1.Power distribution of audio system
For speaker drive, you can use the front-end frequency division method, or power division method. In order to ensure the rationality and reliability of the speaker system in the hall, special treatment must be made in the grouping and wiring technology of power distribution.
In large halls, in order to make the speaker system have a good sense of orientation, it is best to make the audience "see" the speakers, so that the visual and auditory orientation is basically the same, because for the sense of hearing, the horizontal orientation is more sensitive, and the vertical orientation Relatively late pure..
If you insert an appropriate delay in the main speaker system, use the Haas effect to move the sound image down, and make the orientation of the speaker sound system and the sound source more consistent, then the listening effect will be improved.
The auxiliary speaker system of the main speaker system generally has different types. For example, ceiling speakers are used for background music in corridors and lounges, and combined speakers or small columns are used in small VIP conference rooms.
At this time, it should be appropriately grouped according to the power, impedance (or voltage) and number of the selected speakers, and connected to the power distribution board after necessary parallel and series processing. According to the total power distribution, a switchable connection circuit with the power amplifier is designed, and a backup amplifier system is selected so that it can be easily controlled and operated in the sound reinforcement control room. In addition, the power of the listening system and the monitoring system needs to be determined..
音响功率分配很重要,搞不好主扩、返听、监听“闹意见”!
