What voltage does the instruction/manual say the mic needs to operate? A lot of "studio style" microphones require 48v and they get the power off the sound board it is hooked to. To hook one up to a radio the audio should feed through to PS via an output, you will have to use a handheld or foot pedal for the PTT switching like ones used on a Heil mic.

If you have a cord that goes from the mic to the PS than half your battle is won, follow the schematic or instructions for the audio and ground hookup from the PS to the radio. Sometimes a diode is required to keep any power feedback on the ground side when making up the PTT.
