The Guangzhou Asian Games unprecedentedly set the opening and closing ceremonies on the ship-shaped island in the Pearl River - Haixinsha Island. To ensure the smooth opening and closing of the Asian Games, the entire island was equipped with an intelligent network audio broadcasting system, integrating beautiful music into the scenic surroundings, providing a comfortable and pleasant ecological tourism environment for audiences and tourists from all over the world.
This background broadcasting system uses a full range of products from the American company QSC, with the Q-SYS network audio system at its core, covering the entire Haixinsha Island through a star-shaped fiber optic network. Various background music is transmitted to the machine rooms outside the island according to a scheduled playlist, amplified locally, and then broadcasted to different zones such as the stands, fountain performance area, docks, and other garden areas. Unlike the public address speakers used in the past, this project adopts QSC's AD series all-weather speakers, which provide tourists with a beautiful and comfortable, immersive listening experience with their excellent musical expressiveness and artistic appeal.
In addition to the background music playback function, this system also includes temporary command broadcasting and fire alarm broadcasting functions. In the security command center, the entrance area of the opening ceremony, and other locations, network call stations are set up, allowing staff to conduct on-site command and dispatch according to their authority through the network call stations. This system is seamlessly connected to the fire alarm system. Upon receiving the dry contact signal from the fire alarm system, it automatically broadcasts fire alarms in the relevant zones.
To enhance system reliability, a dual-machine hot backup function is used. The broadcasting system has two main machine rooms, with two Q-SYS system hosts placed in each room and set to work as backups for each other. If one host or machine room encounters a problem, the other host automatically goes online to work, ensuring the system's normal operation.
