OK, so I think I figured my problem out with brickwalling my Korg using my MKH 8040's.
http://taperssection.com/index.php/topic,119072.0.htmlBasically, at 120 db, with an efficiency of 20 mv/Pa, the 8040's put out about -6 dBu, which can easily stomp the pre's on my MR1000 (max input -16 dBu). Now, since I can still hear, I'm guessing the actual sound was something south of 120 db, but even so, clipping's certainly possible.
Interestingly, the 20 mV/Pa is the same sensitivity given for my AKG 481's, and I've paired them with the Korg in the past without problem.
One question I have - those measurements are done at a reference frequency, such as 1khz, correct? That being said, if the MKH's are more sensitive to low frequencies, those low frequencies would result in higher energy levels all else being equal, correct/ So it could be the MKH's low end sensitivtiy that's driving the energy levels too high and clipping, correct?
The reason I ask is because I'd rather use a high pass filter (which I hear is on the way) rather than a -10 db pad, which is what I'm using now...
Thanks!
