ryt folks im purchasing two gemini tt 02 turntables
i have a selection of software on my PC that allows timecode setups including mixvibes obv

so when i purchase these decks and two timecode vinyls what else do i need to have in order to hook then up to my PC ?
does the output from the mixer (which i have also yet to purchase) need to go through an interface? would any rca into usb interface do the job or does it specificly have to be a audio 8 interface?
also when i purchase these decks theres no mixer, can i use the internal mixer on my software and just have the deck(s) goint straight into my laptop?
sorry if this is posted in the wrong section im a neewby =)
