Just to be clear on this, if DSP DRC requires a 3dB boost (at any frequencies), it will reduce the overall level by 3dB first to ensure that there is enough headroom for the boost without inducing clipping.
If DRC determines a 3dB cut is required then it will achieve this cut by reducing the level at the relevant frequencies - that's what a "filter" does - frequency-dependant level reduction. So, digital attenuation is a given with DRC. In practical applications, DRC can require up to 10dB of boost/cut depending on how the speakers and room are sounding. Digital XO's will also often require cut for one or more drivers, to compensate for the unequal frequency response of the drivers - if your passive XO has a resistor or l-pad in it (usually on the tweeter) this needs replicating with digital attenuation. Of course a digital (or active) XO can do something that a passive can never do and that is boost the signal to a driver...but it can only do this if there is headroom and that usually means an across the board cut in level first... -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
