How to configure conference room audio.Xi'an Bar Audio price

　　First of all, the type of speakers is determined according to the needs. Now there are household, professional and broadcast audio systems. If it is a conference room audio system, it is best to use professional audio systems. good.

　　Secondly, the room should do a good job of sound absorption, such as making some sound-absorbing materials on the walls, laying some carpets on the floor, etc., to ensure that the reflected sound of the room is reduced, the reverberation is reduced, and the possibility of howling can also be reduced.

　　Third, determine the sound pressure level to be achieved, and the number and characteristics of the speakers.

　　According to the standard GYJ25-86 "Acoustic Characteristics Index of Hall Sound Reinforcement System", the sound pressure level of the first-level banquet hall and conference room should be greater than or equal to 103dB, and the second-level sound pressure level should be greater than or equal to 98dB.

　　The sound power to be expected in the sound field is about 600--800W.

　　That is to say, if you want to buy four professional speakers, you can distribute two in the front and rear. The best way to hoist is to use ground brackets.

　　Each speaker has 400W---600W, and the sensitivity of each speaker is 98---103dB. In this way, the sound field requirements can be satisfied. If the sound field is required to be uniform, two more speakers with the same index can be added and placed on both sides of the middle position.

　　Fourth, professional speakers need professional equipment to use, first of all:

　　Mixer;

　　Conference microphone (conference microphone with host can be selected, which can be pre-amplified);

　　Handheld wireless or wired microphone (for presenters).

　　Choose according to the number of microphones as appropriate. If it is just a conference, there are 8-channel and 10-channel mixers.

　　Secondly, there must be power amplifiers. It is best to buy two power amplifiers to push four speakers, and three to push six speakers. If the power and impedance are properly matched, two power amplifiers can also push six speakers.

　　If you have enough money, you can add equalizers, effects, feedback suppressors, compressors, and more. If you are too troublesome, you can directly add an equalizer and a digital processor.

　　The easiest way is to connect the microphone---mixer (with effects)---power amplifier---speaker.

　　For brands, we recommend the top ten national brands, Jazz Dragon Audio. The quality and service are relatively guaranteed. You can try it yourself, try the human voice, and listen to the clarity and stability of the language sound reinforcement.
