The KTV audio system debugging should adjust the sound quality and volume. Due to the KTV singing karaoke, the voice quality of the person who has not been trained is not pure and lacking brightness. The male voice is prone to laryngeal sound and hoarse, and the female voice is prone to breathless noise and defective sound. Therefore, it is necessary to remove the high frequency 500MHz or more, and it is also necessary to remove the low frequency 100Hz below 100Hz. At the same time, increase the 3-6dB in the mid-frequency band to increase the brightness to make the sound clear and bright. Generally, the singer's sound is low and lacks loudness, so the volume should be as much as possible, and the frequency segment near 2000MHz can be increased, so that the processing can also increase the sound sound.

The KTV audio system debugging must adjust the ratio of microphone volume to accompaniment volume again. Generally speaking, a nice song, in terms of a sense of quantity, should be roughly 40%of accompaniment music and 60%of the singing sound. If the singer is not familiar with the melody of the song, it is easy to sing away, and it cannot be filmed, then some accompaniment volume KTV audio system can be appropriately increased to beautify the sound. The characteristics of KTV singing is to add electronic sounds to the singing, which can cover up some defects in the voice and sound. When a man is singing, it can generally be shortened by the reverberation time, while the female tweeter singing can be appropriately prolonged to increase the color of the sound. As for the singing environment, if the walls around the room are made of wooden boards, it itself will have a reverberation effect. At this time, the reverberation time should be shortened to avoid blurring the sound; if there is no special requirements, you can mix it. The ratio of the ring knot knobs is adjusted in the middle, that is, the ratio of direct sound and reverberation components is roughly debug the KTV audio system -the tuning of the KTV private room audio howling.
