If your CD player uses digital, you can "stack" the digital on top. Meaning you can use "CD" for both. When the cd player is off, the receiver takes in the analog. When you turn on the cd player, then digital takes over. I do that on the SR707 as I have my CD player(DX390) connected tos-link, and a Belkin F8Z connected analog for the Ipad/Ipod/phones/computer.
