Hi Ken, Thanks for your suggestion. These mics directly come with 3.5mm TRS, like a headphone audio jack. I will get 3.5mm TRS female to XLR male cable and have a try. Will let you know the result. Thanks a lot!
I have just purchased a new UMC 404HD. I want to do multiple-channel recording using two small-scale MEMS microphones with 3.5mm TRS. When I used the 3.5mm-1/4 TRS adapter to plug in the microphones to the UMC 404HD, my macbook can regonize the UMC404HD device with 4 channel inputs, but there is no audio signal, even if I turn the gain knob all the way to the right, there still no signal. I am not sure what is the problem.
