Yeah, Mike; it's exactly as Ken explained. All the left and right channels are simply duplicates and the center is the combined L/R. This isn't as realistic as the result from the ambience processing modes such as DPLII, since the ambience is a bit different, rather than being simply a duplicate of the front channel. I never use this mode, but it's commonly said that its best use is in a party type situation where a more nearly uniform stereo sound throughout the room is wanted.

No, it doesn't necessarily put more demands on the amplification, for the reason mentioned above by Fred and in my clarifying reply to him. If the overall volume is to remain the same, less power is needed for each individual speaker. If the volume is to be increased, more power is of course needed, but that would also be the case if the volume was increased by just making the mains louder.
