SYSTEM DESIGN GUIDE
SYSTEM DESIGN
Bogen created the System Design Guide (pages 64-77) to help you to understand how a paging system works
and how to set one up. It is filled with helpful information and reference material that is sure to help answer
your questions about centralized 70V amplifier and 24V self-amplified systems and products, how and when
to use them, and how to correctly set them up.
Actually, all you need to design a proper paging system is a few simple measurements. Then follow the step-
by-step process to select the type and quantity of system components needed. At any point you can contact
Bogen’s toll-free Technical Support Department for assistance, or take advantage of Bogen’s Free Applica-
tion Design Service (see page 82).
