Figures 17 and
18 show the system architecture of the
mixer unit at the module level. The system is laid out in a modular
fashion, such that it can be expanded and upgraded from an initial
Audio input and output boards mounted to panel-mounted aluminum
brackets, allow reasonably simple upgrades. Audio mix PC boards
can be added to the system as well, however this upgrade process is
slightly more involved, as a different wiring harness is needed to
connect to the boards.

This particular scheme of modularity was chosen for two main
reasons. First, it extends the ability to expand and upgrade
the system. Secondly, there are substantial manufacturing cost
reductions involved due to the duplication of several of the modules.
