Sound Menu Operation
Dolby Virtual
A Virtual Dolby Surround System attempts to create the same surround effect produced by a multi-channel
system using only the left and right speakers.
The general conceptual model of a Virtual Dolby Surround System 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.
