Implementation Public Address System Design Based on Audio Over Ethernet (AoE)

Disaster management that occurs in high-rise buildings is an urgent need to avoid injury and loss of life. Pelita Harapan International School is an international school that has several building units with hundreds of students. The student evacuation information system in the face of disasters uses a Public Address System such as public announcements, fire alarms, earthquake alarms or other emergency alarms. However, there are constraints such as limited coverage between the PA system and analog amplifiers in the building connected to the central office resulting in signal loss, increased audio sources, and accuracy of zone selection. The purpose of this study is to create a device that can communicate with other IP-based PA system devices such as PA System Network Controllers as servers, remote microphones, or other devices that use IP addresses using the on going system analysis method. The solution presented is the use of an Internet Protocol (IP) network-based PA system amplifier using Audio over Ethernet (AoE) technology, where remote microphones in different buildings have the same function to convey emergency and alarm information to all zones selected to be Novelty. This research. Furthermore, the IP address segment is divided into subnets to represent different buildings. The result of this research is the implementation that has been carried out in the Pelita Harapan International School building with satisfactory results.
