(1) how to adjust the sound
If the sound is not handled properly, not only make the sound monotonous, but also make the instrument or concert to produce serious distortion, therefore, must not ignore the importance of sound processing. For the male voice, most people's voice is relatively low, the lack of treble, in order to improve the clarity of singing, generally about 3000Hz frequency components to upgrade; and girls and more for the treble too much sound made "sharp" , In order to make the sound loud, and will not be too harsh, generally about 400Hz frequency components to improve the appropriate.
(2) how to adjust the reverberation time
Reverb usually determines the length of the sound, the sound of the color and clarity have a direct impact. Under normal circumstances, the bass singing, the reverberation time can be adjusted to a shorter, in order to improve the clarity of the sound; if the soprano can be appropriate to extend the reverberation time to increase the color of the sound. For the concert venue, if the walls around the room is made of wood material, then it has a certain reverb effect, then reverberation time should be adjusted to avoid some vague; the other hand, if the room is glass Structure, or hung with velvet curtains and other sound-absorbing material, such a lack of reverberation of the room, the reverberation time should be transferred to some, so as not to sound dry. Also, the number of spectators also have a great impact, because the audience's clothing on the sound also has a great absorption effect. In general, the tuner can choose a suitable reverberation time between 1-2 seconds.
(3) how to adjust the proportion of direct sound and reverberation volume
Appropriate increase the proportion of reverberation volume, is conducive to simulate the natural reverberation effect, so that sound full of sound, can increase the audience and the audience of the three-dimensional scene. If the sound is too much and the amount of direct sound is too small, it will make the sound seriously distorted, like in the bathroom, the bath heard the sound as ambiguous, the so-called "bathroom effect." Therefore, in the absence of special requirements, the reverberation adjustment knob can be adjusted in the middle position, that is, direct sound volume and reverberation volume ratio of 1: 1. In this way, the sound will not produce distortion, but also a certain reverb effect.
(4) How to adjust the ratio between the microphone volume and the accompaniment volume
A good song, the amount of sense of the distribution should be roughly the accompaniment of music accounted for 40%, singing voice accounted for 60%, if the concert sound is good, may be appropriate to reduce the volume of some accompaniment music to highlight the singer's song; The singer is not very familiar with this song melody, easy to sing off, do not shoot, in order to cover up these shortcomings, this time may be appropriate to increase the number of accompaniment volume. But in operation, should be careful not to adjust the microphone volume too much, and even lost the atmosphere of karaoke OK; do not make the accompaniment is too strong, and "drowned" the singer's song.
(5) how to adjust the tone of the accompaniment music
The accompaniment is played according to the tone of the original singer, and it is impossible to adapt to the noise conditions of each singer. In order to keep the accompaniment music to the voice characteristics of each singer, the tuner should have an accurate judgment of the singer's voice characteristics. Singing, the first tone control on the middle position, neither ascending nor descending. If the singer does not have to adjust it, the singer will not be able to keep the bass, or the treble area can not keep up, according to the actual situation will adjust the accompaniment tone to the singer to adapt to the tone Area.
