KM,Correctly set for reference level, you need to set to 75dB ;-) I think 74 will work just fine!
AVIA is recorded at -20dBFS (20dB below full scale signal) so 85dB with volume at 0.0dB is what you should get. VE is recorded at -30dBFS so 75dB is what you should get. The LFE channel has 10dB extra on it. Both discs account for this and attenuate by 10dB so that the subwoofer ends up at the same level as the other speakers.
Assuming you're using the Radio Shack SPL meter, you should calibrate the subwoofer 2 to 3 dB below the other speakers, as this meter is inaccurate at both frequency exteremes.
Regards,
I use the Ref 30, it's a good pre/pro.
