Axiom Home Page Forums General Discussion Technical Questions Clarification on calibrating with SPL RS meter?

But if you set the channels up with an exaggerated trim, you will not get the entire AVR volume control as they all have set limits on their range.

Exaggerated trims are beside the point here. If you're running your AVR near the point where this even matters, you need a more powerful amp -- and likely ear protection to boot.

Not with movies. I disagree.

My 7300 and 80's, if calibrated correctly will have an average movie playback of 90 db's at zero and to many, that's normal. It goes to a plus ten. Not a whole lot more, wouldn't you agree?

Now take an AVR will less power and what do you get at Zero?? You do the math.

Stereo is a different story. I can't tollerate the volume much over - 10 on the AVR.

Just another question, when using the Denon microphone and/or my SPL meter, all instructions that I've ever read says to place in the primary listening position for the tests.

I guess my question is that in my scenario I have theater seating, and am not always sitting in one specific location. So what is best in this situation? I've been placing the mic/meter right behind where the middle recliner resides. However, I'm wondering if it would be best to calibrate from the back central location? If I do this though, then the surrounds are closer to that person, which would be different than what the front row people would experience.

Would it be best to pick a location which is the average location for all seating locations?

Randy,
what you should do is pick the seat you like best let everyone know this is daddy's seat. then calibrate to that location. you are the person who will be watching more often then not your guests will still enjoy the movie just as much.

For 2.35 movies I sit in the back row, and for smaller aspect ratios I use the front row.
