多功能厅系统噪声的产生与抑制

The Production and Its Control Multifunctional Hall System Noise

多功能厅系统噪声问题常常影响整个系统扩声效果和图象质量 .确保较“干净”的电源向音视频系统供电 ;隔绝由外界噪声产生的干扰噪声 ;音视频系统的信号传输和正确配接是提高线路的抗干扰能力前提 ;

The noise often impacts the whole effect of audio amplification and the quality of images of multifunctional hall system. In order to restraint electromagnetic noise, some steps should be taken, among which it is the most fundamentally effective method to establish shielding system and earth connection network.. It also works to isolate the interference noise produced by outside noise. As the same time, it functions to ensure to relatively 'clean' power supply which can provide power-up to the audio and video system. The premise to improve the wiring′s ability against interference is that the signals of the audio and video system can be transferred and attached correctly.
