I recently purchased a rode nt1a studio condensor mic. The interface I planned on using doesn't have phantom power and this was a mistake on my part. I do have a mixing board with phantom power, but it is typically used for live sound. If this would power the mic, I just need a usb adapter but if it doesn't I need a new interface. I would rather not spend money on a new interface, so I was wondering if the mixing board would work.
