Volume Adaptive Control System for public transportation equipment
Zealous Follower PAGC-52M is able to automatically stabilize audio source by itself, and able to automatically changes PA volume at real-time based on the noise level of the site. Sometimes public places are crowded, sometimes are sparse, in addition, noise level varies with different groups and different times. Therefore, the TV volume must be adjusted accordingly based on the ambient noise level. When noise is high, TV volume will turn up, vice versa, regardless of what kind of TV programs or advertisements. If so, passengers will not feel the TV too loud or quiet, moreover, it will improve overall service quality of our public facilities.
