Did you try it with a basic power strip to see if it did the same thing as the Furman?
For real, to get real 'power conditioning' you need way more hardware than what a "cheap" furman can provide. You better ratchet your cash up in the the upper 3 digits even to begin shopping, Otherwise you're not getting anything than a decent strip in a fancy box.
My first test is a basic outlet tester that I carry in my gigbag to make sure everything is wired correctly. If it ain't, you can't fix it and you just might get killed if multiple outlets are wired wrongly or just not the same.
yes, before i went on the other side of the building i plugged into 2 strips with same results.
I own several circuit analyzers ("basic outlet tester"). I am an electrician. I got the fixing and troubleshooting down.
