  • Description

This product is an ideal solution to break ground loops, avoid noise coupling and protect ports from power surges and voltage spikes in applications.

The High-Speed isolator is a crucial component in audio setups, providing galvanic isolation between the USB host and device while offering protection from power shocks and preventing ground loops. Here's an overview of its features and benefits:

  1. Galvanic Isolation: The isolator ensures galvanic isolation between the USB host and device, preventing electrical currents from flowing between them. This isolation helps eliminate ground loops and reduces the risk of noise and interference in audio signals.

  2. Protection from Power Shocks: It protects the connected device from power shocks, ensuring its safety and longevity, particularly in environments where power fluctuations or surges may occur.

  3. Support for USB Transfer Modes: The isolator supports USB transfer modes including Low (1.5Mbps), Full (12Mbps), and Hi-speed (480Mbps). This versatility ensures compatibility with a wide range of USB devices, including those requiring higher data transfer rates.

  4. Enhanced Power Delivery: With a power output of 400mA to the connected device, the isolator provides more power compared to standard USB isolators (typically 200mA). This increased power delivery is beneficial for powering devices with higher power requirements, ensuring optimal performance.

  5. Compatibility with DACs: The isolator supports Hi-Speed 480Mbps, which is required by DACs (Digital-to-Analog Converters) that support sample rates higher than 96kHz/24bit and multi-channel DACs. This compatibility ensures seamless integration with high-quality audio devices.

  6. Optimized for Audio Applications: Designed specifically for audio applications, the isolator addresses common challenges such as ground loops and electrical interference, ensuring clean and reliable audio signal transmission.

  7. USB SuperSpeed Compatibility: While the isolator does not support USB SuperSpeed 5Gbps, this mode is rarely used in audio devices. Therefore, the isolator's focus on providing Hi-Speed 480Mbps is well-suited for most audio applications.

Overall, the High-Speed isolator offers essential features and capabilities to meet the demands of professional audio environments, providing reliable galvanic isolation, power delivery, and compatibility with a wide range of USB audio devices.


  • Supports 1.1, 2.0, 3.0, 3.1 USB ports

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

  1. The 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.

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.
