Actually, were not too far out of agreement Mikec. I also re-calibrate my levels whenever I change cables, components, speaker placement, or whatever else may have affected my settings. What I meant in my previous post is that with my digital meter when the initial signal is generated. the meter takes a second or two to "settle in" (for lack of a better term) to the actual reading being observed. An analog meter will shoot the needle actually faster to the setting than my digital meter takes to proccess then display the result! This is why I only use sustained test tones, I can run each tone for minutes as opposed to the few seconds each that my processor outputs (it has no manual setting). I hope that clears up any confusion on my original post. As far as sound pressure levels bouncing off my body, thats a good point, but the way I look at it my body's going to be there every time I'm listening anyway! (joke intended!) Anyway, for the 35 bucks or so for these meters you cant really go wrong when compared to calibrating by ear! Later...
