The first -level literary performance of the theater stage, the first one requires audio art. First of all, the quality of the audio and color must be guaranteed, the sound of the sound is beautiful, and the outdoor open -air art performance. The first requirement is the audio technology. First of all, the literary performance must be guaranteed In the accident and successfully completing the art performance task, because the outdoor literary performance is more difficult than indoor performance, there are many specific technical requirements:

Calculate the specific value of the sound field.

Second, the speaker must be hoisted: the outdoor literary performances can not be too low, and the low -level sound wave sound waves are easily sucked by the audience's human body, producing the phenomenon of plundering sound absorption, especially the high audio loss. Therefore The horn and outdoor special speakers (high -power treble angle in the speaker), so that the sound waves of the speaker are far from radiation in the air, so that the auditorium can get enough loudness.

Third, select high -sensitivity MIC, so as to enhance the sound gain of MIC and enable the auditorium to get enough loudness. Outdoor performances are often far away from the distance between MIC and the mixer, so it is better to choose wireless MICs to pick up.

4. Protecting power circuit: The energy of the speaker system comes from the power grid circuit. If the power circuit fails the sound system, there will be problems. Therefore, the power circuit should be used to carry out technical guarantee by local professional electricians. The entire line mixer to the indoor power gate or temporary electric car shall be protected by special security personnel.
