Thanks for the response John. If I mute all outputs except WAVE I get "Unable to detect feedback loop....." so I left things alone (only thing muted is direct monitor)
I was able to play around with things again and turned the input knob down to about 1/4 volume, this gave me a good looking soundcard calibration result that I was able to repeat (and matched my results from 2days ago). See below:
I then went back and ran "set input volume" to see where the responses was, and as you can see it's off the charts low. I only get peaks in the mid -30dBs.
I left things alone and then proceeded to set the SPL meter. I can adjust the level on my processor and REW follows accordingly, will I have problems if the input volume is low as noted above?
I ran an automatic measurement on channel left, as directed by the setup guide, and came upwith this. Any reason why the responses are at the levels they are (soundcard cal now at ~85dB and measured at ~95dB?)
It looks like I'm getting some sort of improvement here, but not sure - could be all screwed up! Thanks again.
