Before Dolby Home Theater is enabled, you get only 2-channel playback output (from
the front speakers) when playing 2-channel stereo sources. You must play 4-, 5.1-, or
7.1- channel content to get 4-, 5.1-, or 7.1- channel audio effects. With Dolby Home
Theater enabled, 2-channel stereo content will be transformed into multi-channel audio,
creating a virtual surround sound environment
