How do I hook up 2 preamps to one amp

I have a NAD preamp that I use for music. I have a Lexicon preamp that I use for Video. The problem is I have 1 five chanel amp that I need to use for both preamps. When I try to use rca splitters/y adapters, my speakers play at a low volume. If I disconnect one preamp, the speakers play louder. What should I do to allow both preamps access to my 5 channel amp and not have humming or low volume.

Herman has it right. Line out to line in always works and tape outs are independent of front panel controls. But based on the rather funky arrangement and weird signal flow, combined with probable tape output selectors, lots of ways to get confused and have no sound (flipping buttons madly trying to get audio until YES full output into the amp). Simple is always better sound anyway, use everything through the Lexicon....It must have a 2 channel mode......

Elizabeth,

What he said about the tape loop or what he said about just using the Lexicon?

If the stereo preamp has a Home Theather bypass input, you can connect the Krell front LR pre out to that input.

When you are watching movies, switch the stereo preamp to HT bypass mode.

My Bel Canto Pre3 has an input I can configure for that.

As for my Audio Research Reference 5 (PROC mode).

Go to radio shack and buy a double pole double throw switch. Connect each pre to one side of the switch and the amp to the center. By flipping the switch you will alternate between pre A or pre B feeding amp C.
