crystal clear again, thanks!

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!
