The difference between professional audio and civil audio technology.High-end bar audio Vendor

　　1. Both are constantly seeking to achieve the best sound effects.

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

　　3. The system is stable and reliable, achieving 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 all need to be concerned about the sound-building conditions.

　　Due to the different service areas, service objects and usage functions, they also have great differences:

　　1. The service area of civil audio is generally less than 50M2, and the service targets are family members, 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), pointing characteristics, maximum sound pressure level and other index characteristics are not very concerned. In order to pursue high sound quality, I don’t hesitate to pay for it (especially the feverish HIFI system)

　　The service area of professional audio is very large. The number of service targets ranges from hundreds to tens of thousands. Therefore, the efficiency and cost of the system are particularly considered, and higher requirements are put forward for the speakers to understand the technical characteristics. The cost of the system can obtain the best sound effects and the lowest cost of use. It must be "good horses" and "less horses eat grass."

　　2. Professional audio is widely used in theaters, cinemas, hotels, conference centers, sports competitions, music squares, entertainment centers, convention and exhibition centers, institutions, schools, airports, ports, stations, subways and military barracks, etc., with various functions, venue shapes and acoustic characteristics. Different, the system design must be adapted to local conditions, there is no universal system supporting program, and the civilian audio system uses a single object, and the universal supporting mode can be adopted, which is simple to use.

　　Third, professional audio must be adapted to local conditions and carefully consider the system sound field design (speaker layout) in order to obtain a good acoustic effect.

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