Hi. I am in Toronto, Canada and this is the first time on this web site. For a low output/low impedance mic I am trying to build a preamp that is powered by 48 volts phantom power from the mixer the mic signal is going to. Of course no DC voltage from the phantom voltage must get to the microphone because I will be connecting a dynamic mic or a ribbon mic to the preamp. I figure that maybe a fet or two fet transistors would be used in this circuit or a single dual IC such as a 5534. It’s best to write to me at firstname.lastname@example.org. Thank you for any help that you can give to me.
