The Sound
If you are listening to a digital broadcast or getting your digital audio signal from a DVD player, you'll enjoy the same high quality sound* you expect from a CD. Compared with the flat, FM-quality noise available from an analog signal, your ears will be treated to rich, lifelike sounds.

The highest level of digital broadcasts will carry audio signals in Dolby^® Digital surround sound format, a feature that you will be able to take advantage of with the right home theater equipment. Dolby^® Digital differs from its more familiar predecessor, Dolby Pro Logic, in that it uses five separate audio channels plus an additional channel for special low frequency effects.

The sensational sound quality offered by Dolby^® Digital creates the convincing impression that the action in the film is taking place all around you. The horses galloping toward you from your screen will sound like they are passing by you on both sides and then disappearing behind you. The musicians performing the soundtrack will seem to be positioned all around you. Astonishingly real, Dolby Digital truly offers a 3D sound experience.

The diagram below illustrates a typical surround sound setup:

Simulated surround sound
If you don't wish to make the investment in a home theater system at the time you purchase your HDTV monitor, you'll still enjoy excellent sound. Most of today's HDTV monitors come with audio features built to mimic the ambience of surround sound without the need for rear speakers. Simulated surround sound features work effectively by manipulating the audio cues that provide the sensation of three-dimensional sound.

*It is important to note that digital broadcast will not improve the quality of the original material it is produced from. Recordings that were originally recorded in mono will still sound like mono when broadcast digitally. Whatever the quality of the material, you will hear it at its best with Dolby® Digital.
