Q-SYS Makes its Mark at Asian Games

The recent opening and closing ceremonies to mark the 16th Asian Games, held on Haixinsha Island, Guangzhou, differentiated from similar events seen previously - with the spectacular event making the city as the background and the Pearl River as the stage. In fact the event started on the river, with a ship sailing from east.

n order to make the ceremonies a success, the island was equipped with a series of highly intelligible public address systems, with QSC’s premium Q-Sys control chosen to provide tourists from all over the world with crystal clear sound reinforcement.

A Q-Sys network provided coverage to every corner of the island, with a powerful Q-Sys Core as the engine, and Q-LAN’s low-latency Gigabit Ethernet network implementation as the transmission network.

There were eight control rooms on the island, two of them based centrally and the remainder as satellites. With their huge processing capacity, two Core3000s provided back-ups for each other in the two central technical rooms.  This redundancy meant that should any failure have occurred in one, the system would automatically have switched to the other (this feature greatly enhancing the reliability of the system). Other networking audio interfaces were placed in the auxiliary control rooms to feed signals to the nearby loudspeakers.

The system was programmed with the background music running according to the playlists and transmitted to the decks, fountain area, dock and gardens. These were played out through 534 specially treated QSC AD-S loudspeakers - these weatherproof loudspeakers guaranteeing the safety of the system in an extremely rainy city.

Aside from providing the background music function, the QSC Q-Sys was also linked to the emergency evacuation and fire alarm system.

In the security centre, fire centre and service counter, 11 PS-1600H networked page stations were installed; this enabled operators to broadcast paging announcements manually.

The networked page stations feature capacitive touch, programmable keypad and 240 x 64 graphics LCD for flexible customisation: the audio and control signals are connected to the Q-LAN network through a gigabit Ethernet Cat5 cable, while the page stations are routed and managed by the Core, and can use both use Power over Ethernet (PoE) or local power supply.

Other than the Public Address functionality, the system can also record announcements and trigger playback of pre-recorded announcements. The Fire Alarm functions are fully integrated into the system, which will be automatically triggered once any fire accident occurs.

The eight control rooms on the island were equipped with large quantities of equipment, distributed to the many different zones including underground. All equipment on the network was under the command of the Q-Sys, and its remote controllability was not only very efficiency but also provided substantial cost saving.

As planned, following the Games the Haixinsha Island is being transformed systematically to a large garden, and the underground area will be reconstructed as a museum.

Although the functionality has varied extensively before and after the Games, Beijing Oriental Prime Connections Film/TV Technology Co., Ltd., took everything into consideration with their initial design. Since Q-Sys is a universal (and extremely flexible) networking platform, the coverage has been extended and local residents and tourists alike will continue to receive high quality public address services.
