The stage broadcasting audio system can be basically divided into four parts: the source equipment, signal amplification and processing equipment, transmission lines and speaker systems.
Program source equipment: The source of the program is usually provided by radio broadcasting, laser singer and recording card seats. In addition, there are speakers and electronic instruments.
Signal amplification and processing equipment: including mixer, front amplifier, power amplifier and various controller and audio processing equipment. The primary task of this part of the device is the signal amplification, followed by the selection of the signal. The role and status of the tuning table and the front amplifier are similar (of course, the function and performance indicators of the mixer are higher). Their basic function is to complete the selection and front amplification of the signal. In addition Adjust and control. Sometimes in order to better balancing frequency and lust, they also invest in the balanor separately. This part is the "control center" of the entire radio audio system. The power amplifier will amplify the signal sent by the front amplifier or the mixer, and then push the speaker to sound through the transmission line.
Although the transmission line is simple, there are different requirements with different systems and transmission methods. For the auditorium, theater, etc., because the distance between the power amplifier and the speaker is not far away, the direct feedback method of low -resistance and large current is generally used. The transmission line requires a special speaker cable. The loss caused by the transmission line often uses a high -voltage transmission method. Due to the small transmission current, the transmission line is not high.
Speech system: The speaker system requires the entire system to match, and the choice of its location must be actual. The auditorium, theater, and the singing hall sound and sound quality requirements are high, and the speakers generally use high -power speakers; and the public broadcasting system, because it is not so high in sound, it is generally better to use 3W -6W ceiling speakers.
