Yes, that should work, and I note that one reviewer on Amazon ended up with much
the same arrangement when he discovered the phantom power wasn't really 48V.

Two other concerns I see reading the flyer for that unit:

It can ONLY be powered from the USB jack which could lead to more noise issues
(the Power from the USB port on your computer can be quite noisy). This is something
that can usually be cured by adding an external powered USB hub.

There does not appear to be any way to switch off the phantom power, such as it
is. For a few microphones that can be a big issue.

Not having any personal experience with this unit there isn't much more I can say.

This is precisely my objection to this mixer. Your Phantom Power Inserter is designed to supply proper 48 volt phantom power to the microphone and naturally assumes there's nothing on the mixer side. There is something on the mixer side, but it's not 48 and could damage the phantom power inserter. And you can't turn it off.

Will you be doing sound-on-sound or overdubbing? Will you be singing four part harmony to yourself? This is where I get fuzzy on you. I certified my analog mixer and a separate USB adapter for use in perfect overdubbing.

That USB adapter (UCA-202 or one of the others in this family) will work with almost any computer or mixer. I use Macs but that's it connected to a Windows machine.

You can listen to your older tracks and sing a new part as needed, and you can hear the final mix as you sing it.

That's important. Most of the ways of overdubbing do not support a live mix. You can sing to the older tracks as much as you want, but it will be a mystery what the mix sounds like until you play it back three minutes later.

No you can't normally listen to the computer. Those sounds are almost always late and it's like singing into a canyon.
If you're not overdubbing, then you can listen to any mixer at the headphone connection. Remember, you can't hear the computer that way...
