Setting Up My Alesis Multimix 8 Usb Mixer, recording distortion Options

[Cali to Tex]

I am a beginner and I am having probs with recording. I am picking up a lot of static with the vocals. In fact, the track itself is being recorded on the same channel as the vocals but I have the sound is going directly into the headphones during a recording. Can someone help please!!!!! I am exporting files from Reason and FL 5 Studio into Vegas or Cakewalk. I have tried both and there is still helluva static and distortion being recorded. My setup for the mixer is correct and I am running out of ideas. Please help!!!!!!!!!!!
