you'll have to connect it to the second pre-out ( the one with the independent volume) set the volume on it to max and enjoy! you may also want to consider the new C372 which is supposed to be a step above the C370. of course it costs alot more too

i have a 370 and love it, i dont use the pre-amp section in it anymore though since i built myself a tube preamp which sounds quite a bit better
