How to connect the audio equipment in the disco?

At present, the application of audio equipment is very extensive, and one of the most widely used audio equipment in various industries is our discos and dance halls. Because there are many devices used in these places, it is necessary to make more efforts in configuring connections. What I want to learn from you today is the related problems of equipment configuration and connection in disco professional audio technology.

? Let's first look at the basic requirements of this place for these contents:

? ① The total noise sound pressure level, frequency transmission characteristics, sound transmission gain and reverberation time should meet the national industry standards.

? ② The defects of mute need to be achieved: no vibration phenomenon, silent dyeing, silent focusing, no trembling echo, silent shadow area and dead spot.

? (3) Audio-visual images are consistent, and students always come from the performance or the orientation of the picture.

? ④ Stereo reproduction effect is obvious.

? ⑤ Good sound quality, fullness, roundness, kindness and hearty, with a certain sense of delicacy.

? Next, let's look at the configuration of the sound reinforcement equipment:

? ① We need to configure a 24-channel mixer.

? ② Necessary sound reinforcement system: main sound reinforcement system, auxiliary sound reinforcement system, stage feedback system and sound control room monitoring system.

? (3) Other equipment are

? First of all, let's look at the main sound reinforcement systems: voltage limiter, delay device, room scale, feedback suppressor, electronic frequency divider, power amplifier, high-low split speaker, reverberation effect device, exciter and so on.

? Secondly, let's look at the auxiliary sound reinforcement system: this system is the same except that there are no high, medium and low split speakers, reverberation effectors and exciters, as well as high, medium and bass speakers.

? The stage feedback system includes: voltage limiter, room scale, feedback suppressor, power amplifier and full-band monitoring speaker.

? Monitoring system of sound control room: power amplifier and monitoring speaker.

? The connection skills of these devices are shown in the following figure:
