idiots guide to the AKG C 3000B please

hello cool cats

the two adjustments on the side of this mic

one is a 0 or -10 dB switch, the other is a (lin) -- sliding upward line graphic

can someone mention when these two settings would be considered in a session?

ps- we did a clarinet ensemble today, four clarinets in a large room with two of these mics
what settings would you folks have had them on??

THANKS

Its basically just a -10db pad for like Montezuma said, blasing your trumpet into the mic. But i would not jump real fast to use that pad. I would 1st lower your gain stages in the chain first to see if that help. If it doesnt and your over driving the Mic itself, then the pad is a great tool to use and you can make up the 10db's with the mic preamp.

I have a C4000b, and it has the same settings. The one switch is a 100hz rolloff. It's nice on low vocal lines that tend to have a lot of bass and muddiness to them. I don't know about that mic compaired to mine, but mine can take a ton of spl without distorting. I doubt you can overdrive it, as I stick mine in an ISO box with a cranked guitar amp and don't have problems. I would probably leave the -10db switch off in 98% of what you do with it. I only use it in loud vocals, or high spl situations. It's nice that it lowers picked-up backround noise, but it lowers definition a ton also if the volume going into the mic isn't loud enough.
