Eight difficult problems that should be dealt with immediately in professional sound engineering

KTV, karaoke bars, bars, discos and other nights are inseparable from sound engineering. When installing audio equipment, we often encounter some problems. The types and quantity of audio lighting systems are relatively large, and the audio technical requirements are also very large. Differences, so when installing audio equipment, various problems are inevitable. Below we analyze the eight most common problems in professional audio engineering for everyone, I hope to help you install audio equipment!

I. Characteristic analysis of problems existing in sound engineering

We want to "prescribe the right medicine". Let us first look at the "commonness" of the problems in many sound engineering. According to the characteristics of sound engineering, many audio problems generally do not appear in the construction process. In many cases, the audio problems often appear in the debugging stage of the audio equipment, or after the audio equipment is installed for a period of time, there will be many small problems. Sometimes, some of the sound failures that existed will disappear inexplicably, but I don't know when this will happen. For such an encounter, I believe that many sound engineers have a little "feeling". Then these small problems appear in various forms, but as long as you ensure that the sound design is no problem, then there is only one source of these faults, that is, there are small omissions in the sound engineering construction.

Second, the most common 8 difficult problems in professional audio engineering analysis

1, the light out of control phenomenon

In sound engineering, there is sometimes a phenomenon in which the lighting movement is uncoordinated, uncontrolled or malfunctioning. Although a slight out of control of the light will not affect normal operation, if the problem is not resolved for a long time, then the glitch is likely to be converted into a large fault. Moreover, any performance will not tolerate the phenomenon of out of control of the lights.

2. The charging of the outer casing of the audio equipment

The operation of sound engineering must use electricity, so when the audio equipment is debugged, the problem of charging the audio equipment casing often occurs. Although this is not a big problem, it will endanger the safety of the staff in serious cases, which cannot be ignored.

3, the video image display is not normal

The video transmission distance in professional audio engineering is generally long. Usually, the signal needs to be processed and distributed by video, and then given to multiple display devices. There are many links in the middle, which may result in poor video image quality due to different reasons. Affects the viewing effect, so it should be processed.

4. Resonance and feedback occur in the sound field

Although serious considerations have been made in the design and construction of sound engineering, it is inevitable that there are places that are not comprehensive and unpredictable, and the occurrence of this problem is definitely affecting normal use and should be eliminated.

5, wireless microphone sound is unstable

Most audio projects are now equipped with wireless microphones, but due to improper installation and debugging, there are a considerable number of poor use conditions, especially at the performance site, the work of wireless microphones will directly affect the quality of the performance, so this is not allowed Neglected problems.

6, the sound system is not enough volume

When the sound engineering is debugged, the volume of the sound is always small, which does not meet the requirements of the design sound pressure level. This indicates that the equipment has problems in installation and setting.

7, generating interference noise

There are many times when there are interference noises in the sound engineering, and the causes are different. Usually it is very troublesome to solve, but as long as you carefully analyze it, find the cause from the construction of the system and analyze it step by step. The problem can always be solved.

8, the light bulb of the computer light is often damaged

Although the damage of the bulb is normal, if it is damaged for a short period of time, it should not be normal. In particular, the price of the bulb of the computer lamp is generally more expensive. Frequent replacement will increase the overhead and the quality is better. The life of a computer light bulb should generally be more than 750 hours. If it is not strong and durable, the bulb will be damaged. If the usage time is lower than this requirement, it should be searched.
