Lighting and sound engineering is a relatively large project, and it includes a lot of things, and the price of the instruments is also very expensive, so we should pay attention to the rental of lighting and sound projects, so what problems do we need to pay attention to? Come with me to find out! 1. First of all, pay attention to whether there is a problem with the pronunciation in the audio equipment. The sound should be humming or ethereal. 2. Pay attention to distinguish whether the speaker has a very sharp or abnormal sound, so as to avoid the problem of inconsistent performance. 3. There is also the detection of human voice. Will there be distortion or muffled sound after the sound transmission? 4. For the bulb, pay attention to whether there are damaged bulbs, so as to avoid disputes in the later stage.
5. There is also whether there will be sudden situations during the operation of the lights, so check in advance.
