Hongyangdong Scenic Area is located on the mountainside of Yuanling, Fenyi County, Xinyu City, Jiangxi Province. It belongs to the northwest of Xiannu Lake National Tourist Resort. It is a natural landscape scenic spot with karst lava landform as its core. Historically, it is famous for its alchemy efforts by Ge Hong and Lou Yang in the Eastern Jin Dynasty and the book stories of Yan Song's youth in the Ming Dynasty. The cultural sites discovered in the Shang and Zhou Dynasties in 1999 have been listed as municipal cultural protection units. The scenic area regularly holds Wa customs performances and festival-themed activities. Scheme design: Since the occasion is outdoors, all sound reinforcement speaker equipment is customized fully waterproof speakers. The left and right main amplifiers use only dual ten-inch linear array speakers, which are arranged on both sides of the outdoor square for sound reinforcement. This venue often has the demand for event performances, and performances require a certain sense of shock and large dynamic capacity. Therefore, we equipped two two-inch subwoofers, which are placed on both sides of the stage on the floor. We also designed and configured echo speakers. Only a single 15-inch mobile echo speaker is evenly placed and installed at the front of the stage to amplify the sound towards the center area of the stage, so that the performer can hear his voice in time and adjust the volume, pitch and rhythm according to his voice performance.
