How to Design and Choose the Sound Reinforcement System of Conference Room

　　The sound reinforcement system is more complicated than the video display system, because it is difficult for different people to agree on the perception of the senses. In addition, after the audio signal is transmitted, processed, and finally amplified by the speaker, it is difficult to guarantee the product without good quality sound effects, and there are also many on-site factors.

　　In the conference room sound reinforcement system, to design and select the sound system for the conference room, there are the following aspects that need to be paid attention to:

　　The space layout of the meeting room, such as length, width and height;

　　The meeting room types can be divided into round meeting rooms, rectangular meeting rooms, other irregular-shaped meeting rooms, and so on.

　　The country has corresponding standards for sound system design. However, in reality, some meeting rooms did not strictly follow the requirements of architectural acoustics for decoration and decoration at the beginning of construction, which directly led to the subsequent need to spend a lot of money in the design of sound systems. The energy and technical strength of the company went through repeated debugging, and in the end it was not even up to expectations.

　　In the decoration of the conference room, is sound-absorbing material used in most areas?

　　This is similar to the above description. The sound reinforcement effect has two main aspects: one is whether the sound conditions are ideal, and the other is whether the electroacoustic design is reasonable. Among them, the condition of sound construction is the foundation, and it needs to be experienced in person.

　　The selection of the source pickup equipment in the entire audio system includes gooseneck microphones, digital conference microphones, wireless handheld microphones, boundary microphones, etc. It is not recommended to use interface or omnidirectional microphones. It is very difficult to debug and the gain is not open. It's very big, and it's easy to scream. This is when deploying speakers, the choice of location needs to be carefully selected, try to keep a certain distance from the microphone.

　　For audio processing, traditional analog mixers are mostly used. Nowadays, more digital audio processors are used (if the video conference room is equipped with a digital processor with AEC echo suppression function). If you choose digital audio processors, you need to pay attention to it. For operation problems (because the device itself does not have faders or knobs like a mixer), you can choose to have a suitable control panel, or you can connect to an intelligent control system to control it through PAD.
