Using my new Nu PC Audio card


Hi!
 Tomorrow I pick up my new Nu Audio card. https://www.evga.com/articles/01281/evga-nu-audio/
I am hoping I can connect it to my Nakamichi 630 preamp tuner in the #2 Tape Deck input output. This should work right? In a perfect world I'm thinking I can playback my WAV files and even record them from vinyl into Audacity like I'm using a cassette deck. Am I on the right track in my thinking.

Thanks
