How to debug the audio system
The difference between laminate speakers and ordinary home theater speakers is that as a device for restoring human voices, the song effect will be affected by the speakers, so the speakers are required to have excellent sound quality. There also needs to be enough power. If the sound quality of the speakers is not good or the power is not enough, the sound will be distorted when singing, which will greatly reduce the fun of singing, so a pair of powerful speakers is necessary. Some users are often willing to spend a lot of money on speakers and amplifiers, but are stingy on microphones. This is really a pity. The microphone is a key piece of equipment in karaoke. If the microphone is not chosen properly, the entire effect will be lost. Just imagine, the singing voice is dull, thin, distorted, and prone to howling. How can you enjoy it? Therefore, in the karaoke system, the selection of microphones cannot be careless. Cardioid and supercardioid dynamic microphones should be selected. Don't be afraid of the price. After using it, you will understand that the sound effect is different. Of course, the adjustment of the equipment is equally important. Please see the operation and adjustment of the Kara system below.
Save good timbre
If the timbre is not processed well, it will not only make the sound monotonous and tasteless, but also cause severe distortion of the musical instrument or singing. Therefore, the importance of timbre processing must not be ignored. For male voices, most people's voices are relatively deep and lack treble. In order to improve the clarity of singing, the left and right frequency components can generally be appropriately increased. Female voices mostly have too many trebles, which makes the voice sharp. In order to make the voice Loud and bright, not too harsh, and generally can appropriately enhance the left and right frequency components.
Set the reverberation time
Reverberation usually determines the length of the reverberation and has a direct impact on the color and clarity of the sound. Generally speaking, when a bass sings, the reverberation time can be adjusted shorter to improve the clarity of the sound. If a soprano sings, the reverberation time can be appropriately extended to increase the color of the sound. For singing venues, if the walls around the room are made of wooden boards, they will have a certain reverberation effect. At this time, the reverberation time should be adjusted smaller to avoid the sound being blurred. On the contrary, if the room is made of glass structure , or hung with velvet curtains and other sound-absorbing materials. Such rooms lack reverberation, and the reverberation time should be increased to prevent the sound from drying out. In addition, the size of the audience also has a great impact, because the audience's clothing also has a great absorption effect on sound. Generally speaking, the tuner can choose a reverberation time that feels suitable in seconds.
Regulate the proportion of direct sound and reverberation sound
Properly increase the proportion of reverberation sound, which is helpful to simulate the natural reverberation effect, make the sound full and pleasant, and increase the three-dimensional sense of the scene for the audience and listeners. If there is too much reverberation and too little direct sound, the sound will be seriously distorted, just like the sound heard in a bathroom or bathhouse, which is the so-called bathroom effect. Therefore, in the absence of special requirements, the reverberation adjustment knob can be adjusted to the middle position, that is, the ratio of the direct sound component to the reverberation sound component is. In this way, the sound will not be distorted but will also have a certain reverberation effect.
Control the ratio between the microphone volume and the accompaniment volume
For a good-sounding song, in terms of volume distribution, the accompaniment music should account for % and the singing voice should account for %. If the singer's tone is good, it can be appropriate Reduce the volume of some accompaniment music to highlight the singer's singing voice. If the singer is not very familiar with the melody of the song, it is easy to sing out of tune and out of time. In order to cover up these shortcomings, the volume of some accompaniment music can be appropriately increased at this time. However, during operation, care should be taken not to increase the volume of the microphone too much, so as to lose the atmosphere of the karaoke, and not to make the accompaniment sound too strong and drown out the singer's singing voice.
Adjust the tone of the accompaniment music
The accompaniment music is played according to the tone of the original singer, and it is impossible to adapt to the noise conditions of every singer. In order for the accompaniment music to take into account the voice characteristics of each singer, the tuner should have an accurate judgment on the singer's voice characteristics. When singing, first place the tone control in the middle position, neither raising nor falling. At the beginning of the song, if the singer is in tune, there is no need to adjust it. If the singer feels that the bass range cannot sing, or the treble range cannot keep up, the accompaniment tone can be adjusted to the range that the singer is comfortable with according to the actual situation.
In short, when singing with the karaoke system, the sound is beautiful and the sense of presence is strong. It has delicate and subtle high-frequency extension, and the high-frequency is clear and bright. The mid-frequency is very smooth and comfortable, the tone is bright, the low-frequency is mellow and sweet, and the low-frequency is powerful, and it dives very deep. You can configure an additional subwoofer to make the low-frequency enjoyable and let the body relax. Feel the shock of heavy bass
