电源对影音器材具有关键作用与重大影响。无论是从音、视频设备工作原理分析,还是从实际表现效果观察,都会得出这一结论。以往,许多影音爱好者都不太重视电源,认为只要器材素质高就一定会有好的效果,这一观点在实践中已被否定。事实上,纯净、充足的电源供给才是系统表现最可靠的保证。作为器材的能量之源,电源在进入器材前一定会受到各种外界影响,不可能绝对无染,有时甚至会有各类非常复杂 Power supply audio and video equipment has a key role and significant impact. Whether from the sound and video equipment working principle analysis, or from the actual performance of the effect of observation, will come to this conclusion. In the past, many video enthusiasts are not too concerned about power, that as long as the high quality equipment will have a good effect, this view has been denied in practice. In fact, pure, adequate power supply is the surest guarantee of system performance. As the source of the energy of the equipment, the power must be affected by all sorts of external influences before entering the equipment. It can not be absolutely non-staining, and sometimes even all kinds of complicated
