Only hidden because you choose not to look.     Say I was running a 
venue that has a noise ordinance applied to it, or the health and safety 
regulators have imposed maximum noise levels.  I could insert a limiter 
there to ensure no matter how high the DJ turns up his volume, I don't 
have to pay the fines for for his or her excessive volume levels.

Perhaps I have a room that can be reconfigured, and this reconfiguration 
changes the accoustic properties of the room.  I could insert an EQ and 
reverb unit here with a couple of different settings for the different 
room configurations.    Say a church that opens up it's windows in the 
summer, but closes them when the weather isn't so nice.

   There are many other scenarios where this capability is useful.
