Introduction to Public Address System

0
0



Public Address System, in short, is the PA system. It is used in many areas, from events to a shopping centre. 

I am specialised in the public address system for buildings which consist of a few hundreds of speakers. Without the proper knowledge, the equipment can be burnt and even cause a fire to happen. 


Line supervision is the technology that helps to protect the equipment from any damages. It will cut off all the linkage if tampering on the line is detected. This prevents the system from overloading or any short circuit from happening. 

With the advancement of the Public address system, troubleshooting is made much easier. Saving on maintenance time and also troubleshooting.
