Many sound engineers and tuners often feel difficult to operate when they are faced with the dazzling sound equipment. Here are some tuning skills, which are essential for learning professional amplifier knowledge.
The human ear is sensitive to timbre, it can directly distinguish whether the voice is realistic or not. If the tone color processing is not good, it will not only make the sound monotonous and boring, but also make the musical instrument or singing a serious distortion, so it is not to ignore the importance of the tone color processing. For the male voice, most people's voice is low, lack of high tone, in order to improve the articulation of the singing, the frequency of 3kHz can generally be compensated; for women's voice, the soprano appears too much and the sound is "sharp". In order to make the sound bright and not too harsh, it can generally compensate the frequency component of the 400Hz.
How to adjust the reverberation time
Reverberation usually determines the length of the remaining sound, which has a direct effect on the color and clarity of the voice. In general, when the bass is sung, the reverberation time can be adjusted to a short time to improve the clarity of the sound. If the soprano is sung, the reverberation time can be extended to increase the color of the sound. For a concert place, if the walls of the room are made up of board material, the reverberation time should be reduced to avoid blurring; conversely, if the walls of the room are made up of board materials, the reverberation time should be smaller, and the sound is blurred; conversely, if the room is hung up. There are sound absorbing materials such as flannelette curtains, such rooms should be reverberation time larger, so as to avoid the sound dry. In addition, the number of spectators and listeners also has a great impact, because the clothing of the audience also has a great absorption effect. Therefore, the sound engineer and the tuner can choose a suitable reverberation time in 1~2 seconds.
How to adjust the ratio of direct to reverberation and reverberation sound components
The direct output of sound without reverberation can not improve and beautify the voice, so it is usually used only for occasions where speaking or reciting. Appropriately increasing the proportion of reverberation sound is conducive to simulating natural mixing sound, making the sound sound and pleasant, and increasing the audience's stereo feeling. Complete reverberation and no direct sound output will cause the sound to produce "dyed" phenomenon, causing serious distortion, that is to say, as vague as the sound heard in the bathroom, in the bathhouse, it is called the "bathroom effect". Therefore, in the case of no special requirement, the knob can be adjusted in the middle position, that is, the proportion of the direct sound component and the reverberation sound component is 1:1, so that the sound will not only produce no distortion, but also have certain reverberation effect.
How to adjust the ratio between microphone volume and accompaniment music
A sound song should be 40% of accompaniment music and 60% for singing. If the singer has a good tone, it can appropriately reduce the components of some accompaniment music to highlight the singer's song; if the singer is not very familiar with the melody of the song, it is easy to sing the tune, not to be shot, in order to disguise these shortcomings, The components of some accompaniment music can be properly increased. But in the specific operation, we should pay attention not to overturn the microphone volume, but not to sing the volume much higher than the accompaniment music. The accompaniment was too weak to hear the voice of the singer for most of the time, as if a person had been singing there and lost the atmosphere of Cara's OK; but he could not make the accompaniment too strong, too strong, and "drown" the singer's singing, as if only a band was playing music and no singers could understand. The interest of the person.
How to adjust the tone of accompaniment music
Accompaniment music is played according to the tone of the singer. It can not adapt to the noise conditions of every singer, for example, some of the singers have a high pitch, and some of the singers sing in the sound area is low. In order to allow accompaniment music to take care of the noise of each singer, the acoustics and the vocalist should respond to the singer. The sound characteristics are sensitive to the auditory response. When singing, put the tone control in the middle position. If it is not promoted, it will not drop. At the beginning of a song, if the singer is up and up, it does not need to be adjusted; on the other hand, the singer can not go down in the bass area or the soprano area can not follow, and the tone can be adjusted to the vocal area adapted to the singer according to the actual situation.
Tuning is a very artistic operation process. It needs the tuner to have a good sense of music and understanding. It needs to have high musical accomplishment at ordinary times and have a sensitive hearing reaction to the scene. So the voice can be accepted by the audience.
