Regarding use case, it might be nice to have a transparent volume control downstream of a DSP X-over, which would help solving any noise problem at low volume in an audiophile's 3-way active system.
In fact this seems to be the intended use, together with other components from the brand, and should work with a Behringer DCX as well - the noisier, cheaper PA processor, the more benefit.
