Many sound engineers and mixers often find it difficult to operate in the face of a dazzling array of audio equipment. Here are some tuning tips that are necessary to learn professional amplifier knowledge.
The human ear is more sensitive to timbres, and it can directly determine whether the sound is realistic. If sound processing is not good, it will not only make the sound monotonous, boring, but also people will make the instrument or singing a serious distortion, so the importance of sound processing can not be ignored. For male voices, most people have low voices and lack treble. In order to improve the clarity of singing, they can generally compensate for the frequency of 3 kHz. For female voices, the treble appears too much, and the sound is “sharp”. In order to make the sound loud and loud, it would not be too harsh. Generally, the 400Hz frequency component can be compensated.
How to adjust the reverberation time
Reverb usually determines the length of the reverberation, which has a direct effect on the color and clarity of the sound. Under normal circumstances, when the bass concert, you can adjust the reverberation time shorter to improve the clarity of the sound; if it is the soprano singing, you can extend the reverberation time to increase the color of the sound. For singing venues, if the walls around the room are made of wood material, the reverberation time should be reduced to avoid obscuring the sound; otherwise, if the walls around the room are made of wood, the reverberation The time should be reduced and the name should not be obscured. If, on the other hand, sound-absorbing materials such as flannel curtains are hung in the room, the reverberation time should be increased in such rooms to avoid sound drying. In addition, the audience of the audience and the audience also have a great influence, because the audience's clothing also has a great sound absorption. Therefore, the sound engineer and tuner can choose a suitable reverberation time between 1 and 2 seconds.
How to adjust the proportion of direct sound and reverb sound components
Fully direct sound without reverberant sound output, can not play a role in improving and beautifying the sound, so it is usually only used for meetings to speak or recite occasions. Properly increasing the proportion of reverberant sound components is conducive to simulating natural reverberation sounds, making the sound full and pleasant, which can increase the audience's and the audience's three-dimensional scene. Full reverb sound without direct sound component output will cause the sound to have a "dyeing" phenomenon, causing serious distortion, that is, as the sound heard in the bathroom, the bathhouse is so vague, the person in the line called it "the bathroom effect". Therefore, in the absence of special requirements, the knob can be adjusted in the middle position, that is, the ratio of the direct sound component to the reverberation sound component 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 microphone volume and accompaniment music
A good song should include 40% of the accompaniment music and 60% of the vocal music. If the singer's timbre is good, the amount of some accompaniment music may be appropriately reduced to highlight the singer's singing voice; if the singer The melody is not very familiar, and it is easy to sing and go out of tune. In order to cover up these shortcomings, the weight of some accompaniment music can be appropriately increased. However, in the specific operation, care should be taken not to overmodulate the volume of the microphone, and it is even more difficult to sing louder than the accompaniment. The result is that the accompaniment sound is too weak. Most of the time, only the singer's voice is heard. It is as if a person sings there and loses the karaoke atmosphere. But it cannot make the accompaniment sound too strong and the sound is too strong. "The singer's song sounds like it's just a band playing a piece of music that doesn't feel like a singer.
How to adjust the tone of accompaniment music
Accompaniment music is played according to the tone of the original singer. It cannot be adapted to the noise conditions of each singer. For example, the vocal range of some singers is relatively high, and the vocal area of some singers is relatively low. Let the accompaniment music take care of the noise characteristics of each singer. The sound engineer and the tuner have a sensitive hearing 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 a song, if the singer is adjusted upwards, then there is no need to adjust; on the other hand, if the singer feels that the bass zone cannot sing or the treble zone cannot keep up, the transmission tone can be adjusted to the singer's adaptation according to the actual situation. Sound zone.
Tuning is a very artistic operation process. It requires the tuner to have a good sense of music and understanding. It requires a high level of musical training and a sensitive auditory response to the scene. It was accepted by the audience.
