The multi-room capability will give you the amp side of the equation. You then supply an additional pre-amp; source; & speakers. Denon & SONY offered this feature on both their stereo and HT receivers. The situation that I was describing comes up (used to come up) with HT receivers a lot, because the "B" line would be the same line used for the rear & center channel speakers. So, you would wind up running 5 speakers at the same time on the same line and the line resistance could go down to 1 ohm and you would have the protection circuitry kick-in.
