need help setting up a TASCAM 424II

there's a line out in the back of the djx, I believe, and so just plug a 1/4" cable into that, and then plug the other end into one of the 6 inputs (channels 1-4, or 5/6, or 7/8) on the Tascam. You could also go from the headphone amp, if you adjust the input level on the Tascam.
or you can go into the stereo ins on the tascam on chanels 5 and 6 or 7 and 8....then adjust you're levels there.....
other wise sounds like you have a cool setup going there have fun man!
