ok lets see...

1. you need a pre-amp if your getting that condensor mic...better yet if you get a condensor mic period your gonna need phantom power aka a pre-amp.

2. you will need 2 cables, there is a imput and output on the pre-amp, you plug the cable that leads from your mic to input. so you will need a cable with male and femal XLR connectors. this cable goes from your mic to the input. now you need a 1/4"-1/8" cable (1/4" connecter on one end- 1/8" connector on the other) this will plug into the output directly into the microphone jack of your laptop

hope that helped
