the problem would be a signal that was too healthy overloading the input 
and engaging the limiter. That can also have a low-pass effect. You may 
need to turn the input volume knob down a bit if that is the problem.

I don't remember the exact specs, but the digital path has a pretty 
typical 
flat response that all digital gear has. I believe the passband ripple is 
0/-.2dB. The low-end rolloff point is well below 20hz. Between there and 
19khz it would be flat within 0/-3db. But if you pull in a bit from the 
ends, it would be flat within 0/-.2dB (probably from 20Hz - 16Khz it would 
be flat within 0/-.2dB, but that's a guess because it has been a long time 
since I measured it.)

like Bret said, if you have the gains set up right, you shouldn't hear any 
frequency problems.
