    However, there are many wonderful vintage microphones and some new ones with, especially ribbon mics that have a lower impedance of around 50 ohms. The MPA-201 has a variable impedance control to change the input impedance from 1200 to 600 or 300 ohms allowing you to connect a variety of microphones correctly. Oh by the way,…. Sometimes you can get an awesome result...
