Well, I got the battery in then got stopped at the first step. What does it mean "Range"? Decibels, hertz, home on, WTH? That was step #2-set the "Range". I have no clue about how to use the thing. What I'd like is a print-out of a scale from 20 to 20k hz and a test cd that has recorded bands about 20 hz apart with an announcement of the number before each. Is that too much to ask? I'll use the "C" weighting unless there is some reason not to.

Hit the Rives audio link on the main AA page. They make a CD with a set of tracks like you described that matches the response curve of the RS meter.
. . . identifying LF room modes, and dialing in a subwoofer, in conjunction with a disc of test tones. Totally untrustworthy at higher frequencies: there is typically a response peak around 6kHz, anywhere from 6 to 18dB, and NO unit-to-unit consistency.
For the purpose of measuring bass SPLs in-room:
Set the meter up on a tripod or other stand at your usual listening position. The meter should be about where your head usually is.
Set "weighting" for "C" to capture the broadest frequency range, and set "response" for "fast."
With pink noise or a 200Hz test tone playing at a reasonable (for you) level, set the dB "range" to where the display reads in the middle of the selected range, and doesn't read "over" or "under." Once you establish a reference level (say 85dB), you can then read the relative levels of different bass frequencies and jot them down and chart them. This gives you a starting point to think about EQ or room treatment.
The instructions that came with mine certainly implied that use at higher frequencies was not recommended.
I hope some day one of the reviewers can check out and advise us how accurate these are and suggested methods for using them to analyze components and the room.
I like to take the meter to dealers when shopping. Like when i checked out the Maggie 3.6 i now own. i made certain the speakers SPL was what I listen to at home by placing the meter right at my ear level. So then I get a little better idea of the sound as compared to home. My dealer sort of liked the sound level he was hearing during my audition, and asked me what it was.
I find dealers nearly always crank the sound level way too high for my taste. I like 70dB to 80dB.. They seem to start out at least at 90/93dB
Right now my earphones (it's 5AM) are at 72dB 1 inch from earphone speaker surface.
Also, when the cops come because your neighbors are complaining.. you can point out the sound pressure level is well withing legal limits.. etc.

I'm talking about a Radio Shack spl meter. Sorry about letting my frustration get in the way . Sound pressure level meter.

Thank you, Mike.
It's in the Faqs!
You got me lost in respect to, what the heck did you just buy, and what the problem is.
Can you provide us some link to device you got, or at least it's model number?
