I did a search on condenser mics and all I could find was a maximum of 10 volts, 2-10.? As my UBitXv6 is going to be my go-to radio when we loose power I am going to have to make some changes. I am going to use a buck converter to lower the voltage to the radio. so I can use it on my solar-charged batteries. When they go into equalization made the voltage can go to 15 volts.?
