I own three of these attenuators and they're pretty much life savers! There is a very serious design flaw on the M-Audio ProjectMix. The console has a phantom power switch which applies to all 8 preamps when activated. In order to record acoustic drums it's necessary to use both condenser and dynamic mics. However, since the console doesn't have attenuation pads on it, the signal on the dynamic mics for snare and kick drum gets boosted way too high, clipping even at minimum gain settings on those channels on the console. This is where these attenuators come into play. By using them with the snare and kick drum mics, I'm able to tame the signal by -30db, -20db or -10 db to taste with a 3 position switch. I have a third one just in case I need to tame a tom, depending on the song I'm recording and the drummer setup. I'll get two or three more of these babies soon. Very useful!
