1. Reverberation usually determines the length of the lingering sound and has a direct impact on the color and clarity of the sound. Generally speaking, when a bass sings, the reverberation time can be adjusted shorter to improve the clarity of the sound; if a soprano sings, the reverberation time can be appropriately extended to increase the color of the sound.

For singing venues, if the walls around the room are made of wooden boards, the reverberation time should be adjusted smaller to avoid the sound being blurred; conversely, if the walls around the room are made of wooden boards In this case, the reverberation time should be adjusted smaller to avoid the sound being blurred; conversely, if the room is hung with sound-absorbing materials such as velvet curtains, the reverberation time should be adjusted larger in such a room to avoid the sound being dry.

In addition, the number of spectators and listeners at the scene also has a great impact, because the audience's clothing also has a great sound-absorbing effect. Therefore, sound engineers and tuners can choose a reverberation time that feels appropriate between 1 and 2 seconds.

2. Completely direct sound without reverberation sound output will not be able to improve and beautify the sound, so it is usually only used for speeches or recitations in meetings. Appropriately increasing the proportion of reverberation components will help simulate natural reverberation, making the sound plump and pleasant, and can increase the audience's three-dimensional sense of the scene.

Completely reverberated sound without direct sound component output will cause the sound to be "colored" and cause serious distortion, that is, the sound will be as unclear as the sound heard in the bathroom or bathhouse. People in the industry call it the “bathroom effect.”

Therefore, if there are no special requirements, the knob can be adjusted to the middle position, that is, the ratio of direct sound component to reverberation sound component is 1:1. In this way, the sound will not only not be distorted, but also There will be a certain reverberation effect.

3. A good song should have accompaniment music accounting for 40% and singing voice accounting for 60%. If the singer’s voice is good, the weight of some accompaniment music can be appropriately reduced to highlight the singer’s voice. Singing: If the singer is not very familiar with the melody of the song, it is easy to sing out of tune and out of time. In order to cover up these shortcomings, the weight of some accompaniment music can be appropriately increased.

However, during specific operations, you should be careful not to increase the microphone volume too much, let alone sing at a volume much higher than the accompaniment music. The result is that the accompaniment sound is too weak, and most of the time only the singer's voice is heard, as if a person is singing a cappella, and the atmosphere of karaoke is lost; but the accompaniment sound should not be too strong, as the accompaniment sound is too strong, and it will be "drowned" "The singer's singing sounds like it's just a band playing music, and you can't understand the singer's mood.

4. The accompaniment music is played according to the tone of the original singer. It cannot adapt to the noise conditions of each singer. For example, some original singers have a higher vocal range, and some original singers have a higher vocal range. The singing range is relatively low. In order to allow the accompaniment music to take into account the noise characteristics of each singer, the sound engineer and tuner should have a sensitive auditory response to the singer's voice characteristics.

When singing, first place the tone control in the middle position. Since it does not increase, it does not decrease. At the beginning of the song, if the singer can tune up, there is no need to adjust it; on the contrary, if the singer feels that the bass range cannot sing, or the high range cannot keep up, the transmitted pitch can be adjusted to the singer's adaptability according to the actual situation.
