[Technology] Karaoke sound system adjustment skills

The difference between karaoke sound and general home theater audio is that as a device to restore human voice, the K song effect will be affected by the speaker, so the speaker is required to have sufficient power in addition to excellent sound quality. If the sound quality of the speaker is not good or the power is not enough, the sound will be distorted in the K song, so the fun of the K song is greatly reduced, so a pair of powerful speakers is necessary. Some users tend to spend a lot of money on speakers and amplifiers, and they are very embarrassed in terms of microphones. This is really regrettable. The microphone is the key equipment in karaoke. If the microphone is not properly selected, the whole effect will not be discussed. Imagine that the song is dull, thin, distorted, easy to whistle, where is the enjoyment? So in the karaoke system, the choice of the microphone can not be sloppy. A heart-shaped, super-cardiac dynamic microphone should be selected.

Don't be afraid of it, use it to understand that the sound effect is different. Of course, the adjustment of the equipment is equally important. Please see the operation adjustment of the karaoke system below.
Adjust the tone

If the tone is not handled well, it will not only make the sound monotonous, but also cause serious distortion of the instrument or the singing. Therefore, the importance of the tone processing must not be ignored. For male voices, most people's voices are relatively low, lacking high-pitched sounds. In order to improve the clarity of singing, it is generally possible to properly raise the frequency components around 3000 Hz; while female voices are mostly high-pitched sounds, making the sound "tip" In order to make the sound loud and not too harsh, the frequency component around 400Hz can be appropriately upgraded.

Adjust the reverberation time

Reverb usually determines the length of the reverberation and has a direct impact on the color and clarity of the sound. Under normal circumstances, when the bass is singing, the reverberation time can be shortened to improve the clarity of the sound; if the soprano is singing, the reverberation time can be extended appropriately to increase the color of the sound. For the singing place, if the wall around the room is made of wood material, then it has a certain reverberation effect, then the reverberation time should be reduced to avoid blurring the sound; otherwise, if the room is glass Structure, or sound-absorbing materials such as flannel curtains, such a room lacks reverberation, the reverberation time should be increased to avoid dryness. Also, the number of live audiences has a great impact, because the audience's clothing also has a great absorption of sound. In general, the tuner can choose a suitable reverberation time in 1-2 seconds.

Adjust the proportion of direct sound and reverb sound

Appropriately increasing the proportion of reverberation sounds is conducive to simulating the natural reverberation effect, making the sound full and beautiful, which can increase the stereoscopic feeling of the audience and the audience. If there are too many reverberations and too few direct sounds, the sound will be seriously distorted, just like the sound heard in the bathroom and bathhouse, the so-called "bathroom effect." Therefore, in the case of no special requirements, the reverberation adjustment knob can be adjusted to the middle position, that is, the ratio of the direct sound amount to the reverb sound volume is 1:1. In this way, the sound will not produce distortion, but also has a certain reverberation effect.

Adjust the ratio between the microphone volume and the accompaniment volume

A good song, in terms of volume distribution, should be about 40% of the accompaniment music and 60% of the singing sound. If the singer sounds good, the volume of some accompaniment music can be appropriately reduced to highlight the singer's singing voice; The singer is not very familiar with the melody of this song, and it is easy to sing and turn off the beat. In order to cover up these shortcomings, some accompaniment volume can be appropriately increased. However, in operation, care should be taken not to excessively adjust the volume of the microphone to lose the karaoke atmosphere; nor to make the accompaniment too strong, and to "submerge" the singer's voice.

Adjust the pitch of the accompaniment music

The accompaniment music is played according to the tone of the original singer, and it is impossible to adapt to the noise conditions of each singer. In order to allow the accompaniment music to take care of the vocal characteristics of each singer, the tuners should have an accurate judgment of the singer's voice characteristics. When singing, first put the tone control in the middle position, neither raising nor falling. At the beginning of the song, if the singer gets up, it doesn't have to adjust it. If the singer feels that the bass zone can't sing, or the high-pitched area can't keep up, adjust the accompaniment tone to the singer's adapted sound zone according to the actual situation.

In short, when using the karaoke system K song, the tone is beautiful and the sense of presence is strong. With high-definition high-frequency extension, high-frequency fiber is complete, bright and not hairy; the intermediate frequency is very smooth and comfortable, the sound is bright, round and sweet; the low frequency is strong, and the dive is deep, you can configure the subwoofer to make the low frequency enough. Let the body feel the shock of the heavy bass!

Solar Water Heating System

Solar water heating system is a cost-effective system for residential hot water application. This system is designed according to thermosiphon principle and operating with proportion difference between cold and hot water. The water heated by vacuum tubes is held in the stainless steel storage tank where the insulation preserves the heat.

The thermosiphon Solar Water Heater uses the sun to heat the working fluid (mostly water) in the Vacuum Tubes. The Solar Collector absorbs solar radiation, and converts the sunlight to heat and transfer it to the water. The heated water naturally rises through the solar collector into the water tank where the cooler water at the bottom of the tank is forced out and descends to the bottom of the collector (thermosiphon circulation). The circulation will be interrupted when there is no solar radiation.
