What is a "hand in hand" conference system?

In the selection of conference system products, we often see the concept of “hand in hand”. What is the hand-in-hand conference system? As we all know, the conference system is a common application in professional audio systems, which is sound transmission, sound reinforcement, etc. A collection of features designed to provide device support for meeting scenarios. With the advancement of technology, the conference system is constantly improving. From the very beginning, it can only transmit sound. Now it has developed into a comprehensive intelligent sound system that supports voting and evaluation, remote video and even control of the central control.
The concept of “hand in hand” is not a functional concept, but a description of the structure of the conference system. The hand-in-hand conference system is different from the traditional conference system. The traditional conference system generally uses a wired microphone or a wireless microphone, and a professional conference amplifier and conference speaker can complete the conference sounding task. When there are many people who need to speak at the same time, the microphone is often transmitted. If you want more than one person to speak, you must have a few more microphones.

Hand in hand conference system

In the circuit structure, the microphone of the traditional conference system is a radial connection, that is, the microphone line starts from the mixer, and several microphones are connected to the microphone at the end. When the radial structure is actually used, since each microphone is connected to the mixer with one line, the lines coming out of the mixer are many and complicated, and it is easy to pull, entangle, knot, and difficult to manage; Relatively troublesome. However, the traditional conference system also has its advantages: the failure of one microphone does not affect the use of other microphones.
The hand-in-hand conference system adopts the method of connecting the microphones in series at the beginning and the end. After the first microphone is connected to the conference host, a line is taken from the first microphone to connect the second microphone, and then a second microphone is taken out. The line is connected to the third microphone, which is connected in series by dozens, so it is named after the hand-held conference system; all microphones are powered by phantom power. The hand-held conference system's amplifier and speaker section are the same as the traditional conference system, except for the conference microphone and conference host. The hand-in-hand conference system consists of a conference host (also called a central processing unit), a chairman unit, a representative unit, and a branch connection line. The advantage is that it uses a series connection, the wiring is simple, and there is mutual control function; but if the middle one microphone is broken, the subsequent microphone may be invalid.
With the advancement of technology, the failure rate of professional audio equipment is getting lower and lower, and some shortcomings of the serial mode are gradually overcome. So, today, the hand-in-hand conference system is gradually improved by the advantages of easy construction, easy maintenance and powerful functions. Become the mainstream conference system structure.
