Seeking Help Using REW - Feedback Loop Issue

[Warrior]

During the "Soundcard Calibration" process, I need to adjust my monitor input level to get the input signal level near -12dB. In doing so, I seem to be creating a feedback loop. I have monitoring engaged and am feeding back into the inputs and I am not sure what to do to correct this and still get the right level.

When I set the interface software mixer to mono, it seems to resolve the issue but I have a feeling this is still not correct.

Soundcards etc. are typically flat within less than a dB. I see no need for SoundCard Calibration.

Just following Stuart's instructions in this thread.

Got it figured out, with the help of tech support at Audient.

Great! That looks fine now.

Time to do some tests!

I ran into another snag. I am on step #3 - which is calibrating REW to real sound levels. I've followed the instructions but when I play the pink noise I do not get anywhere near -18dB on the input. Even if I have the volume on my interface cranked.

Am I supposed to see -18dB at this point before adjusting mic preamp and adjusting sound level to 80 dB?

I think I figured it out.
Let's hope so.... just completed my REW measurements.
