I normally use a Mackie 3204, so there is no way to "accidentally" plug something into a mic level input. For those of you not familiar with the 3204, it provides 2 mic pre-amps with XLR ins and 1/4" outs. And then you have to patch the outs into the mixer itself. Actually a very cool setup because the preamps do not have to go directly into the mixer at all. This was actually just a thought. I got into a debate with a friend a couple of days ago. Good info! Anxiously waiting for my MOTM one-size-fits-all mixer. Cheers! Todd > -> >You probably would not damage anything EXCEPT if you had > -> some speakers > -> >attached.
