1. Set it to C-Weighing
2. 70db on the dial
3. Sat in my main LP and placed it on my thigh (best I could do)
4. Started my test tones on my Yamaha AVR
5. Turned my Volume to 0 db
6. Adjusted all my speakers till it read 75 db on the meter.

Completely different from what YPAO had set it, especially the Sub. I am going to try again mounting the SPL meter to a tripod of some sort and see if I get a difference. I did have a 1-2 db difference when I held the meter straight up as opposed to pointed towards the front.

One of the best 50 bucks Ive spent.

Yes it can be great but you do want it at ear level as that will affect the readings as you know.

I know. I am going to try that again when the family is out of the house.

Would someone mind posting the advantages of the Galaxy meter versus the Radio shack?
I am just curious if it would be worth it to have a Galaxy shipped to me, versus just stopping by a local RS to pick up one of their meters.

Radio shack doesn't sell the analog anymore.

I am considering this, just not sure what to DO with it since I am so new to this:
http://www.amazon.com/gp/product/B00...=A9DVUS2B9UXTW

But I read a lot of arguments about going the other way entirely and using something like:

Dayton Audio EMM-6 Electret Measurement Microphone

I wish I knew what the heck to do and then, HOW to do it. I have already downloaded TRuRTA and REW. Both make me more dizzy than usual just opening the programs and wondering what to do...

If you're just using it for REW, get a UMIK or a UMM-6. Both are USB microphones that plug in directly to your laptop and can be calibrated with their file through REW. I use a Dayton UMM-6 for all my measurement needs.

You don't want to take measurements with a C-weighted meter; as CW is -6db@20hz and -3db@7khz


A UMIK-1 with calibration file is typically 5-25khz +-3db; and since it is USB it doesn't need a soundcard or mic-pre with phantom supply.

It's best to have both, one to tell you the approximate SPL as a portable handheld device and the other to tune systems with in detail.

Yeah the Dayton UMM-6 is what I want, even though I then need anothjer $12.00 adapter cable from the mic to my PC. I have no idea what exactly I will end up doing with any of it. I'm disabled/retired so have 24/7 to try to learn and maybe make a new hobby playing around. have ALL brand new A/V equipment just in the past 7 days so ready to learn something darn it. Seems to me there are vastly more doors I can open up owning the Dayton UMM-6 than an SPL? I mean, my iPad has a free program I used to "tune" my 5.2 system minus my 2 subs. I'm just toying around but desperate to have something to LEARN to quit thinking about the [physical pain I am in. I actually more shocked my wife hasn't shot me and done me more damage than the 4 bullet & shrapnel wounds have done when I bought all this last week.

This hobby is not just a hobby. I have discovered that good A/V can take you both to and FROM places you need to be or leave. It is a journey, a love affair, a passion. I am smitten, in love am hooked. Kinda tell that even with the lowly equipment I just got (have a very tiny budget), I am still walking in the clouds with excitement. Imagine if I ever got REAL "stuff"...Thank God for this forum who led to to where I am now at least.

Thank you BassThatHz. I wondered about that but my total ignorance makes me afraid to make any assumptions anymore. It also makes me wish I had a faster wheelchair that could outrun my wife....
