Topic: UFX trs analog ins have random noise floor issues
I've had my UFX for a few months but lately I've noticed an issue on the 8 analog line ins where the noise floor on all 8 will suddenly jump up from around -100 to -70ish, up and down randomly for minutes at a time. Nothing is plugged into these lines so it's a little worrying why it is doing this.
I've been able to record a sample if that helps.

44.1khz-16bit mono - normalized +72dB
This is just a recording off Analog 1, but the same problem is replicated across all line in channels (not the mic channels).
From that recording under a spectrum analyser you can see it's mostly a huge sub-bass thing going on.
Is something wrong with my unit?
Anyway I can fix it? (prefereably without having to send the unit somewhere, a firmware update or whatnot)
thanks
