Case introduction: Walk into Longgang Times School and feel the charm of Snick Audio! According to the needs of the school, the concert hall is mainly used to arrange student stage performances, external art exchanges and other on-campus artistic activities, as well as provide various meetings and activities in the school. First of all, when using sound reinforcement equipment everywhere in the hall, the sound must have a certain loudness, and the loudness must be relatively uniform everywhere. There must be no focus, that is, the place where the sound is focused and particularly loud, and there must be no blind spots, that is, the place where the sound becomes weak for some reason. The series has a linear sound source structure with uniform sound; small box, high power and high sensitivity. Series bass slightly: The low frequency slightly can provide clean, deep and explosive low frequency sound effects. The power amplifier adopts a series with a built-in limiter, which is a protective circuit that can very effectively prevent damage to the speaker. Series power amplifiers have strong anti-interference capabilities and work in the switching state. They have better anti-interference capabilities and make the sound quality more pure and thorough. The peripheral uses digital pre-processor and power sequencer. The microphone is equipped with a feedback howling suppression and weakening function, which can effectively reduce feedback howling. Feedback and evaluation: After the construction of the sound reinforcement system was completed, the school has held various cultural performances many times. After on-site evaluation and acceptance, the sound has been recognized and praised by the school, providing excellent sound reinforcement services for the school to organize various activities.
