The large-screen display for the rostrum of a military unit's playground

The display system for the rostrum of the playground mainly includes the display system and supporting audio-visual equipment, including LED large screens and sound reinforcement systems.  

(1) LED Display Screen  

One LED display screen for the rostrum, together with video processing equipment and other supporting devices, adopts a P3 full-color LED display for daily use.  

 (2) Sound Reinforcement System  

The sound reinforcement system uses outdoor waterproof speakers, including devices such as power amplifiers, audio processors, feedback suppressors, and wireless microphones. It needs to meet the requirements of speeches on the playground and sound field coverage of the entire playground, while ensuring the communication security of meetings.
