RE: Biamp / triamp MGIIIA...?

In a typical passive XO, the phase shifts across the frequency spectrum, usually 180deg from 20Hz to 20kHz. This is due to the passive components in the circuit not responding in time alignment as the frequency increases. Active XO's and parametric EQ's act similarly because the passive components used in them also generate phase shifts, not to mention pre-amplifiers, etc.

When you run a DSP, the question I have is that since the passive components are eliminated and the processing of the signal -could- be done by increasing or decreasing each 'bit' by scaling it's output level, and if that's what's done, does level scaling do anything to the phase, or is the processing done with a mathematical 'curve' that results in a similar shift in phase as the passive components?
