Need Adaptor connect DJ Tech Turntable to Sony...

Question

I have purchased a DJ Tech Direct Drive USB Turntable for transferring my vinyl LP's into CDs. I want to hook it up with my Sony Mini Hi Fi MHCRG495 enroute to my Mac G4 so I can use the three stereo speakers.
Do you know what kind of adaptor I need ? I was looking at an RCA Scart Plug Adaptor but wasn't sure if that was the right thing to buy.
