笔者在音频测试过程中,遇到了一些因测试方法不妥造成的问题。以美国Audio Precision生产的便携一体化音频分析仪(含信号发生器)为例,做如下分析,供大家在音频测试中借鉴。此音频分析仪如图1所示。左下侧2个卡侬头为信号发生器的A、B路输出端口,对应的左上侧2个卡侬头为音频分析仪的A、B输入端口;右上侧部分用于调整信号发生器输出频率;右下侧部分用于调整信号发生器输出幅度。
The author in the audio test process, encountered some problems due to improper testing methods. To the United States Audio Precision production of portable integrated audio analyzer (including signal generator), for example, do the following analysis for your reference in the audio test. This audio analyzer is shown in Figure 1. Left 2 XLR head for the signal generator A, B output port, corresponding to the upper left 2 XLR head for the audio analyzer A, B input port; the upper right part of the signal generator for the adjustment of the output frequency ; The lower right part is used to adjust the signal generator output amplitude.
