You should be connecting a turntable to a phono input, not a cd input. That input would provide you with the needed gain as well as equalization. I'm not sure off hand if that receiver has one. If not, you'll need to pick up a phono preamp, and connect your turntable to that, and send the preamp's output to your cd input. That oughta do it. You can find a preamp on eBay, ranging from under 20 bucks to a few hundred.
