depends on what your gonna go through, i've run a matrix using my mics, and a sbd patch but i used a ring/tip insert cable. its basicly a stereo 1/4 > split like a Y into 2 separate mono 1/4 leads. that worked, using a stereo out from the board, through a mixer>dat. umm i'd say that, or use RCA's run out from there to your deck. they normally use their XLR outs to send signals to their amps on stage, or thats how i've run sound before. hope this helps. good luck.
