Hangzhou Olympic Centre

Tailored sound systems for the 2022 Asian Games





The sound system was put to the test at the official inauguration of the stadium for the 14th FINA World Swimming Championships (25m) held from 11th to 16th December 2018. As expected, DAS´ sound system rose to the occasion delivering consistent high-performance sound at the opening and closing ceremonies. The system provided wide coverage and exceptional audio quality, which helped the organizer perform successfully this important international event. 

The Tennis Centre at the Hangzhou Olympic Sports Centre is set to become a reference for local and international sporting events, therefore its sound system not only had to match the unique and modern design of the facility but also had to ensure safety and reliability. The team at DAS Audio China worked very 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. In record time, the sound amplification system was set up and adjusted to the highest standards to provide clarity and intelligibility in all seating areas. 

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 versatility of the Tennis Centre and the unique design of its roof posed a challenge for the acoustic installation since it was necessary to guarantee wide coverage, consistency and high performance in all the seats. The impressive rotary retractable roof formed by 8 steel “petals”, which can be opened or closed depending on weather conditions, required a weather-resistant audio system to perform to the highest level regardless of the position of the roof. 

For this reason, the HQ series speakers with IP54 certification were chosen for the installation. The HQ series are specially designed for medium to large size installations offering tightly controlled coverage patterns, long-throw and high output capabilities. Besides, their cutting-edge interior and exterior coatings are made for weather resistance and extended durability in extreme environments. In addition, DAS´ latest DX (100I/80I) serie digital amplifier with built-in DSP processor and DANTE transmission protocol were installed to improve reliability and stability. 

Providing wide coverage was also essential to enhance the acoustic experience at the Tennis Centre. To this end, the system was precisely 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. 

Once again, DAS Audio has firmly positioned itself as a committed and first level provider of professional sound solutions, delivering systems conceived specially for the task.
