When you use an external phantom power supply to power an AT4033, is there any voltage going back to the sound board? If so, how much?
I am wanting to use the AT4033 as a ham radio microphone. I have a 48 volt external phantom power supply to operate the AT 4033.The ham radio supplies 8 volts to the mic and has to be between 250 and 600 ohms impedance. I have a 600 ohm in-line impedance matching transformer, so i believe i have the impedance covered. I'm really concerned about any voltage back to the ham radio from the microphone/phantom power supply. My radio is a TS 2000 Kenwood.
