The function of the main audio is to play the sound to the listeners, give the audience enough sound pressure, and provide the audience with the real, clear, full and undistorted voice.

The main speaker should have the characteristics of high power, wide band and high sound pressure level. In order to effectively control the radiation of sound waves, high frequency loudspeakers are selected with a horn type loudspeaker with strong directivity, and some medium loudspeakers used for outdoor sound expansion are also used as a trumpet type. There are two main types of main loudspeaker systems: one is a full band sound box for a small sound amplifying system, consisting of a horn soprano and a medium and low bass paper basin speaker, and a loudspeaker system consisting of a high school and low multi unit loudspeaker. The other is a sound amplifying system composed of audio boxes made by each frequency band. It uses electronic frequency division network, amplifies each frequency band alone, and also combines the sound box with the medium and low sound loudspeakers and the independent hyper bass box.

As most of the actors and band members perform on the stage, and the main speaker is on both sides of the stage, it is hard to hear the performance on the stage, and it is difficult to find the actors and players if they do not return the speakers.
