Removes USB noise, interference and ground loops for cleaner audio and more stable USB connections.
What is it?
The AAL – USB Audio Isolator is designed to eliminate USB interference and ground loop noise by providing full galvanic isolation between your computer and USB audio device.
- Galvanic isolation of both data and power lines
- Reduces digital noise and USB interference
- Improves perceived background silence and listening comfort
- Helps protect equipment from spikes and electrical disturbances
Result: a cleaner, quieter and more stable USB signal for your DAC or audio interface.
Connectors
- Input: USB-B (HOST)
- Output: USB-A (DEVICE)
Why did you make it?
Many DACs and USB audio interfaces suffer from unwanted interference introduced by computers, USB hubs and power supplies.
Typical symptoms include:
- Digital noise from PCs, USB peripherals, mice or switching power supplies
- Ground loop hum and electrical interference
- Instability caused by noisy USB environments
- Reduced performance with sensitive or entry-level USB DACs
Especially useful with:
- USB-powered DACs
- Laptops running on AC power
- USB hubs and docking stations
- Audio workstations and studio setups
- Home Hi-Fi systems using USB DACs
What makes it special?
Technology used:
- USB galvanic isolation based on the ADuM4160 (Analog Devices)
- High-voltage galvanic USB isolation
- Optimized 4-layer PCB design for signal integrity and reliability
- Independent isolated power domain
Compatible with:
- USB Low-Speed / Full-Speed devices (1.5 / 12 Mbps)
- Many USB DACs and audio interfaces operating in USB Full-Speed mode
- USB HID peripherals
- Windows / macOS / Linux systems
- Driverless operation with supported USB class-compliant devices
Not compatible with native USB High-Speed (480 Mbps) devices.
If unsure about compatibility with your DAC or audio interface, feel free to contact us before ordering.
