The Audio Control Unit is the main unit of the system. It routes
the selected music, adjusts levels, combines rooms, handles
communication (between wallplates, map, and monitor pan-
els), and can route audio to other ML-116s. It also controls
the paging function.
Refer to Figure 1 for the following discussion.
The ACU RA2 module provides the audio interface for two
rooms. All RA2 modules are fully interchangeable. The mod-
ule identifies the two rooms by an ODD and EVEN nomen-
clature. The numbers that appear on the top of the ACU mod-
ule slot refer to the room's number in the system. These num-
bers also correspond to the numbers in each room drawn on
the map panel.
