Virtual
The five different Virtual modes create sets of virtual speakers using the actual existing speaker system which
could be a six or three speaker system.
1) V. Multi Dimension : Uses 3D image processing to create four sets of virtual rear speakers surrounding
and positioned at an elevation of 30 degrees higher then the listener from a six-speaker system (two
actual rear speakers). Depending upon where the actual rear speakers are positioned, the virtual speakers
positions will vary (ref. Figures. 2-3, 2-4 and 2-5). The position of the rear speakers (Side, Mid or Rear)
must be programmed in the A/V receiver SET-UP menu for this sound field effect to work properly.
NOTE : The virtual speakers are placed at an elevation of 30 degrees higher then the listener to further
emulate the theater venue. The surround sound speakers in a theater are always higher then the listeners’
position.
