Nowadays, singing K has become one of the ways for people to entertain and entertain. The competition in the industry is fierce. Therefore, it is necessary to improve the service level and quality, so that enterprises can be neutral and invincible in the same industry. Then, the stability and sound effects of the KTV sound system are particularly important.

KTV sound system wants to achieve good results when using, the specific operation adjustment is also very important, the following points for the following operations adjustment points:

1. Inspire, guide, and teach. People go to entertainment venues with professional audio entertainment and entertainment, in addition to tea and wine, but also personally sing. But most people are not professional singers, have no basic training, lack singing skills, and don't use microphones. Therefore, we should first eliminate the concerns and dare to let go of the singer. At the same time, learn to operate the microphone. For example, the general song can be picked up by the middle distance, and the microphone is about 20cm away from the singer. If it is a lyrical song or a soft vocal singing, the handheld microphone can be used to pick up the sound at a close distance, and adjust according to the volume and mood of the microphone to highlight the charm of the singing.

2. Adjust the sound quality and volume. Because of the karaoke singing to KTV, the voice of the untrained person, the sound quality is not pure and lacks brightness, the male voice is prone to throat sound and hoarseness, and the female voice is prone to breath noise and arpeggio. Therefore, it is necessary to cut off the high frequency above 500MHz, and cut off the low frequency below 100Hz, and increase the brightness by 3-6dB in the middle frequency band to increase the brightness and make the sound clear and bright. Generally, the singer's voice is low and lacks loudness, so the volume should be adjusted as much as possible. It is also possible to increase the frequency band around 2000MHz, so that the processing can also increase the sound level.

3. Sound adjustment should be combined with the image. During the recording process, the karaoke sound source has basically adjusted the relationship between the balance between the instruments and the singing voice. The picture is closely combined with the singing voice. Each lyric is matched with the movements and expressions of the characters. Therefore, the singer is sung in the singing for the artistic conception on the screen and the actions and emotions of the protagonist, and indulges with the development of the scene and the development of the music. In short, the sight and the hearing are inseparable, and the size of the song field is imaginary, and it is necessary to adjust accordingly with the picture. This adjustment can achieve the realm of scene blending.

4. Adjust the ratio of the microphone volume to the accompaniment volume. Generally speaking, a good song, in terms of volume distribution, should be roughly 40c/o for accompaniment music and 60c/o for singing voice. If the singer is unfamiliar with the melody of the song, it is easy to sing the tune and not take the shot, then increase the accompaniment volume appropriately.

5. Beautify with reverberation. The characteristic of KTV singing is to add electronic reverberation to the singing voice, which can cover up some defects in the buzzing and vocalization. When a male whispers, the reverberation time can be shortened a bit, and the soprano can properly extend the reverberation time to increase the color of the sound. As for the singing environment, if the wall around the room is made of wood, it has a reverberation effect. At this time, the reverberation time should be shortened to avoid the blurring of the sound; in the case of no special requirements, the mixture can be mixed. The adjustment knob is adjusted to the middle position, that is, the ratio of the direct sound component to the reverberation component is approximately 1:1.

6. KTV private room audio howling tuning. If the high and low frequencies are prone to howling, it is not the tuning is not in place, the decoration has obvious obvious sound defects or both. At this time, you can try to properly attenuate the woofer of the microphone, keep the treble at 12 o'clock or raise it properly, then - slow - slow - raise the mic volume until there is a high frequency whistle and then properly call back to a safe volume position. Note that two microphones should be turned on at the same time, and at least one should be placed on the table. I believe that you should get a clear and relatively safe microphone effect with easy sound. (The premise is that the whole set of equipment including the microphone has a relatively flat frequency response, in fact, it means to have better quality. If the hardware is congenitally insufficient, you don't have to work hard. The equipment is changed first.) If the microphone gain is really not going to go, then only the 31-band equalization whistling frequency point is inserted in the microphone channel or the main channel.

The correct method of operation is to connect the wireless microphone to receive the power of the receiver and the audio system, and set the audio system level (0DB or +4DB), then turn the amplifier to the maximum output, and set the volume of the main output of the mixer. At 0DB, turn on the wireless microphone transmitter power, and then set the audio output gain of the wireless microphone transmitter to 70% to 75%, and set the channel potentiometer of the wireless microphone input channel on the mixer to 0DB; Finally, carefully adjust the mixer input gain, and if necessary, adjust the transmitter audio output gain to a small extent until the microphone is satisfactory.

I hope that the above points can provide help to everyone.
