Center Channel Downmixing
Center channel issues are special. The center channel was first developed by Dolby to allow voices to sound like they were coming from the characters in a movie watched on a small TV set. With a stereo system and small TV, the voice track moved back and forth with the action. The sound stage of the audio system was perhaps 6 feet wide but the TV only 2 foot wide. The characters did not stay in the picture. In such a case, a center channel is useful. Now we consider a wide screen home theater with a projector and large screen. Now the audio and video stages match and a center speaker focuses the voices right in the center of the screen even when they are not. In this case elimination of the center speaker is advantageous.
There are two ways to downmix the center channel. First, by going into the Player setup menu, the center speaker can be turned off. The center track is downmixed into the front channels. A better way is by using the AUX channels. The center is blended with the fronts right at the output. The center output is not used and can be used as a second sub channel. The big advantage with this setup, is that the center
