I was under the assumption that turning up the master to 75db tells you where the reference point is at, and then turn up each speaker using the individual levels at that same master volume determined by the front left speaker. SO, my front left is going to be 0 no matter what because that is adjusted using the master....correct? Then the others are adjusted using the individual volumes from -12 to +12 db... But, since I have the master cranked up to reach 75 db, the other speakers are really only being adjusted by about + or - 1 or 2 db....am I thinking incorrectly?

You set the front left to 0, play the front left test tone while increasing the master volume until your meter reaches 75dB. Then as you cycle through the other tones you adjust the speakers individually so that each of those test tones registers at 75dB. At this point, whatever master volume setting you were at is the reference level.

So, your front left will be at 0, correct. The others may require more than a +/-2 dB change though because they may be further from the sweet spot, angled differently, or have some odd reflecting properties due to things in the room.
