Does SACD & Redbook Playback req Two Interconnects

I visited a local dealer and checked out the Sony SACD A777ES and he couldn't get the SACD to output and I noticed two sets of outputs on the back. It played Redbook but not SACD. Worthless dealer. I couldn't find the Sony manual online (worthless sony web site stating this player is a CD Changer). None of the reviews I've red mentioned this problem.

If you want to play both redbook and SACD, do you have to use two seperate dedicated interconnects and pre-amp inputs?
If so, then do all SACD players require this setup?

PS I don't care about 5.1 multi-channel SACD at all.. (not meaning to generate flames or responses)

Thanks,
Chris
