I have a microphone, which is phantom powered. Now that microphone uses an XLR interface, which connects to a small device, that device connects to PC using USB 2.0 interface. Microphone capture and whatever has to do with microphone stuff works just fine.
But now the confusion is that many audio professionals use external hardware audio mixers (not like PC devices, shown as above picture), and they claim that a general PC can not do phantom power.
Why not? If the XLR microphone connects to a device, and that device connects to USB, can the PC operating system not send phantom power the same way?
If it's true, does that mean Linux or Windows or Unix what-ever OS it is, can't do Phantom Power and you need a different architecture for supplying Phantom power?
