No, because the magic black box AC couples the microphone. There's a capacitor in series. That's the entire point. No DC comes out of it. Because that would likely destroy anything you connect it to.

>Well can you explain what I'm wrong about
The phantom voltage is just a power supply voltage, as long as it's higher than your signal level, you can build a circuit that works. 48 V is just normally used to keep the current low to prevent issues with cabling. Your signal level is still going to be like a volt, and if your mic is designed to handle voltages below 48 V, then your supply voltage will not matter a lot given competent design.

There's more to the circuit but here's the basic concept for you. I remember putting two caps in it for some reason but I don't remember why.

Yes, that is what phantom power is all about. Adding more volts.

I suppose, technically, it is.

The mic pre is a lot quieter if I turn the big mic off, but I agree, the set-up is good enough not to justify much change.
