KTV audio system daily maintenance

A good karaoke environment is the primary condition for consumers to choose KTV, which requires the owner of the KTV to be equipped with a set of high-quality karaoke equipment, large-screen LCD TV, microphone and sound system. Then, the KTV song system, the stability of the sound system and the sound effect are particularly important. How can we make the song system and sound system stable? How can we debug the sound equipment to the best state and achieve the best results?

First of all, according to the characteristics of each KTV to develop a series of equipment maintenance and maintenance, debugging plans and institutionalization. Then, according to the established plan and system, the specific regular maintenance and maintenance work is carefully carried out. Finally, check all the work carefully, and find that there is a problem to immediately rework according to the specification. Secondly, it is necessary to train all employees in sound knowledge and daily operation.

First, talk about equipment maintenance, equipment maintenance to carry out regular planned maintenance and daily general maintenance. Planned maintenance is to carry out weekly or monthly large-scale maintenance work according to local conditions, such as dust removal, testing, and checking whether each cooling fan has aging phenomenon. Nip some glitches in the bud. Daily maintenance is the work to be done every day just go to work, the microphone, microphone line, power amplifier, workstation, speaker, song panel, etc., to carefully check the room by room, found that the fault should be repaired in time, such as the microphone line is a fragile part, often do not contact good cause silent or noise, if the inspection is not in place, no matter how good the sound, the effect can not come out. In addition, each batch of guests will be checked out once.

Let's talk about sound tuning. To do this work has a certain difficulty, but as long as the master of the method and persevere to do it, then difficult problems will be solved. Here is a look at the adjustment skills of audio equipment in KTV rooms:

(1) How to adjust the timbre

If the timbre treatment is not good, it will not only make the sound monotonous, but also cause serious distortion of the instrument or singing, so the importance of timbre treatment must not be ignored. For male voices, most people's voices are relatively low and lack high notes. In order to improve the clarity of singing, the frequency component of about 3000Hz can be appropriately improved; The female voice is mostly too high and the sound is "sharp", in order to make the sound loud and not too harsh, the frequency component of about 400Hz can generally be appropriately upgraded.

(2) How to adjust the reverberation time

Reverberation usually determines the length of the aftersound and has a direct effect on the color and clarity of the sound. Under normal circumstances, when the bass sings, the reverberation time can be adjusted to improve the clarity of the sound; If it is a soprano singing, the reverberation time can be appropriately extended to increase the color of the sound. For the singing venue, if the walls around the room are composed of wood materials, then it has a certain reverb effect, and the reverb time should be reduced to avoid a blurred sound; On the contrary, if the room is a glass structure, or there are sound absorbing materials such as flannel curtains, such a room lacks reverberation, and the reverberation time should be increased to avoid dryness of the sound. In addition, the size of the audience also has a great impact, because the audience's clothing also has a great absorption effect on the sound. Generally speaking, the tuner can choose a suitable reverberation time between 1-2 seconds.

(3) How to adjust the proportion of direct sound and reverberation sound

Appropriately increasing the proportion of reverberation weight is conducive to simulating the natural reverberation effect, making the sound full and pleasant, and increasing the three-dimensional sense of the audience and listeners. If the reverberation sound is too much and the direct sound weight is too little, it will make the sound seriously distorted, just like the sound heard in the bathroom and the bathhouse, which is the so-called "bathroom effect". Therefore, in the absence of special requirements, the reverb adjustment knob can be adjusted in the middle position, that is, the ratio of direct sound weight to reverb sound weight is 1:1. In this way, the sound will not produce distortion, but also have a certain reverb effect.
