The power distribution of the soundplay with the main speaker system shall choose the appropriate number of platforms according to the determined number of combination tables, according to the power amplifier without distortion of power conditions. For the driver of the speaker, the front -level division method can be used, or the power frequency frequency method can be used. In order to ensure the rationality and reliability of the speaker system in the hall, the group and wiring technology of power distribution must be treated. In large halls, in order to make the speaker system have a good sense of orientation, it is best to make the audience "see" speakers, so that the visual and hearing orientation is basically the same, because for hearing It's relatively slow. If the appropriate delay is inserted in the main speaker system, the Has effect is used to make the sound image move down.

Make the sound system of the speaker sound and the position of the sound source more consistent, so the listening effect will be improved. The auxiliary speaker system outside the main speaker system generally has different types. For example, the corridor and the rest room should be used as a background music with the top speaker, and the small VIP conference room must be used in a combination speaker or small pillar. At this time, appropriate grouping should be made according to the power, impedance (or voltage), and quantity of the selected speaker, and the necessary parallel is connected to the power distribution board after the necessary parallel processing. According to the total power distribution, the design and power amplifier can switch the connection circuit, and select the backup amplification system to easily control and operate indoors of the tone tunnel in the sound expansion control room. In addition, it is necessary to determine the power of the return system and the monitoring system.
