Getting Started with Tuning Techniques.Audio equipment bar Processor

　　Many sound engineers and tuners often find it difficult to operate when faced with a dazzling array of audio equipment. The following introduces some tuning operation skills, which are also essential for learning professional power amplifier knowledge.

　　The human ear is more sensitive to timbre, and it can directly determine whether the sound is realistic or not. If the timbre is not handled well, it will not only make the sound monotonous and boring, but also cause serious distortion of the musical instrument or singing. Therefore, the importance of timbre processing cannot be ignored. For male voices, most people's voices are relatively low and lack treble. In order to improve the clarity of singing, the frequency of 3kHz can generally be compensated. For female voices, the treble is too much, and the sound is "sharp" In order to make the sound louder and not too harsh, the 400Hz frequency component can generally be compensated.

　　How to adjust the reverberation time

　　Reverberation usually determines the length of the reverberation, which 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 it is a soprano singing, the reverberation time can be appropriately extended to increase the color of the sound. For a concert venue, if the walls around the room are made of wood, the reverberation time should be reduced to avoid blurring the sound; on the contrary, if the walls around the room are made of wood, the reverberation time should be reduced. The time should be reduced to avoid blurring the sound; on the contrary, if the room is hung with sound-absorbing materials such as flannel curtains, the reverberation time should be increased in such a room to avoid dry sound. In addition, the size of the audience and the audience also has a great impact, because the audience's clothing also has a great sound absorption effect. Therefore, sound engineers and tuners can choose a reverberation time that feels appropriate between 1 and 2 seconds.

　　How to adjust the proportion of direct sound and reverberation sound components

　　Full direct sound without reverberation output cannot improve and beautify the sound, so it is usually only used for speeches or recitations in meetings. Appropriately increasing the proportion of reverberation sound components is conducive to simulating natural reverberation sound, making the sound plump and pleasant, and increasing the audience's three-dimensional sense of the audience. Fully reverberated sound without direct sound component output will cause the sound to "color" and cause severe distortion, that is to say, the sound is as ambiguous as the sound heard in the bathroom or bathhouse, which is called "bathroom" by people in the industry. effect". Therefore, if there are no special requirements, the knob can be adjusted to the middle position, that is, the ratio of the direct sound component to the reverberated sound component is 1:1, so that the sound will not only be distorted, but also have a certain reverberation effect. .

　　How to adjust the pitch of the accompaniment music

　　The accompaniment music is played according to the tone of the original singer, and it cannot adapt to the noise conditions of each singer. Let the accompaniment music take care of the noise characteristics of each singer, and the sound engineer and tuner should have a sensitive auditory response to the vocal characteristics of the singer. When singing, first put the pitch control in the middle position, since it does not increase, it does not decrease. At the beginning of a song, if the singer can tune up, there is no need to adjust it; on the contrary, if the singer feels that the low-pitched area cannot keep up, or the high-pitched area cannot keep up, he can adjust the transmission tone according to the actual situation. sound area.

　　Tuning is a very artistic operation process. It requires the tuner to have a good sense of music and understanding, to have a high level of music training, and to have a sensitive auditory response to the scene, so that the sound can be tuned. accepted by the audience.

　　How to adjust the ratio between microphone volume and accompaniment music

　　For a good song, the accompaniment music should account for 40% and the singing voice should account for 60%. If the singer's tone is good, the weight of some accompaniment music can be appropriately reduced to highlight the singer's singing voice; You're not very familiar with the melody, it's easy to sing out of tune, and it doesn't match the beat. In order to cover up these shortcomings, you can appropriately increase the weight of some accompaniment music at this time. But in the specific operation, you should be careful not to increase the volume of the microphone too much, let alone the volume of singing is much higher than the accompaniment music. As a result, the accompaniment sound is too weak, and only the singer's voice is heard most of the time, as if a person sings a cappella there, losing the atmosphere of karaoke; but the accompaniment sound cannot be made too strong, and the accompaniment sound is too strong, and it will "drown out". "The singer's voice sounds like it's just a band playing music, and you can't understand the singer's taste.
