摘要
阐述了扩声系统中扬声器系统与功率放大器的功率配接及相关问题,分析了扬声器系统的非线性失真和目前标准中所规定的几种功率及其测量方法。
issues about power matching between clusters and power amplifiers in sound amplifying system as well as correlated problems were illustrated. The nonlinear distortion of speakers was analyzed, and several power options and the correlated measurements advised by the standard were presented.
