But is seems I have to cal. my RS SPL meter, then do the soundcard, but I guess then I have to have the whole system up and running. Hope this makes sense.
Yeah OK, I get what you were referring to.

First you calibrate the soundcard as you did, but after that you need to run the Check Levels routine in the Settings popup. It will create a subwoofer signal, and you need to turn up your receiver until your own SPL meter reads 75dB at the listening position. Then you set the Input Level to finish the Check Levels routine.

Once you've done that, you have to tell REW that its own SPL meter is reading 75dB. How would it know otherwise. To do this you press the CALIBRATE SPL in the Settings popup under the Meter tab.

Then you can Measure.
