This is my first post here. It's a generic audio question, but since it involves recording gear this seemed a good place to ask.
I had been routing my computer audio output vis USB to a Radial USB Pro to my Hafler P3100. With no playback, the lights on the P3100 indicated idle. I also have a Focusrite Scarlett 2i4 that I use for audio input. I recently realized it will do output from USB as well. Looking to simplify my hardware setup, I ran my computer audio output vis USB to the 4i4 to my P3100. With this setup the P3100 lights shows -40db output (two lights on). I can't hear any hiss on the speakers unless If I max the 2i4, it goes to -30db, but I still don't hear any hiss. Is this normal? Am I worrying about nothing?
The only input to the USB Pro is USB from the computer while the 2i4 has analog audio inputs as well (a Roland RD 2000 in my case) so the analog audio might have something to do with it. I'm only guessing. I can always go back to the USB Pro. I'm mainly asking just to better understand what to expect in the way of sound levels.
P.S. When I turn off the Roland RD 2000, I get a noticeable hiss on the on the speakers, but that's a separate issue.
