How to use professional stage audio equipment

　　Professional stage audio equipment is a kind of equipment with high technical content and requires artistic beauty. The equipment that can truly achieve perfection must be impeccable. Whether it is the design arrangement of timbre or the creation of the overall atmosphere, it must be just right. Professional stage audio equipment with good reputation can naturally do this, but its effect is a test for the operator. How to give play to the performance of audio equipment? Guangzhou Wanchang Audio Company will introduce it.

　　1、 Adjust reverberation time

　　The reverberation time of professional stage audio equipment has an impact on the quality and clarity of sound color. The reverberation of professional stage audio equipment is related to the length of aftertones. When singing, the bass can be adjusted to a shorter time to highlight the clarity; The soprano can extend her singing time to add color to her voice. If the wall of the room is made of wood, the reverberation time should be reduced to avoid unclear sound; On the contrary, if the room is hung with sound-absorbing materials such as flannelette curtains, the reverberation time should be increased to avoid dry sound.

　　2、 Balance microphone volume with accompanying music

　　Professional stage audio equipment should maintain 40% of the accompaniment music and 60% of the singing sound. If the singer has good timbre, the accompaniment music can be reduced to make the singing more distinctive; If the singer is not familiar with the melody, it is easy to sing out of tune and out of tune. In order to cover up the defects, the proportion of accompaniment music can be appropriately increased. If the accompaniment sound of professional stage audio equipment is too weak, most of the time, only the singer's singing will be heard, and the atmosphere will be lost; If the accompaniment sound is too strong, it will "engulf" the singer's voice, as if it were just a band playing music, which has a ruthless flavor.

　　3、 Handling the tone of accompaniment music

　　Some original singers have a relatively high range, and the accompaniment music released by professional stage audio equipment cannot take into account the noise conditions of each singer. In order to make the accompaniment music take into account the noise characteristics of singers, the sound engineers and tuners should play a quick auditory response. When singing, the pitch of the professional stage audio equipment should be controlled in the middle, neither rising nor falling. At the beginning of a song, if the singer can tune up, there is no need to adjust; On the contrary, if the singer cannot complete the original tone, he can adjust the transmitted tone to the corresponding sound area according to the actual situation
