1. Centralized layout:

Speakers are centrally arranged on both sides of the stage.

Advantages: convenient and practical, simple connection, less wires, accurate sound direction positioning and natural sound reinforcement.

Disadvantages: it is easy to cause howling and the microphone volume is not turned on.

Application places: indoor art performances, small song and dance halls, clubs and multi-functional halls.

2. Decentralized arrangement:

Several ceiling speakers are installed on the ceiling in a decentralized way, or several speakers are installed on the wall and behind the seat. be careful! The speaker shall be pointed and its distribution range shall be limited. When using ceiling speakers, I hope the ceiling is lower.

Advantages: the direct sound ratio is improved, the sound pressure distribution is uniform, and it is not easy to cause howling.

Disadvantages: poor sense of sound direction.

Application places: voice playback, hall sound reinforcement, square sound reinforcement, playground sound reinforcement, multi-functional hall language sound reinforcement.

3. Centralized ~ decentralized layout:

The layout is mainly centralized and supplemented by decentralized. Music, cinemas and other sounds requiring accurate sound direction shall be played centrally, and language amplification shall be played separately.

Advantages: it integrates the advantages of centralized and decentralized.

Disadvantages: complex system and high cost.

Application: suitable for all occasions.

4. Linear array:

Linear array speakers are designed for large-scale outdoor performances. Recently, a small product is suitable for indoor performances. It is characterized by sharp directivity. The vertical radiation angle of each speaker is only 10 ~ 30 degrees, and the speaker angle can be accurately adjusted. The attenuation per multiple distance is as small as 3dB. It is suitable for large conference multi-function halls with high requirements.

5. Precautions:

When the distance between the two speakers is greater than or equal to 17 meters, that is, the time difference between the sound to the human ear is greater than 50 ms, a "delay device" must be added to the system. Otherwise, reverberation will occur and the sound will not be heard clearly.
