Our professional line array speaker system has been applied to the playground of Jiuzhaigou Middle School in Sichuan Province, China.
Project Background
Jiuzhaigou Middle School is a experimental teaching model school in Sichuan Province, covering an area of 162.2 acres. It has a newly built complex building integrating teaching rooms, music rooms, dance rooms, art rooms, multimedia rooms, and academic lecture halls, a standard plastic playground with eight running tracks, and a football field with artificial turf, with the playground covering an area of 20,689 square meters.
With regards to high requirements of the school for sound reinforcement system, DSPPA has designed an overall solution integrating professional sound system and digital conference system, which not only solves the problem of sound uniformity and speech intelligibility, but also facilitates convenient, flexible and efficient system operation.
LA1420 line active array speaker system is characterized by wide radiation angle, strong sound penetration, high sensitivity and high sound pressure level. Combined with LA1420S subwoofer, the system can be complemented for full sound pressure headroom and uniform sound field, creating an enabling environment for sound reinforcement.
Two groups of DSPPA linear array speakers, consisting of 6 passive line array full-range speakers and 1 passive line array subwoofer, are used as the main speakers, which are symmetrically installed on both sides above the platform, covering the main listening area in the middle of the playground.
The line array speakers are complemented by four outdoor column speakers above the platform, so that the entire playground is covered without dead corners. The desktop speaking unit can be flexibly matched with multiple wireless microphones to meet the needs for speech and cultural and sports performances during meetings.
Emphasizing physical education is the foundation of a strong country. DSPPA overall solution designed for the playground of Jiuzhaigou Middle School meets various needs of setting-up exercises, various sports competitions, cultural and sports performances, and school meetings, and plays an important role in promoting all-round and healthy development of physical and psychological quality of young people.
