The distribution of audio power is very important, so it's impossible for the main amplifier, return listener, and monitor to "noise opinions"!

The power distribution of the main speaker system for sound reinforcement should be based on the determined number of combinations and the power amplifier without distortion power conditions, and the appropriate number should be selected. For the speaker drive, the pre-frequency division method can be used, or the power frequency division method can be used. In order to ensure the rationality and reliability of the sound box system in the hall, special treatment must be made in the grouping and wiring technology of power distribution.

In a large hall, in order to make the speaker system have a better sense of orientation, it is best to enable the audience to "see" the speakers, so that the visual and auditory orientations are basically the same, because for hearing, the sense of horizontal orientation is more sensitive, while the sense of vertical orientation is more sensitive. It's relatively late.

If an appropriate delay is inserted into the main speaker system and the Haas effect is used to move the sound image down, so that the speaker system and the sound source are more aligned, the listening effect will be more improved.

Auxiliary speaker systems other than the main speaker system generally have different types. For example, ceiling speakers should be used for background music playback in corridors and lounges, and combination speakers or small sound columns should be used in small VIP conference rooms.

At this time, the speakers should be properly grouped according to the power, impedance (or voltage), and quantity of the selected speakers, and connected to the power distribution board after necessary parallel and series processing. According to the overall power distribution, design the switchable connection circuit with the power amplifier, and select the backup amplifier system, so that it can be conveniently controlled and operated in the sound reinforcement control room. In addition, it is necessary to determine the power of the back-to-listening system and the monitoring system.
