I dont know about sound professionals, but if you choose church audio, you wont be dissapointed for sure. If you want, I can send you some samples from some live shows. I recorded some lately.
If you have recorded some loud rock gigs, please send me some short samples to webmaster [at] queenconcerts.com
Also I see you have the CA-9100 Preamp - is it an important thing to have or would a $30 battery box do basically the same job? I suppose I must read the forum a bit more to get these answers... ;-)
You didn't ask me anything, sorry for answering
. I'm not an expert, but I do know this one.
We're talking about two different things here. A battery box will power your mics, so you don't have to use your recorder's plug in power. The bb will provide your mics the needed power to handle higher SLP ( in other words: loud rock gigs).
A preamp also powers your mics, but it's main purpose is to amplify the signal coming from your mics towards the the Line input of your recorder. In a loud rock gig you can use only a battery box. But you can do like many folks around here ( myself included): low rec level ( recorder) and use the preamp ( usually) cleaner gain.
Hope that helps
