Conference room audio system solutions
We will determine the type of speakers according to your needs. Now there are household, professional, The sound system of broadcasting is different. If you want to do a conference room, it is best to use a professional one. It is not suitable for home use in the conference room. The sound quality of broadcasting is not good.
Secondly, make sure that your room needs sound absorption, such as making some sound-absorbing materials on the walls, laying some carpets on the floor, etc. to ensure the reflected sound of the room Decrease, reduce the reverberation, and also reduce the possibility of howling.
Third, determine the sound pressure level to be achieved, and the number and characteristics of speakers.
According to the national standard GYJ25-86 “Acoustic Characteristics Index of Hall Sound Reinforcement System”, the sound pressure level of the first class banquet hall and conference room should be greater than or equal to 103dB, and the second class should be greater than or equal to 98dB.
The sound power you should expect in your sound field is about 600–800W.
That is to say, you need to buy four professional speakers, two of them can be distributed in the front and rear, the best hoisting, or use the ground bracket.
Each speaker has 400W—600W, and the sensitivity of each speaker is 98—103dB. In this way, your sound field requirements can be met. 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 must be used with professional equipment, first of all:
mixer;
conference microphone (optional conference with host Microphone, can be pre-amplified);
Hand-held wireless or wired microphone (for host).
According to the number of microphones, choose as appropriate. If it is just a conference, there are 8-channel and 10-channel mixers.
Secondly, it is necessary to have power amplifiers. It is best to buy two power amplifiers to push four speakers respectively, and three to push six speakers. If the power and impedance are properly matched, two power amplifiers can also push six speakers. See what brand the owner wants to buy.
If you have the 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??
The price of the whole set is also high and low, the ordinary point is 8000—12000. As for the brand, I think it’s up to you to audition yourself, try the vocals, and listen to the clarity of the language amplification.

The conference room audio system affects the effect of the meeting, a good conference room audio system will save a lot of trouble for the meeting , then what systems should an enterprise’s conference room audio system include? What is the overall solution?
(1) Sound reinforcement system:
The sound reinforcement system consists of mixer, digital audio processor, professional amplifier, professional audio, Wireless microphone, DVD player, timing power supply and other equipment. Complete the processing of various audio signals, realize the on-site amplification of the conference room, and cooperate with the video display system to provide excellent audio-visual effects.
(2) Digital conference system:
The digital conference system consists of digital conference host, chairman machine, representative machine, various management software and other equipment. The digital conference system can provide flexible management for all types of conferences, whether it is an informal small conference or a large international conference with thousands of people in multiple languages. It has the characteristics of multi-function, high sound quality, and reliable digital transmission. The functions of the entire digital conference system include conference discussion and speech, collective voting in the conference, instant multilingual translation of the conference (up to 8 languages), full recording, and access to various audio signals.
(3) Video display system:
The multimedia display system consists of a high-brightness, high-resolution LCD projector and a motorized screen; A large-screen display system for graphic information.
(4) Room environment system:
The room environment system consists of room lighting (including incandescent lamps, fluorescent lamps), curtains and other equipment; The environment and atmosphere of the entire room are changed to automatically adapt to the current needs; for example, when playing DVDs, the lights will automatically dim and the curtains will automatically close.
