Due to the large venue for 10,000 people, the sound pressure level should be uniform. So DSPPA applied the combination of digital column speaker and professional array line speaker.

Super large venues require stronger technical support

 

Compared to the traditional speakers, the directivity Q value of phased array loudspeaker is high, and its acoustic direction can be electronically adjusted, mounted vertically on the site column, and is very coordinated with environment.


In order to improve the vertical directivity, two phased array loudspeakers are used in one group. There are two groups on each pillar, one radiating to the left and the other to the right rear. The audio signal can be effectively improved by the delay of the processor, and the natural cover of the column can prevent the sound behind the post from interfering with the front sound. So through the solution, the problem of decreasing the sound clarity caused by the increase of points is solved.
