How to Choose a Suitable Conference System?

Ⅰ. According to the function and composition mode, the general conference system can be divided into:

1. A multi-microphone conference sound reinforcement system mainly composed of a mixer

This is the most widely used and popular conference system. It is well integrated with the sound reinforcement system, the system composition is simple (only refers to the conference sound reinforcement part), only a few microphones are added, and it can adapt to various large, medium and small conference occasions, so it is widely used.

Of course, this form of conference system has a single function, which is only used for speaking and sound reinforcement, and cannot meet the functions of other conference forms. sound processing.

2. Conference system with automatic sound mixer

The basic mode of this kind of conference system is similar to the multi-microphone conference system based on the mixer. The difference is that the multi-microphone signals are automatically mixed and output to a certain channel of the mixer. The so-called automatic mixing is to insert multiple microphones into the automatic mixer. After adjusting the appropriate gain, turn on all the microphones. The mixer can automatically identify which microphone is in use, and then trigger to open the channel for amplification. Input channels for unused microphones are turned off.

The benefits brought by the automatic mixer are: it can automatically open and close the input channel of the microphone to prevent interference, automatically set the appropriate input level, make the sound loudness basically consistent, improve the sound reinforcement effect of the meeting, and reduce the pressure on the sound control personnel.

3. Hand in hand analog conference system

For the above two conference systems, the number of microphones generally used is less than 8, too many will cause inconvenience to use and control. For conference discussion systems with many speakers, the Hand in Hand conference system can meet this requirement.

This type of system consists of a system host, a chairman unit, several representative units (ranging from a dozen to more than a hundred depending on the system) and corresponding sound reinforcement systems. The chairman unit has a microphone, control keys, amplifier Audio speaker unit, etc., can control other representative units: allow or not allow one or all representative units to speak, and control the conference process and topics conveniently.

4. Hand in hand digital conference system

With the advancement of technology, the functional requirements for conferences are becoming more and more abundant, and it is difficult to meet them with analog technology, so a hand-in-hand digital conference system has emerged.

The basic structure of this type of conference system has not changed much, but it can be easily added: functions such as electronic table card, sign-in, recording, control, etc., and the compatibility with simultaneous interpretation and other systems is well controlled, and the stability is improved.

5. Intelligent conference system

Faced with the increasingly widespread use of conference systems and higher and higher functional requirements, the management, control and function expansion of conference systems are very urgent problems to be solved. With the introduction of computer technology and network technology, everything can be easily solved.

The system is composed of such an architecture as the system host (hardware), application function requirements (software), system structure (network), and functional modules (client). The system can greatly expand the functions of various conference forms. Functions such as electronic document circulation, signing and approval, discussion, and voting are conveniently integrated, subverting the traditional conference system.

Ⅱ. We can also divide the conference system into:

1. Wired type

This type of system has the characteristics of simple structure, stable performance, and strong confidentiality, and has a certain market. At the same time, it also has the disadvantages of high wiring costs and difficult to move.

2. Wireless

This type of system is a newly developed and mature new conference system. Depending on the wireless technology used, there are infrared, 2.4G wireless technology, 5G WiFi wireless encryption technology, etc. The characteristics are just the opposite of the wired type, but with the development of technology, its shortcomings will be gradually overcome.

Of course, the above classification is not complete and unique. The main purpose is to let everyone have some understanding of the conference system and its technology, so that we can choose in actual work.
