Dolby Virtual 
A Virtual Dolby Surround System attempts to create the same surround effect produced by a
Phantom Centre Speaker
The general conceptual model of a Virtual Dolby Surround System
Left Front
Right
divides the centre signal equally between the left and right speakers to achieve a Phantom Centre Image. It also processes the Virtual surround signal before sending it to the left and right speakers, creating a virtual image around the listener.
The virtual effect is stronger with Dolby Surround encoded movies. Switching the Dolby virtual to OFF gives you normal television sound.

Helpful Hint (
N
Normalization)
By pressing the Normal “N” Button on the Remote Control while the Sound menu is displayed, the selected menu will be changed to the Normal Mode.
Normalization will not occur if the menu is not displayed when the “N” Button is pressed.
The Normal mode is the factory preset condition. Returning to this original condition is called “Normalization”.
