Professional sound reinforcement system includes sound reinforcement equipment and sound field composition, mainly including sound source and its surrounding sound environment, the sound into electrical signals of the microphone, signal amplification and signal processing equipment, transmission lines, the signal into acoustic signals of the speaker and the acoustic environment of the audience area.

Sound reinforcement technology has its very unique characteristics:

First of all, it has a very strong on-site nature. Sound reinforcement generally requires real-time control of equipment at the performance site during sound reinforcement. Sound engineers are not allowed to make any mistakes during tuning. Otherwise, it may cause extremely adverse consequences. Therefore, it is necessary to ensure the normal performance of sound system design and on-site tuning.

Second, because the sound reinforcement system includes the whole process of picking up the sound and playing it out, to a large extent, the sound from the speaker can easily be transmitted to the microphone to cause acoustic feedback howling. In other systems, because the sound area of the microphone (sound field) and the sound area of the speaker (sound reinforcement field) are not in the same space, the sound of the speaker cannot be transmitted to the microphone through the space, there will be no sound feedback howling, so sound engineers engaged in sound reinforcement must master the method of eliminating sound feedback. Third, to ensure the safety of the equipment, the sound reinforcement system sound changes, many accidents, a little negligence in tuning, it may lead to the burning of power amplifiers or speakers, causing unnecessary losses, in the system design and tuning should also pay attention to take various measures to minimize the occurrence of equipment burning.

The debugging work of sound engineering needs to be treated with a serious and responsible attitude. Only after ensuring that the design, construction, system structure and stage sound equipment performance are fully understood can a better debugging result be obtained. For the problems that often occur in general debugging work, here we introduce some technical links that should be paid attention to during debugging for your reference.
