电源对扩声系统的工作质量有着十分密切的关系,不仅直接关系到扩声系统的效率,也会对扩声的声质量产生直接影响。所谓“声质量”,就是包含扩声系统的底噪声、有效动态及音质等,其中系统噪声除了电声器材的因素,还与电源的纯净性密切相关,并关系到系统在一定质量要求下的有效动态响应,其有效动态响应和音质也与电源电压、电流的稳定
The power supply has a very close relationship with the quality of the sound reinforcement system. It not only has a direct impact on the efficiency of the sound reinforcement system but also has a direct impact on the sound quality of the sound reinforcement. The so-called “sound quality” is to include the bottom noise of the sound reinforcement system, effective dynamic and sound quality, among them the system noise is not only the factor of the electroacoustic apparatus, but also is closely related with the purity of the power, and is related to the system under certain quality requirements Effective dynamic response, the effective dynamic response and sound quality and power supply voltage and current stability
