The broadcast design requirements embodied in this scheme are the basic needs of the school broadcasting. In the process of broadcasting design, the key function to consider is how to connect the broadcast sub control room with the broadcasting main control room in the playground. The audio signal output from the sound source device itself is too low to carry out long distance transmission, so it is not possible to carry out the long distance transmission. Use a special long-distance audio transmitter. Loudspeaker distribution: 2 wall mounted speakers in each floor of the teaching building, 1 hanging speakers in each classroom, and 1 hanging speakers in each teacher's office. 5 outdoor all-weather waterproof sound columns are placed on the playground.

The system can play the functions of timing music, partition broadcasting, partition paging, division control, unmanned and so on. It can be said that the school is more classic public broadcasting system design. In this system, the emphasis should be paid to the application of "long distance audio transmitter TG-1000A/B". This application is not only mentioned in this system. The scope of schools can also be applied to other similar environments. This is a more economical type selection design for broadcast coverage.
