As Macrojack said, there will be a time delay for the A2D, compensation/EQ, and then D2A processes. I differ from Macro in that I feel the delay will be audible at least as a discontinuity, especially at 200Hz. If you were just doing a subwoofer below, say 80Hz, then the delay might not be noticable, but there's just too much going on at 200Hz.
