有些售价500元以下的功放,一开机就“嗡嗡”乱叫,令人心烦,本文介绍几种处理方法: 1.电源及接地点处理很多功放滤波电容均偏小,有些只有1000μF,可将其换为10000μF/50V,并在其两端并一只0.22μF的GBB电容,这样不仅可以降低静态交流声,而且可以提高大动态时瞬态力度与解析力。有些功放虽然经过上
Some amps priced below 500 yuan, a boot on the “buzzing” screaming, upset, this article describes several treatment methods: 1. Power and ground point handling A lot of power amplifier filter capacitors are small, some only 1000μF, Change it to 10000μF / 50V with a 0.22μF GBB capacitor at both ends, which not only reduces static humming but also improves transient dynamics and resolving power for large dynamics. Although some power amplifier after
