The course objective is to provide a basic understanding of these systems, their fundamental components, and how these systems work, and then it explores some of the specific applications of the systems. It begins with lessons on understanding the components associated with distributed sound systems/ paging systems and their functions. Next, it explains the differences between a constant voltage system and a self-amplified system. Single-zone and multi-zone paging systems will also be examined. One of the prime considerations in any sound system design is an efficient power transfer between the amplifier and the associated speakers. There is a lesson designed to explain the two power transfer methods, their advantages and disadvantages. Other topics discussed in this course are designing and layouts and sound masking systems.
