Hi everyone, okay so this is a fairly complicated problem but I'll do my best to explain it clearly.
I use my Apogee Ensemble Thunderbolt to record DI's as well as run the thru output to the axe-fx for amped tone, then later I reamp it through the built in box on the apogee to the axe. This system was working really well for me until last week when a ringing popped up.
The ringing (hear samples below) is only at 3000z and 6000hz and can be removed with a EQ at those exact frequencies.
The ringing occurs only when using the guitar Output from the apogee, never when I plug directly into the axe
The ringing occurs even when I'm plugged into a different amp (say my sans amp for bass). Even when the only cable to the axe is the power.
The ringing only occurs when the axe-fx is on.
This problem seemed to appear from nowhere, no new gear or re wiring.
The axe-fx and the apogee are in completely separate racks.
The apogee and the axe-fx do run from the same power conditioner.
The ringing stops when they are in different outlets.
The ringing isn't affected by any other gear I have running, or by A/C, refrigerator or any other electrical things in the house.
Ring Sample(axe-fx on, through sans amp):

Without axe on (same setup):

All of this leads me to believe that it has something to do with the axe-fx power supply, or maybe how it reacts with he apogee. Any help would be greatly appreciated.
I guess the simple answer is to have the axe on it's own power but I'd really like to keep everything neat and tidy with one switch. And also I'm curious as to why this happens.
I live in the U.S. so 120v, 60hz power.
Thanks,
Adam
