Mitsubishi Integrates 5.1 Surround sound into a flat panel LCD TV.

Integrated Sound Projector
The secret behind this impressive package is Mitsubishi's innovative Integrated Sound Projector (iSP). The iSP eliminates the need for separate audio components to provide a clutter-free home theater system. In environments where running wires and placing speakers are not easily accommodated, the iSP provides a surround sound experience that cannot be matched.The iSP reproduces Dolby® Digital 5.1 channel surround sound from a single speaker cabinet positioned below the TV screen. The iSP enclosure houses a 16-speaker array that creates a 5.1 channel sound field. Through the use of an advanced algorithm, the iSP delays the sound at varying intervals to each of the 16 speakers. As a result, the speaker array generates 5.1 distinct sound beams that are focused directly and indirectly to the listener. The subwoofer or LFE channel is also available as an output of the TV for easy connection to an external powered subwoofer.

The iSP utilizes walls or other surfaces to reflect the left, right and surround sound beams to you. The effect of this sound beam reflection is that the side and back walls of the room become virtual speakers for the complete surround sound reproduction.
