AUDIOPHONICS USB Isolator Module ADUM 4160 Raspberry Pi

As its name suggests, an isolator can electrically isolate the data and / or power lines from a USB connector.
Theaim is to remove any electrical connection between the input and the output in order to avoid maximum electrical and electrostatic disturbances to interfere with the audio data.
The power supply available from a usb connector is very noisy and filtered as drastically, it is not surprising to find traces of audible parasites in the final render.
And it's even worse with laptops!

Another problem regulated by this isolator is the appearance of loops of masses when connecting modules by usb.
You are not unaware of the impact these loops have on the audiovisual material ... The fewer the better, the better.
heprotects also your fixtures / fittings overvoltages,electrostatic discharges and other rises of powers likely to happen when the computer malfunctions (or in stormy weather ...).

This module is intended to be placed between the computer and the self-powered device to be isolated.
