Fidelity test跑mic出现error:THD+N......

Question

我在Fidelity test/class fidelity test，当run 到microphone里的“THD+N”时，出现error message:

Measured THD+N at -3 dB FS with respect to full-scale signal for channel 1 with +/- 100 Hz frequency tolerance is: 40.8268 dB; requirement is >= 65 dB; *** FAIL

事情紧急，烦请哪位高手指教一下，感谢！！

Answer 1

联系音频供应商吧。系统厂商自己似乎没办法解决这个问题。
