前级三分频与二分频组合功放吴平前级电子分频方式与后级功率分频方式相比，在同等条件下，除成本较高外，有互调失真低，分频点稳定和不受扬声器阻抗变化的影响，分频器元件参数选择计算较灵活等优点。因此，通常发烧友自己动手制作也容易达到理想效果。今后，随着电子元... Compared with the previous stage power divider, the former stage three-way divider and two-way combinational power amplifier Wu Ping have the advantages of lower intermodulation distortion and stable crossover points under the same conditions, besides higher cost Not affected by changes in the speaker impedance, the divider component parameter selection more flexible and so on. Therefore, it is easy for fans to make their own ideal effects. In the future, with the electronic ...
