19. SoundConnect 2 mic power supply

This SoundConnect 2 can power either one or two microphones, so it is a great choice for audio test applications where two microphones need to be powered simultaneously, for example headphone testing, stereo measurements, or when you need a reference microphone as well as your DUT microphone for substitution measurements.

SoundConnect 2是一款小巧而坚固的USB控制麦克风电源和调节功放器。它可以供电给一个或两个麦克风，所以对于需要同时对两个麦克风充电的音频测试应用来说是理想的选择，像耳机测试，立体测量，或者在需要一个参考麦克风和你的待测麦克风来做替代测量的情况下。
