影响晶体管功放音质的因素与对策

Factors Affecting the Sound Quality of Transistorized Power Amplifier

可变的时延影响功放的动态稳定。降低电路对进入非线性的敏感度,是降低TIM的一种有效方法。提高晶体管功放动态余量,是改善其音质的良好途径。设计不合理的过流保护电路,限制了功放在复合性阻抗负载下的输出功率。本文分析了以上原因,给出了解决方法。

Variable time delay effects on thd dynamic stabilization of power amplifiers. Abating the sltivity of circuit going into nonlinearity is a good method to reduce TIM. Increasing the head-room of a transistor power amplifier is a way to improve the tone quality. The over-current protective device designed bad will astrict the output of a power amplifier devicing a complex load. The reason about them was analyzed and the method was given in this paper.
