Reply to Sampling from the S4 to Maschine on a Mac

Hi, i posted this question in NI's community with no help, im hopin perhaps someone can point me in the right direction

i have my denon dn-hc4500 connected to my mixer, denon dn-x800 and sending the output to the S4's Input Channel D 3+4 In.
I can hear whatever track i play on my external dj set but the Maschine is not picking up the audio.
I have installed Soundflower on my Macbook Pro with OSX 10.6.7 because that what someone suggested in reading online but i dont know g=how to configure Soundflower
Maschine is on it latest update 1.7

Thanks for all your help !!
