The L/R preamp outs from the prepro go to the HT bypass input on the stereo preamp, so only the stereo pre is directly connected to the amp powering the front L/R speakers for both HT or 2-channel audio. That's basically it.
BTW, you don't necessarily need to limit yourself to stereo preamps with an HT bypass input. Any unused line-level input will work, you just need to set a reference volume level on the stereo pre so it matches volume with your other HT channels (usually use 12:00 when setting channel balance to make it easy). Anyway, hope this helps.
