[Abstract]:
On December 19th, the cultural and artistic evening party to celebrate the 20th anniversary of the return of Macau to the motherland-"The Love of Mind River in China" was grandly held in the Macau East Asian Games Stadium. Xi Jinping, General Secretary of the CPC Central Committee, State President, and Chairman of the Central Military Commission watched the performance. The whole party was exciting and climaxes, winning applause from the audience.

The audio system project of this event is jointly responsible by the technical team composed of Beijing Tianyun Starlight Culture and Art Co., Ltd. and d & baudiotechnik.

The event was held at the Macau East Asia Stadium. The unique venue is an important issue to consider. The ceiling of the stadium is an asymmetric structure. The ceiling is high on one side and short on the other. The side walls of the stands on both sides are also different. There are many reflective surfaces in the stadium, especially the rear wall surface of the stand where the venue is built. There are both walls and glass, which makes it difficult to completely avoid the angle calculation. If you simply use the angle of the speakers to avoid the wall surface, the coupling of the line array speakers will cause problems, so you will miss the other. Therefore, the technical team proposed to install curtains (must be pleated) on the wall to absorb and diffuse the sound arriving here to reduce the reflected sound.


The main expansion system of the party selected d & bGSL system line array speakers. On the scene, 20 GSL8 and 4 GSL12 speakers were hung, and 8 J8 speakers were used for side fill, further improving the uniformity and clarity of the sound reinforcement. In order to effectively control low-frequency coverage and achieve cardioid direction, so that low-frequency energy is more concentrated in the listening area, six SL-SUB subwoofers are used.
In addition, the on-site audio system also uses d & b's ArrayProcessing line array optimization processing technology application, so that the first to last uniform drop is within 6dB, and the goal of completely uniform sound pressure and tone color is achieved. The d & b system is connected through the DS10 audio network bridge, and some long-distance connections are realized through optical-to-network conversion. Because the non-covered area of the GSL system is extremely clean, the microphones on the orchestra and the stage can achieve high sound transmission gain, and the signal is clean and the signal-to-noise ratio is high. With the help of the dazzling lights, the speaker's shocking audition effect not only immersed the guests and the audience at the scene, but also impressed the performers.
As an important dedication party to celebrate the 20th anniversary of the return of Macau to the motherland, the mission was successfully completed after careful design by the audio production team, rigorous on-site installation and deployment, and careful debugging. d & b is praised for its consistently stable system and excellent sound quality.
