The Intona Hi-Speed Isolator is the worldwide 1st fully-integrated device for the galvanic isolation of the USB 2.0 bus in High-Speed mode @ 480 MBits/s.

In a PC - based audio set-up this product is highly interesting of course, when connecting a DAC to the USB bus. Our device fully isolates both data and power lines and is providing a "clean and stable" USB connection eliminating all potential issues such as ground loops and cross currents.

This is a real noticable and hearable enhancement to any system. 80% of our applications are so far in audio systems (20% industrial) and we have an overwhelming customer reaction when they are using our device for the 1st time.

The device is a simple plug and play solution, no drivers or installation needed, basically it behaves like a cable.In addition the device is developped, engineered and manufactured in Germany.

The Innovation

Previous isolators where limited to Full Speed (12 MBit/s) and Low Speed (1.5 MBit/s) transmission. This new product is capable of transmitting USB Hi-Speed (480 MBit/s) while providing full galvanic isolation of both the data and the power lines.

USB 2.0 Hi-Speed Isolator withstands up to 2.5kVRMS

This product is an ideal solution to break ground loops, avoid noise coupling and protect ports from power surges and voltage spikes in applications which require high speed USB transfers. The galvanic isolation barrier withstands potential difference up to 2500VRMS.
