Elaborate Karaoke system in use for the operation control key points:

(1) how to adjust the sound tone

If the sound processing is not good, will not only make sounds tedious, and it's going to make a musical instrument or singing have serious distortion, therefore, must not overlook the importance of sound processing. For men, the majority of low, missing sound treble, to improve the clarity of the singing, generally around to 3000Hz frequency component appropriately promoted; and girls and for the treble of the sound too much hair "tip" for the sound rolling, not too harsh, generally around the 400Hz frequency component as appropriate.

(2) how to adjust the sound reverberation time

Reverb is usually determines the length of the sound, the sound of color and clarity have direct effect. In General, bass singing, the reverberation time is shorter transfer to enhance audio clarity; if is the soprano singing time may be appropriate to extend the reverberation time in order to increase the sound of color. For concert venues, if the room surrounding wall is made of wooden materials, then its inherently have a reverb effect, you should adjust the reverb time, so as not to sound less blurred; on the other hand, if the room is the glass structure, or with velvet curtains and other sound-absorbing materials, this room is missing a reverb, it should be some reverberation time larger so that the sound happening there. Also, the size of the audience also has a significant impact, because the audience's clothing on sound also has great absorption effect. In General, the tuning can be in 1-2 seconds to select a feeling fit the reverberation time.

(3) how to adjust better to sound and mixing ratio of the amount of noise

Appropriately increase the percentage of mixed noise amount, to simulate natural reverb effect that makes sound full-sounding, can increase the viewers and listeners of stereoscopic effect. If the mixed sound too much and too little weight to direct sound makes sound serious distortion, as in the bathroom, the bath-house to hear sounds so vague, is known as the "bathroom" effect. Therefore, no special requirements, you can adjust the reverb knob in the center position, i.e. the amount of direct sound and the mixed sound weight ratio is 1: 1. In this way, the sound will not produce distortion and a reverb effect.

(4) how to adjust the microphone volume and good accompaniment volume ratio between

A nice amount of songs that are roughly allocated, should be accompanied by music and 40%, 60% of the singing voice, if the singer sound good, may be appropriate to reduce the number of the volume of the music accompaniment to prominent singers singing; if the singer on the song melody is not familiar, easy to sing out of tune, not taken on, in order to cover up these shortcomings, this may be appropriate to increase the volume of some accompaniment. But in action, you should be careful not to put the microphone volume too much larger as well as lost karaoke atmosphere; don't make accompaniment sounds too strong, but "drown" the singer's voice.

(5) how to adjust the pitch of the sound accompaniment music

Accompaniment music is based on the original singing tone and set the tone of the play, it is not possible to adapt each singer noise conditions. In order to be able to let the accompaniment music catering to every singer voice characteristics, tuning to cope with the singer's voice characteristics have accurate judgment. Singing, the first tone control is placed in the center position, neither increase nor decrease. A start, if the singer-have raised, and that don't have to adjust it; grumbling, singer if they feel the bass area can't sing, or treble zone behind, according to the actual situation will accompany the pitch adjustment to the singer to adapt tempo.
