I need help connecting CSB's to a Church 9100. The CSB's come with their own battery box, and mine happens to be the one with the with the rolloff switch. The battery box on the CSB's connect via 4 pin mini-XLR in the middle of the mic cable, and the setup ultimately terminates at a 1/8" plug. My goal? Get rid of the CSB battery box.
Based on a post from Chris, the 9100 provides plug in power that is total Volts minus 1. So, I assume with a fresh battery in the 9100...one would get 8V of plug in power?
http://taperssection.com/index.php?topic=79928.msg1422531#msg1422531In an email I got when I asked Len from Core Sound about this he states:
"Sorry to say that it's unlikely that the Church Audio pre-amp can supply the -9 Volts and correct current limiting resistor that the CSBs require, so you'll still need the battery box."
"As I mentioned, the CSBs require -9 Volts."
These are from two different emails, so what's with the -9V? Is that "negative sign" of significance? Sorry, if that is a dumb question...I would just expect it to be positive.
Initially, I had hoped that I could just jump a few pins on that CSB battery box connector (middle of the mic cable) and get the plug in power from the 9100. Apparently, it's not that simple.
If I have to carry around another 9V battery just to power the CSB's, at least I'm hoping to build something smaller than the Core-Sound box (Heat shrinked parts and naked 9V, no rolloff feature necessary). So, I seen several DIY schematics for battery boxes...can anyone suggest a favorite?
Is there another way to get rid of the Core Sound Batt box without going through all the hassle? Before anyone says, "buy different mics"...I'm trying to be economical.
Best Regards and thanks for any advice you can share!
