Conference audio system solution.Bar audio set Vendor

　　For conference audio, we have to decide the type of speakers according to your needs. There are now home, professional, and broadcast audio systems. If you want to make a conference room, you’d better use a professional one. The home audio system is not applicable in the conference room. The sound quality of the class is not good.

　　Secondly, the conference audio determines that your room should be sound-absorbing, such as making some sound-absorbing materials on the walls, laying some carpet on the floor, etc., to ensure that the reflected sound of the room is reduced, reverberation is reduced, and the possibility of howling can also be reduced.

　　Third, the conference audio determines the sound pressure level to be achieved, and the number and characteristics of the speakers. According to the national standard GYJ25-86 "Acoustic Characteristic Index of Hall Sound Reinforcement System", the sound pressure level of first-level banquet halls and conference rooms must be greater than or equal to 103dB, and the second-level must be greater than or equal to 98dB. The sound you need to expect The power should be around 600-800W. In other words, you have to buy four professional speakers, two of which can be distributed in the front and back. The best hoisting is also possible by using ground brackets. Each speaker should have 400W---600W, and the sensitivity of each speaker should be 98---103dB. In this way, your sound field requirements can be met. If the sound field is required to be uniform, two more speakers of the same index can be added and placed on both sides of the middle position.

　　Fourth, professional speakers must have professional equipment to use, first of all: a mixer; a conference microphone (a conference microphone with a host can be used, which can be pre-amplified); a handheld wireless or wired microphone (for the host). Choose according to the number of microphones. If it's just a conference, there are 8-channel and 10-channel mixers. Secondly, there must be a power amplifier. It is best to buy two power amplifiers to push four speakers and three to push six speakers. If the power and impedance are matched properly, two power amplifiers can also be used to push six speakers. It depends on what brand the landlord wants to buy.

　　If you have sufficient funds for conference audio, you can also add equalizers, effects, feedback suppressors, compressors, and so on. If it is troublesome, just add an equalizer and a digital processor. The simplest is to connect the microphone-the mixer (with effects)-the amplifier-the speaker. The price of a full set is also high and low, with ordinary points ranging from 8,000 to -12,000. For the brand, I think you should try it yourself, try the human voice, and listen to the clarity of the speech sound reinforcement.
