When dealing with active mics with XLR outputs, this external phantom power is most often supplied with phantom power. Microphones that require phantom power are designed to accept and utilize this DC voltage on pins 2 and 3 relative to pin 1.
Similarly, most microphones that do not require phantom power some vintage dynamic mics have issues are designed to block the DC voltage on pins 2 and 3 relative to pin 1. Electrical shorting issues would arise if pin 2 was connected before pin 3 or vice versa.
Similar issues would arise if pin 1 ground was not connected before pins 2 and 3. XLR solves this with its design. XLRs connect pin 1 first, followed by pins 2 and 3 simultaneously, protecting our microphones from electrical damage and allowing for safe and effective phantom powering.
