The so-called tuning of stage sound is divided into two parts, one is mainly for the signal characteristics of various signal sources, adjust the feeling required by people, and control the timbre of the signal source through balanced adjustment to meet the requirements of individuals or programs. The second is the volume coordination between multiple voices to control the proportion. The first step of tuning is to control the signal level input by the signal source equipment to the mixer, and adjust each signal to about 0dB through the gain GAIN knob with the level meter, which is a very critical step and will directly affect the quality of the signal. The gain is too high, easy to distort, the gain is too low, the signal-to-noise ratio is reduced, this step is not well controlled, and the subsequent work has all become a castle in the air.

 

After controlling the input level, the tone of each signal should be adjusted by an equalizer to meet the requirements. In general, the control of microphones, instruments, or finished program sources. It should be noted that the balance on the mixer is a tuning weapon, don't just think of adding equalization to the system to deal with the timbre, and rationally use the balance of the mixer to achieve the goal of tuning.

 

Tuning of the microphone

 

The stage sound is mainly for the frequency response characteristic defects of the microphone itself or the voice characteristics of the singer to make balanced compensation, and carry out artistic modification on the basis of improving the degree of reduction. To master this step, the tuner must first have an understanding of the voice, for example, if you hear the voice of a singer, you know where the flaws and strengths of his voice are. Or take a microphone and you can tell in which band the microphone is prominent or lacking. Only by correctly recognizing the defects of the singer's voice or the microphone itself, you can make targeted adjustments, and the frequency sweep function of the mixer equalization allows you to select and process the frequency band for the frequency response defects you find. It should be noted that if you install your own preferences to bring up a microphone effect that you are satisfied with, it often does not necessarily meet the requirements of the singer, after all, it is he who sings on stage instead of you singing on stage.

 

Tuning of stage sound instruments

You need to have a deeper understanding of the sound and timbre of the instrument, listen to the sound of the instrument before the movement equalization, you need to be able to find that there is a problem with the sound, and then adjust it. For example, what kind of sound should be an electric guitar, you should have a correct impression in your mind, when actually tuning, you take the impression in your brain to compare the sounds heard on the spot, feel the difference between them, and then adjust the balance, so that the sound heard by the ears matches the impression in your brain. If you don't have the impression of the sound of the instrument in your mind, then strengthen listening training, listen to the performance of real instruments, such as JAZZ, etc., over time, you will have an understanding of the sound of the instrument. When I don't understand the sound of the instrument, the tuning of the instrument becomes a blind tune.

Acoustic characteristics must not only meet the requirements of the national standard for acoustic characteristic indicators, but also meet the requirements of subjective listening, because acoustic characteristics indicators cannot fully reflect the actual sound effect, and the quality of sound is determined by people's subjective listening feelings.

In the stage sound system and large stage lighting concert venue, a very important part of the human voice is the reverb processing. The human voice after reverb processing, can produce a kind of electronic acoustic beauty, so that the song has a special flavor. It can be some amateur singers voice in the existence of certain defects, such as hoarse, throaty and sharp noise of the vocal folds of the murmur after reverb processing to mask, so that the sound is not so difficult to hear. In addition, reverb can also make up for amateur singers due to the lack of specialized vocal training and produce the phenomenon of overtones in the structure of the tone is not rich. This is very important to the effect of stage lighting concerts held.
