The ear feels very sensitive to the sound, it can directly feel whether the sound is realistic. If the tone is not deal well, it wont only make the sound monotonous, boring, but also cause serious distortion to instrument or the singing, so cant ignored tone processing. For male voices, most man's voices are relatively low, lacking high-pitched sounds. In order to improve the clarity of singing, it is generally to compensate 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 Echo Time

Usually Reverb determines the length of the reverberation and has a direct impact on the clarity of the sound. Usually, when bass singing,  in order to improve the clarity of the sound make reverberation time ; if soprano singing, in order to increase the color of the sound to make  reverberation time extended

For the singing place, if the wall is made of wood material, then the reverberation time should be reduced to avoid sound blurring; otherwise, if the room is covered with sound absorbing materials such as flannel curtains, the reverberation time should be long to prevent the sound from drying up. In addition, More or less viewers also has a great impact,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’t improve the beautify of the sound, it is usually only used for meetings or readings. 

In order increase the audience stereoscopic and feeling to add the proportion of the reverberant sound component to simulating the natural reverberation sound.and also make sound full and pleasant.Full reverberation without direct sound component output will cause the sound “stain” and serious distortion, it is as confusing

like sound heard in the bathroom or bathhouse, it is called “bathroom effect". Therefore, in the absence of special requirements, adjusted the knob to the middle position, then the direct sound component and the reverberation sound component ratio is 1:1, then 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 include music accounted for 40%, voice accounted for 60%, if the singer sounds good, you can reduce some accompaniment music to highlight the singer's voice; if the singer to  is not very familiar to this song melody and easy to sing out of tune, not to shoot, in order to cover up these shortcomings,you can appropriately increase some accompaniment music. However, in the specific operation, take care on the microphone volume not too large, and not to make sing the volume much higher than the accompaniment music.

The result is that the accompaniment sound is too weak. Most of the time, only hear the singer's voice . It seems that only a person singing there and loses the atmosphere of karaoke. But if the accompaniment sound is too strong, the singer’s voice will be "submerged.by the sound is too strong, and", it sounds like a band is playing music, and can't feel the singer's taste."

How to adjust the tune 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 vocal range. In order to make accompaniment music match   each singer noise characteristics , 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 nether improve nor fall.  if the singer match the tune At the beginning of the song, it doesn't need adjusted. On the contrary, if the singer match the bass zone tune, or the high-pitched tune, according to the actual situation to adjust Sound zone.

Tuning is an strong artistically operation process. It requires the tuner have a good sense of music and savvy. also requires a high level of musical cultivation and a sensitive auditory response to the scene.
