Ran across this video- anyone care to weight in on this?
https://www.youtube.com/watch?v=JpGAi4az3ns
He uses a signal generator and views a 400Hz on oscilloscope- it shows signal at 1.2V RMS which he says is equal to +4dBu (pro audio line level)
He splits the signal and runs it into a computer using a Behringer 302USB then shows how Reaper indicates signal as -15dBu.
I posted the following on the Youtube video:
"Very interesting, thanks. Would be interesting to see if that Behringer 302USB (I have one) or the split are affecting things at all. I do not have a tone generator or scope here at home or I would try to duplicate your findings. I am a Reaper user as well.
Questions:
1- audio is entering Reaper through the Behringer 302USB digital (USB) interface to the computer, yes?
2- Can you somehow test the analog output of the Behringer using the scope pre-Reaper?
3- Can you somehow test the signal on the scope after the split?
I could go on but basically you can see I am trying to rule out possible variables that could be affecting the results.
Thanks!
