DAS sound system installed at Hangzhou Tennis Center

The historic city of Hangzhou, capital of Zhejiang province, is preparing to host the 2022 Asian Games in the largest Olympic Sports Center of its kind in China. The Tennis Center, which belongs to this complex, has recently been inaugurated with the support of DAS Audio systems.

The sound system was put to the test at the official inauguration of the stadium for the 14th Fina World Swimming Championships held from 11th to 16th December 2018. The DAS system delivered sound at the opening and closing ceremonies.

The team at DAS Audio China worked closely with the local engineering contractor and both sides collaborated in the design and completion of the installation, which has been specially tailored for this multi-sport stadium.

The stadium boasts a tennis court for the finals, which can accommodate 10,000 spectators, two venues for semifinal matches with 2,000 seats respectively, and a 6,000-seats temporary swimming pool constructed on top of the main arena. The rotary retractable roof formed by 8 steel “petals”, which can be opened or closed depending on weather conditions, required a weather-resistant audio system.

For this reason, the HQ series speakers with IP54 certification were chosen for the installation. In addition, DAS’ latest DX (100I/80I) series digital amplifiers with built-in DSP processors and Dante transmission protocols were installed to improve reliability and stability.

The system at the Tennis Center was distributed throughout the facility on 4 clusters of 2 x HQ212.95 flown over the east and west spectator stands, 12 clusters of 2 x HQ212.95 flown over the north and south spectator stands, 6 clusters of 2 x HQ212.95 flown over the main arena, 4 clusters of 4 x HQ212.64 flown over the VIP spectator area, and 2 x Vantec12 as floor monitors in front of the podium.
