Hardware Tip from Elektor: USB Isolator
Avoid interference and earth loops
Maybe. But isolation is built-in on the Ensembles. (Provided the constructor keeps it that way).
And a similar system might be incorporated in earlier models when adding a Si570.
62 UKP is a lot for a transformer and one or two optoisolators.
