　　2. How to adjust the microphone?

　　At present, the dynamic microphone speakers used in popular and popular singing should be placed as far as possible not to cover the microphone pickup area. If the singing is lack of confidence, add mid-to-high frequency to emphasize his brightness. The confidence is very strong to reduce the low frequency to save the voice from breaking. Women add low frequency to thicker, men add high frequency to transparent.

　　①The equipment's turn-on and turn-off sequence

　　From audio source equipment (CD player, DVD player,), audio processing equipment (effects, etc.) to power amplifier to TV, projector. The sequence is reversed when shutting down, and the power amplifier should be turned off first. This operation can prevent the impact of turning on and off the device, and prevent the power amplifier and speakers from being burned.

　　A. The volume of the power amplifier [microphone (including fine-tuning), music] potentiometer is adjusted to the appropriate position.

　　B. The sound quality compensation knobs are all placed in the middle position.

　　C. First try the microphone sensitivity and dynamic performance, and then add reverberation and accompaniment music to sing. After reverberation processing, the singing voice should be more mellow, fuller and layered than the original song, and full of liveness.

　　D. Test accompaniment music: turn on the accompaniment music to the normal working volume; but pay attention to the volume is moderately pleasing, too loud and easy to make people tired and unbearable. (The tuner should listen to the effect in different positions. For example, the stereo sound image, sound quality, etc., the repertoire should be familiar to them). The requirements for musical effects should be dynamic and aesthetic. The treble should not be harsh, the bass should not be muddy, and the singing voice should be clear. For example, the teeth of a female voice should be clear and audible, but not too heavy.
