Just recently took delivery of a used Profiler Stage, and while everything sounds great there's a noise issue I can't seem to resolve. It seems to be coming from the unit itself, as it's present regardless of what guitar, guitar cable, power cable, or location in my house I use. It's present in every output from the unit (headphones, XLR, etc.), and does not respond to any of the output control settings. It's louder in gainier profiles, or when increasing the gain on a given profile, but still present in cleaner ones as well. I've linked to a recording here:
The unit has been updated to the most recent OS. For what it's worth - using the same guitars cables, power cords, etc. with my other gear (amps, direct box into my interface, Line 6 Helix) in the same room does not yield the same issue. Any guidance would be greatly appreciated!
