【 Weak current College 】 professional audio engineering problems

As a complex, technical types of projects carried out in sound engineering in a variety of problems that may occur, together with the acoustic light system types and quantity of equipment, and systems technical requirements also vary, so all kinds of problems are inevitable, often encounter some knotty problems. According to the characteristics of sound engineering, engineering design to project quality and progress play a major role, so as long as the construction design and carefully follow the relevant specification, is generally not in the construction process have any problems, or that these problems will not be reflected in the construction. In most of the time, the engineering problems occur during the commissioning phase, or even use only after a certain period of time.

Since it is a hard problem to solve is very easy, and often is the fee to check exhaustively for a long time, always persists; in later questions puzzling ourselves disappear, then I do not know when it happens, get people very headache, each engaged in sound engineering technical work will have varying degrees of experience. But while these problems is the variety of forms, but as long as the design has no errors, you can say there is only one of the roots, that is; construction of omissions. Therefore, even if they're difficult problems, or can be solved.

The following is a common part of typical problems.

(1) the device shell has charged phenomenon due to sound engineering work on all devices must use electricity, so debugging may first encounter part device shell live, although shell live does not necessarily affect the use of the device, but will endanger the safety of users, you must resolve.

(2) audio system volume is insufficient project debugging when audio volume is always smaller and not reach the design of the sound pressure level requirement, it just goes to show devices in installation and Setup problems.

(3) acoustic resonance and feedback occurs while in the design and construction is seriously considered, but inevitably there are not too comprehensive and unpredictable places, and that this problem will certainly influence the normal use, should be removed.

(4) produce interference noise audio engineering experience interference noise a lot of time, cause vary, usually solving very trouble, but as long as serious analysis, from the system of construction is found on the analysis of the causes, gradually, the problem is resolved.

(5) lights out in audio engineering and sometimes people occur lights motion does not coordinate, it shall not be subject to the control and the occasional mistakes, etc., although slightly out of control will not lead to great effect, but if the problem is not resolved a long time, the fault may be further expanded, while the lights of the malfunction in the performance of works not be tolerated.

(6) PC lamp bulb often damaged while the lamp damage is normal, but if you use time is very short on corruption should not be is normal, especially computer lamp bulb prices generally more expensive, often replace will increase less overhead, better quality of life of the computer lamp generally should be 750 hours, if not durable operation failures cause the bulb to damage, use time below this requirement should be to find it.

(7) video images not normal professional audio engineering video transmission distance is generally longer, usually signal will also need a video processing and distribution, and to more than one display device, the intermediate links also comparing multiple, possibly due to different reasons the video image quality is not good, affect viewing, so you should be processed.

(8) wireless microphone sounds unstable now most sound engineering is equipped with a wireless microphone, but due to improper installation and debugging, a considerable amount of usage, especially in the performance, wireless microphone work will directly affect the quality of the performance, so this is a problem.
