How to design and choose conference room sound reinforcement system

　　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 loudspeaker, it is difficult to guarantee the sound effect of the product without good quality, 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, the following aspects need to be paid attention to:

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

　　Conference room types can be divided into circular conference rooms, rectangular conference rooms, other irregular-shaped conference rooms, and so on.

　　Sound system design, the country has corresponding standards, but in reality, some conference rooms did not strictly follow the requirements of architectural acoustics at the beginning of construction for decoration and decoration design, which directly led to the need to spend a lot of money in the subsequent design of sound system. The energy and technical strength to debug repeatedly, and finally even failed to meet expectations.

　　Is the decoration of the conference room using sound-absorbing materials in most areas?

　　This is similar to the above description. There are two main aspects of sound reinforcement effect: one is whether the sound construction conditions are ideal, and the other is whether the electro-acoustic design is reasonable. Among them, the construction of sound conditions is the foundation, which needs to be deeply experienced.

　　The selection of pickup equipment at the source 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 later, and the gain cannot be turned on. It is very large and prone to whistling. This is when deploying speakers, the choice of location needs to be carefully selected, and try to keep a certain distance from the microphone.

　　For audio processing, analog mixers are traditionally used, and now more digital audio processors are used (if the video conference room is a digital processor with AEC echo suppression function). If you choose a digital audio processor, you need to pay attention to its Operation problems (because the device itself does not have faders or knobs like a mixer), you can choose to have an adaptive control panel, or you can access the intelligent control system to control it through PAD.

　　Then there is the choice of power amplifiers and speakers. The conference room has a high frequency of use, and language sound reinforcement is the mainstay. The floor height of the conference room is generally not high, and users have high requirements for space utilization. At present, the linear sound column speakers can guarantee the use of language sound reinforcement in the conference room in terms of aesthetics, installation and effects, but when choosing, also pay attention to the low frequency part of the sound column speakers. Most of the low frequency parts of the sound column speakers are not Enough. At the same time, the main speakers, fill speakers, etc. are also reasonably configured based on site factors. For example, the main speakers use column speakers, and the fill speakers use ceiling speakers.
