Mitsubishi's New Ultra-Thin LCD Delivers Surround Sound

The Integrated Sound Projector reproduces 5.1-like surround sound from a single speaker cabinet.

At last week's unveiling of LaserVue TV and other HDTVs in New York City, Mitsubishi Digital Electronics America, Inc. announced the introduction of their new Ultra Thin Frame Premium Flat Panel TV with Integrated Sound Projector (iSP) - their 149 Series. These TVs were designed for viewers who have been craving a complete home theater TV experience, but without the complicated set-up and operation. Mitsubishi's new product line up will come in 46-in. (LT-46149) and 52-in. (LT-52149) models.

How iSP Works

The integrated sound projector (iSP) reproduces 5.1 surround sound from a single speaker cabinet attached below the TV screen, which gives the flat panel the appearance of a slight chin. The small speaker enclosure houses a 16-speaker array that creates a full 5.1 channel sound field. Through the use of an advanced algorithm, the iSP delays the sound varying intervals to each of the 16 speakers. As a result, the speaker array generates 5.1 distinct sound beams that are precisely focused both directly and indirectly to the listener decoding both Dolby Digital and Dolby TrueHD surround sound. At this time, it does not support DTS.

One of the key features of the iSP is the easy-to-use, graphical user interface. Out-of-the-box, the iSP is set up to deliver optimal sound in a typical room setting. However, the user can simply enter specific room dimensions, e.g. 13 x 20, as well as the location of the main listening area. The TV placement and furniture placement are also adjustable.
