Just got an ATEM Mini Pro ISO.
It's making a humming or buzzing sound, which starts immediately when I power it up, with no cables attached except the power adapter.
It's on my desk, about 2.5-3 feet away from my head.
Holding it up to my ear, the sound seems a little louder from the right side, which makes me wonder if it might be from a transformer, since the power adapter attaches on that side. (It doesn't sound to me like fan noise, but I'm no electronics expert.)
I'm wondering if this is normal. In a room with a lot of ambient noise (a church, school, etc), it might not be noticeable. But I have sensitive ears and my room is fairly quiet.
I made this recording by holding the bottom edge of my iPhone 6s up to the rightnside vent:

They didn't answer the question, which is exasperating - this isn't rocket science.
Instead, they offered to look at the unit if I sent it to them at my expense. That would be OK if it were out of warranty (or nearly so, but heavily used). But this is brand new.
Either the sound is normal or it's not. (And if I have a DOA unit, returning or exchanging through B&H would be faster and easier.)
Anybody else hear this sound from their ATEM Mini (any version)?
Thanks!
Bob
