The conference microphone seems to be a simple individual, but it is not. It is a powerful audio-visual system composed of a variety of rich equipment. Only when the conference system is configured according to the different needs of customers can the conference system give full play to its greatest advantages. There are three ways to configure the current common conference microphone:
1. Conference microphone + mixer
The main type of conference microphone + mixer is mainly used in occasions that require high sound quality. It has the advantage of relatively good tone reproduction, but the number of microphones in this way should not be too much, generally about 100 square. If the number of conference microphones increases, the problem of howling is inevitable. If it is solved by processing equipment, not only the sound quality is sacrificed, but the sound transmission gain cannot be raised. In this way, the advantages of this configuration method have been turned into disadvantages. Secondly, if this configuration method is equipped with a processor to resist howling, the overall cost will increase, and the cost performance is not as high as the other two methods; again, as the most traditional way of meeting speech, its functions cannot be expanded, such as meeting intelligence. Management, camera tracking, simultaneous interpretation and other functions. This method still has practical applications, mainly in lecture halls, training halls and other places.
2. Conference microphone + smart mixer or conference microphone + audio processor
Conference microphones + smart mixers are mainly used in occasions where there are a large number of microphones (more than 5) and the project cost is not too high. The advantage of this configuration is that howling is suppressed to a certain extent, and at the same time, the microphone at the conference site can be intelligently managed. The camera tracking function can be realized through the central control or camera tracking processing, but the shortcomings are also obvious. First of all, each microphone needs A microphone cable, the more the number of microphones, the more wires need to be laid, and the workload of construction and debugging is huge; secondly, although the sound transmission gain has been improved to a certain extent, the effect of commonly shared by more than a dozen microphones is still not ideal; again although The intelligent management of the conference site is realized, but to expand the functional requirements of other conference sites, other functional equipment is needed to realize it, and the cost performance is not too high. This method is mainly used in video conferences where there are not many people, small meeting rooms where audio and video signals need to be recorded, larger interactive training rooms, reception halls and other places.
3. Hand in hand digital conference microphone method
It is mainly used in a large number of microphones, from small conferences with several conference microphones to large-scale conferences with hundreds of conference microphones. It can be realized from a single voice speech to multilingual speech speech. It can be set up on the conference site through the hardware itself or management software to effectively manage the conference. It can also expand the need for sign-in, voting, embedded installation and other functions. Its advantages are that the comprehensive function needs of the meeting can be met, which can ensure effective control of the effect of the meeting; the wiring is convenient, a dedicated digital conference microphone line can connect about 20 microphones; the control method is flexible; the scalability is strong, and the cost performance is high. . Although the sound quality of a single microphone is not as good as the first method, the overall effect is better than the first method under the premise of using the same number of microphones. This method has been widely used in various types of conference venues and has become the mainstream configuration for conference speeches.
Each of the above three methods has its advantages and disadvantages. We can't just pursue economical benefits when selecting and matching. It is best to listen to the suggestions of professionals to use conference microphones to maximize the use value.
