Hello- I have decided to forgo my YPAO on my Yamaha receiver and see what the results are using the Radio Shack analog SPL meter. Is this redundant or do you feel it is more accurate than YPAO?

More importantly do many of you find there are channels that consistently need to be bumped up from what the SPL meter indicates?

Thanks!!

It is more accurate once you get out of the sub and low bass ranges. You need to figure in some fudging with low freqs. There's an excel worksheet that takes your raw RS SPL figures and turns them into real numbers for those ranges.

The only thing I had to boost higher was one of my surrounds. Don't know why, but it felt like it wasn't giving the umph at the SPL calibrated levels.

Joe is right, here is a website that has the RS SPL meter "fudge factor" factored in. Scroll down and there should be a link to the spreadsheet.
