Common audio engineering problems

Analysis of the problems existing in sound engineering

We want to "remedy the symptoms", we first look at the many audio engineering problems in the "commonality". According to the characteristics of sound engineering, a lot of sound problems generally do not appear in the construction process, many times, sound problems appear in the debugging stage of sound equipment, or sound equipment installation for a period of time, there will be many small problems. Sometimes, some of the existing sound faults disappear somehow, but do not know when this will happen again. I believe that many sound engineers are "empathize" with this kind of experience. So there are various forms of these minor problems, but as long as you ensure that the sound design is not a problem, then the root cause of these failures is only one, that is, the sound engineering construction link has a minor omission.

Two. The 8 most common problems in professional audio engineering.

Lighting out of control

Sometimes in sound engineering, the movement of light is not coordinated, uncontrolled or wrong. Although slight light runaway will not affect normal operation, if the problem is not solved for a long time, then this small fault is likely to turn into a major fault. Moreover, no performance will tolerate the phenomenon of light out of control.

The enclosure of audio equipment is electrified.

The operation of sound engineering must use electricity, so in the debugging of sound equipment, the problem of electrified sound equipment shell often appears. Although this is not a big problem, but in serious cases will endanger the safety of staff, which can not be ignored.

Video and image display is abnormal.

Video transmission distance in professional audio engineering is generally longer. Usually the signal needs to be processed and distributed by video, and then given to a number of display devices. There are also many links in the middle. The video image quality may be poor due to different reasons, affecting the viewing effect, so it should be processed.

Resonance and feedback in the sound field.

Although the sound engineering design and construction have been carefully considered, but inevitably there are not too comprehensive and unpredictable, and this problem certainly affects the normal use of people, should be eliminated.

The voice of wireless microphone is unstable.

At present, most of the sound engineering equipped with wireless microphones, but due to improper installation and debugging, a considerable number of poor use, especially in the performance scene, wireless microphone work will directly affect the quality of the performance, so this is a problem that can not be ignored.

Sound system is not enough.

Sound engineering debugging often encounters the phenomenon that the volume of the sound is always small, which can not meet the requirements of the design sound pressure level, which shows that the equipment has problems in installation and installation.

Interference noise

Sound engineering encountered a lot of interference noise time, the causes are also different, usually very troublesome to solve, but as long as careful analysis, from the construction of the system to find the reasons, step by step analysis, the problem can always be solved.

The bulb of a computer lamp is often damaged.

Although the damage of the bulb is a normal phenomenon, but if the use of a very short period of time to damage, it should not be a normal phenomenon, especially the computer lamp bulb is generally more expensive, often replaced will increase the cost of less, the quality of the computer bulb life should generally be more than 750 hours, if not strong Due to the failure of solid and durable operation, the bulb will be damaged and the use time should be lower than this requirement.
