Hi Shaun,

It's really hard to tell from this and I'm not expert on LAN isolators. The penultimate bullet re AC hum I think refers to breaking potential 'ground loops' where the ground on one piece of kit is at a higher voltage than another and 50Hz currents flow. That's the low 50Htz hum you sometimes hear on a system.

Surge protection is a great thing of course, so that's good.

I still can't see any reference to selective filtering of higher frequency noise - i.e. stuff sitting at a higher frequency than the wanted range of signal frequencies, but it's entirely possible that it's there anyway.

I'm with you on trying it out. It could turn out to be every bit as good as the GISO and we'll build up a good head of knowledge between on this thread.

I'd be very interested to hear how you get on.

Cheers
Dave
