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.
Supports 1.1, 2.0, 3.0, 3.1 USB ports
Supports Low (1.5Mbps), Full (12Mbps) and Hi-speed (480Mbps) mode by automatic detection
Supports audio and other devices including high resolution 384kHz and DSD DACs, USB midi devices, USB mixers, USB microphones
Provides 400mA to connected USB device
No driver required, no settings to configure
Self powered, no external power needed
Signal isolation: 3000V
Voltage isolation: 1000V
Voltage Isolation 1kV
Size: 55x35mm + cable 10cm
What is the difference from the cheaper USB isolator?
There are two main differences:
The new High-Speed isolator supports USB Hi-Speed 480Mbps mode, required by many audio devices.
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.
