Many sound engineers and tuners often find it difficult to operate when faced with a wide range of audio equipment. Here are some tuning techniques that are essential to learning professional amp knowledge.
The human ear is more sensitive to the sound, it can directly determine whether the sound is realistic. If the tone is not handled well, it will not only make the sound monotonous, boring, but also cause serious distortion of the instrument or the singing, so the importance of the tone processing cannot 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 compensate for the frequency of 3 kHz. For female voices, the treble is too much, and the sound is "tip". In order to make the sound loud and not too harsh, the 400Hz frequency component can generally be compensated.
How to 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 the reverberation time should be reduced to avoid blurring the sound; otherwise, if the wall around the room is made of wood material, then the reverberation The time should be smaller, and the sound should be blurred by name; on the contrary, if the room is covered with sound absorbing materials such as flannel curtains, the room should be adjusted to a larger reverberation time to prevent the sound from drying up. 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. Therefore, the sound engineer and the tuner can choose a suitable reverberation time in 1~2 seconds.
How to adjust the proportion of direct and reverberant components
Full direct sound without reverberant sound output can not improve and beautify the sound, so it is usually only used for meetings or readings. Appropriately increasing the proportion of reverberant sound components is conducive to simulating the natural reverberation sound, making the sound full and pleasant, which can increase the stereoscopic feeling of the audience and the audience. Full reverberation without direct sound component output will cause the sound to “stain” and cause serious distortion, that is, it is as confusing as the sound heard in the bathroom and bathhouse, and the people in the line call it “bathroom”. effect". Therefore, in the absence of special requirements, the knob can be adjusted to the middle position, that is, the direct sound component and the reverberation sound component ratio is 1:1, so that the sound will not only produce distortion, but also have a certain reverberation effect. .
How to adjust the ratio between the microphone volume and the accompaniment music
A good song, should be accompaniment music accounted for 40%, singing voice accounted for 60%, if the singer sound is good, you can appropriately reduce the weight of some accompaniment music to highlight the singer's song; if the singer to this song The melody is not very familiar, it is easy to sing the tune, not to shoot, in order to cover up these shortcomings, then you can appropriately increase the weight of some accompaniment music. However, in the specific operation, care should be taken not to make the microphone volume too large, and not to sing the volume much higher than the accompaniment music. The result is that the accompaniment sound is too weak. Most of the time, only the singer's voice is heard. It is like a person singing there and losing the atmosphere of karaoke. But the accompaniment sound is too strong, the sound is too strong, and it will be "submerged." "The singer's voice, it sounds like a band is playing a piece of music, and can't appreciate the singer's taste."
How to adjust the pitch of the accompaniment music
The accompaniment music is played according to the tone of the original singer. It can't adapt to the noise conditions of each singer. For example, some original singers have higher vocal range, and some original singers sing lower pitches. Let the accompaniment music take care of the noise characteristics of each singer, the sound engineer and the tuner should have a sensitive auditory response to the singer's voice characteristics. When singing, first put the tone control in the middle position, since it does not improve, it does not fall. At the beginning of the song, if the singer gets up, it doesn't have to be adjusted. On the contrary, if the singer feels that the bass zone can't sing, or the high-pitched area can't keep up, the tone can be adjusted to the singer's adaptation according to the actual situation. Sound zone.
Tuning is an artistically strong operation process. It requires the tuner to have a good sense of music and savvy. It is necessary to have a high level of musical cultivation and a sensitive auditory response to the scene. Accepted by the audience.
