As a more complex type of Technology Engineering, sound engineering in may occur in a variety of problems, coupled with sound and lighting system equipment type and quantity, and the technical requirement of the system also differ in thousands of ways, so the occurrence of various problems are inevitable, often encounter some difficult problems.
According to the characteristics of audio engineering, engineering design to project quality and progress plays a main role, so as long as the construction seriously according to the design and relevant norms of conduct, is generally not in the construction process of any problems, or that these difficult problems will not be reflected in the construction. In most of the time, engineering problems occurred during commissioning, even with the use of a period of time to show. Since it is a difficult problem to solve, it is very easy, often bother to check for a long time, problems still exist; some problems be rather baffling is lost, then I do not know when it happened, make people very headache, presumably every engaged in audio engineering technology make people will have different levels of experience. But while these problems is through a variety of forms, but as long as the design without error, it can be said that the origin of the only one, is: construction link omissions. So, even if the problems can be solved, or the. The common part of the typical problems, according to the author's practical experience, with the diagram analysis.
1 equipment enclosure having charged phenomenon
As the sound engineering equipment of all work must use electricity, so debugging may first encounter some equipment shell charged issues, although the live shell does not necessarily affect the use of equipment, but will endanger the safety of the user, must solve,
2 sound system volume inadequacy
Project commissioning is often encountered when sound volume has always been smaller, do not reach the design requirements of the phenomenon of sound pressure level, this description of equipment in the installation and settings have problems
The 3 field of resonance and feedback
Although in the design and construction have been seriously considered, but is not very thorough and unexpected places, and the occurrence of these problems will affect the normal use, should be eliminated, search order
The 4 generation of noise
Audio project encountered interference noise time very much, the reason also each are not identical, usually solve rise very troublesome, but careful analysis, from the system construction to find a cause, step by step analysis, or can be resolved.
5 lights out
In audio engineering also occurs sometimes light motor incoordination, is controlled by a controller and accidental error action, although sometimes slightly out of control will not bring much impact, but if the problem is not a long-term solution, fault is likely to further expand, at the same time the lights malfunction in performance engineering is not tolerance
The 6 video image is not normal
Professional sound engineering video transmission distance is long, usually also requires a video signal processing and distribution, give multiple display devices, intermediate link is more also, likely due to different causes of video image quality is not good, effect watching effect, so it should be processed
In 7 wireless microphone voice instability
Now the majority of audio engineering are equipped with a wireless microphone, but due to improper installation and commissioning, a considerable number of use condition, especially in live performances, radio microphone's work will directly affect the quality of performance, so, this is a problem that nots allow to ignore.
