IF you were talking to me, that NOT how I do it. The Denon 2 front channels feed the preamp; the remaining 4 channels feed the processor (2 rears, center and sub). For movies, just adjust the volume controls on the pre and processor so they match, and you're done. That way the pre still controls the left and right speakers, which was my goal (big price and quality difference between my Preamp and the movie Processor).
Hope that helps - there are obviously several ways to achieve multichannel from a 2 channel system.
