Mac Mini microphone input doesn’t work. Why?
This is the best answer I got:
“The Mac mini’s input is a line-level input, whereas the mic line on most analog headsets needs a mic-level input (to power the mic). The mini isn’t giving the mic any power, so it’s not going to work.
You need something to pull the level of that mic line up to what’s known as “line level.” A lot of people use the iMic, others use audio mixers that will provide power to the mic (and other inputs) while providing a line-level output for the mini to accept.
Alternatively, you can pick up an inexpensive USB headset. Logitech and Plantronics both make very affordable USB-based solutions.
Hope this helps.”
