Hi, I'm looking at the working noise of my Blue Amek Angela (all the channels are muted by the "master mute button on the master channel) and I have this 8K noise equally on both L and R channels.
With the master fader at unity gain the peeks are at -80dbfs and with the master fader all the way down I can still see this 8, 16 and 24 kHz peeks, but under -90dbfs.
Does it a mutter of "dirty mains power"? or modern (and quieter) OP amps will give me a better result?
I've recapped the entire desk 3 years ago.
