Question about "reference" calibration.


I have been messing around with REW the past few weeks.

Something is not clear to me is with regards to what I call my "reference" calibration point.

When I use a SPL meter and go thru my receivers test tones...I start with everything set to 0 then increase the AVR master volume until the SPL read ~75db for the front LET channel...then I adjust all the other channels to match. For me that comes out to a master volume of -20.0 (on the AVR display). So when watching movies I set the AVR master volume to -20.0..which I always assumed meant I was at "reference".

Yet when I do the check levels and such with REW...My master volume ends up around -34.0(on the AVR display) which shows 75db on the SPL meter.

Is this normal?

I ask because when I am finally done with all this and have done whatever EQing i end up doing...I would like to go back and make sure all 5 of my speakers and my SUB are matched...just not sure if I should not use the AVR's test tones anymore.
