Concert stage sound design and requirements

The primary task of the stage sound design of the concert is to plan the performance of the sound. The requirement for the sound is to reproduce the sounds and effects of the pre-recorded records on the scene. It is to use the sound equipment and technology to sing the songs on the stage and use the musical instruments to make the sense of music in the recorded record to the ears of the audience. The timbre requirements of the concert are clear levels and positioning, that is, the size of the instrument sound volume and the sense of position before, after, and left and right. In addition, the voice of the singer should make the audience have a sense of intimacy, that is, a sense of distance.

The concert is mostly a two-box performance layout, one compartment is the stage, the other compartment is the auditorium, so the audio system mainly has two major systems, one is the auditorium audio system, and the other is the audio return system of the band and singer .

The audio system in the auditorium mainly processes the voices of the actors on the stage and transmits them to the ears of the audience. The coverage of the stage sound should ensure that every live audience can enjoy the performance under the conditions of the same volume, the same bandwidth, the same timbre and the same spatial effect. If the stage is a single-sided stage, the sound layout mostly imitates home stereo sound, and a set of speakers are installed on each side of the stage. The sound layout of the three-sided table and the middle table is mostly a group of speakers vacant in front of the audience and in the middle of the table. There are three groups on the three-sided stage. If the stage is on the north, one set of speakers is placed above the east, south, west, and Taichung, and the middle stage is hung from the east, south, west, and north. A set of speakers. Each group of speakers is reproduced in mono, and some sound designers have designed speaker layouts specifically for stereo. A group of speakers are placed at the left and right of the desk to imitate the 2-channel stereo layout of home audio.

The audio feedback system is mainly used to mix the actor's singing voice and musical instrument sound to the individual due to the needs of individual actors to achieve mutual monitoring, synchronization and grasp the atmosphere of the scene. The audio equipment is a special return mixer and return speakers. The operating principle is that the actors on the stage can clearly hear themselves and others' performances. At the same time, the sound of the return system will not affect the audience. The return system basically needs to ensure that every player has all the way back, using headphones or placing a small speaker, the closer to the player's ears, the better. The return system of the singer is more complicated. Many sound designers will place multiple return speakers within the range of the singer. The return tuner needs to send the return signal to the return speakers near it according to the position of the singer. The return speakers and microphones on the board should be turned off to reduce interference and noise.
