10902A Understanding Public Address System is a comprehensive training platform to learn the operation of Public Address System. It is demonstrator cum training system specifically designed for the comprehensive practical study on Public Address System for the beginners with a basic knowledge of the various electronic building blocks and fundamentals of communication system.

This didactic product develops the sense of investigation within the student and familiarises him with repair techniques/design techniques. One of the main features of this training system is fault simulation to educate on actual fault finding, by simulating faults on this platform. The complete block diagram of Public Address System is printed on the mimic. Finally this equipment allows us to do experiments and to observe waveforms/ signals/voltages of different sections, which are guided thoroughly by theory and product tutorials to gain in-depth knowledge of the system.
