The use of an isolation transformer is SOP when doing this kind of thing. I typically use one of these to isolate FOH from Videotown for our record and monitoring feeds.

This one seems fancier with some ground lift switches but the ground is isolated by the transformer so I'm not sure exactly what you're paying for, maybe the ground is causing noise upstream of the transformer and this helps prevent it.
