许多日本高级音响器材(包括Hi-Fi功放、AV功放、CD机、SACD机等),不仅外表做得金光灿灿、金碧辉煌,就连内部的机座,甚至是机壳都镀上一层黄橙橙的铜箔。这不仅仅是为了防锈,或是提高器材的挡次,更主要的是为了防止电磁干扰,提高机器的性能指标。大家知道,随着电子技术的飞速发展,在我们的生活空间不可避免地会出现越来越多的电磁干扰(Electro Magnetic Interference简称EMI),其负面
Many Japanese advanced audio equipment (including Hi-Fi amplifier, AV amplifier, CD player, SACD machine, etc.), not only looks glittering, magnificent, even the internal base, and even the case are coated with a layer of yellow and orange Orange copper foil. This is not only for rust prevention, or equipment to improve the block, the more important is to prevent electromagnetic interference and improve machine performance. As we all know, with the rapid development of electronic technology, more and more electromagnetic interference (Electro Magnetic Interference referred to as EMI) will inevitably occur in our living space. The negative
