Input capture device problem

[deboogieman]

Hei,
I have a pioneer DJM 350 mixer which i have connected to my laptop via the mic input to enable me broadcast through winamp, however, my shoutcast DSP plugin does not capture the external device. I connect RCA /3.5mm cable from the output of the mixer into the mic input of my laptop. I have enabled recording device settings in windows, but the shoutcast DSP plug in read: "no available capture device". HELP!!!!!!!!!!!
