example, the loudspeaker processor could maintain a
table of specific loudspeaker models with crossover,
equalization, and delay settings for each model.
Offloading this function from the multifunction DSP
frees valuable outputs and software resources and may
even reduce overall system cost, Fig. 34-49.

System Design

DSP does more than simply replace traditional analog

devices in a system design. DSP gives the system

designer two important new capabilities.

First, DSP is programmable. That means the

designer can set up more than one system design and

give the user the ability to switch between “designs.”

For example, the system could be equalized for both a

full house and an empty house with a button push to

switch between these curves. Or, the system at a reli-

gious facility could be optimized for a wedding or

funeral or typical religious service with a button push to
