The difference between professional audio and civil audio technology

　　First, both are constantly striving to achieve the best sound effects.

　　Second, they all need to use audio equipment such as mixing and amplifying information processing (such as balanced mixing effects, etc.), power amplifiers, speakers and various audio sources.

　　3. The system is stable and reliable, and achieves the best performance-price ratio.

　　Fourth, the listening effect is not only related to the performance of the system equipment, but also closely related to the listening environment (sound-building conditions), so it is necessary to care about the sound-building conditions.

　　They are also very different due to different service areas, service objects and usage functions:

　　1. The service area of civil audio is generally less than 50M2, and the service objects are family members and relatives and friends with a small number of people. Therefore, the output power of the power amplifier is required to be small, and the power of the speaker is also small. Pressure sensitivity), directional characteristics, maximum sound pressure level and other index characteristics do not care much, in order to pursue high sound quality, you can spare no effort (especially the fever HIFI system)

　　The service area of professional audio is very large, and the number of service objects ranges from hundreds to tens of thousands. Therefore, special consideration is given to the efficiency and cost of the system, and higher requirements are put forward for the speakers to understand the technical characteristics. System cost, can get the best sound effects and the lowest cost of use. Both "horses are good" and "horses eat less grass".

　　2. Professional audio is widely used in theaters, cinemas, hotels, conference centers, sports competitions, music plazas, entertainment centers, exhibition centers, institutions, schools, airports, ports, stations, subways, and army barracks. Not the same, the system design must be adapted to local conditions, there is no general system matching scheme, and the use of civil audio is single, and the general matching mode can be adopted, which is easy to use.

　　3. Professional audio must adapt to local conditions and carefully consider the system sound field design (speaker layout) in order to obtain good acoustic effects.

　　Fourth, professional audio must design different signal processing methods and signal transmission paths according to the function of use.
