DVD thru Mark Levinson 390s

I've set DVD to output PCM, but whenever I hit input on the ML's remote all I get is "no preamp". Can I do this or what?
Hello Keith,
You can email Madrigal with your question at their web site. Todd Sutherland will get back to you ASAP and he is very informative. Thanks, Paul
Well, I am curious as to what is happening, given that I am an owner of a 390s (and so are many others out here), so any information anyone has (littlemasterfrog? Pman172?)... Please post!
I don't believe the 390s does 24/96 conversion of any kind.
It will "upsample" standard CD's to 24bit depth at 352khz.
