Well, audio seems to like to go from an output of a device to the input of another. Not sure why that is, but it seems to work well that way....
You could try using the Track Outputs of your 4 track, or the Stereo outputs if you don't have Track out's, to the input of your soundcard. What kind of cables you need depends on the input of the soundcard and the output of the 4 Track eh? It will either be RCA or 1/4" TS (tip-sleeve...a regular guitar type cable) outputs from the 4 Track, and on your soundcard, the Line Input with be a Mini Plug TRS (tip-ring-sleeve....like a headphone connector) at the Input. The input of the soundcard will record in stereo, but might be able to record in Dual Mono (meaning left side is one channel and the right side is another channel) but this could also be software dependent.
The 4 Tracks Direct Track Ouput will be mono, and the Stereo output will have 2 mono jacks. So, depending upon how you want to transfer to the PC, you have some options.
No matter what, you will need a cable that is Mini Plug TRS to Dual Mono to interconnect the two. Since the soundcard does not have seperate jacks for Left and Right input, and only has 1 "stereo" jack for handling left and right input, you have to have a cable that will split that jack into Left and Right, because the 4 track has SEPERATE Left and Right outputs, and in addition, the Direct Track Output is Mono.
Radio Shack makes just the connector you need.
The
http://www.homerecording.com main site has some tutorials on hooking up stuff to sound cards. Feel free to read though some of that, and to also READ YOUR MANUALS!!!
Good luck.
