Warning: newbie question!
I have been stealth taping a stadium rock show and the volume turns out to be way too. I am using an Edirol R-09 and Core Sound LCB mics.
Here are the Edirol settings = AGC: off | Mic Type: stereo | Low cut: off | Mic gain: low | Volume 24
I turned the volume down while recording the first song, because the red light on the Edirol were flashing alot. As mentioned, the recording turns out to be way too low, so I guess that it should flash once in a while while recording? Or not?
The mics were places in front of my chest. I guess I should put them on my collar the next time, because besides the low volume, it sound very ”boomy”.
I hate to stand for three hours again, not being able to clap and sing and hoping that the poeple around me would shut up, so please help me 
What the other people said, plus, I'd add only that those settings seem generally right, but if you do have a problem with clipping (which is different than levels), you may want to consider springing for some kind of power supply for those mics (I'm assuming you bought the LCBs without the optional battery box). I believe Church makes a very inexpensive power supply that pretty much looks like a 9v battery with some gunk stuck to the end. Sound Professionals makes several different power supplies; I use the SPSB-8 which also has optional bass rolloff, which is $69 with rolloff, $60 without I think.
If the volume of the show is too high for the maximum rated sound pressure level of the mics, it won't matter what your meters on your deck say. The power supplies help with this issue, as you can run line-in. I used to run a version of the Coresound LCB way back in the day with a WMD6C analog deck, and (as Len warned me it might) every show clipped. I sent those back, got the "Battery box" version, and everything was fine after that.
And finally, yeah, if you're stealth taping/taping with mics mounted to your person, you can't move, talk or clap no matter where on your body the mics are.
