D I G I T A L
Dolby Digital provides better sound quality, improved dynamic range and greater sense of direction, compared with conventional Dolby surround. Now, you are able to enjoy real Home Theater sound in your home.
DOLBY PRO LOGIC : This unit incorporates the Dolby Pro Logic Surround Decoder which performs the same functions for home playback as it does in the movie theaters. Use with Dolby Pro Logic program sources bearing the “ 
DOLBY SURROUND ” trademark such as video cassette tapes, laser discs or TV broadcasts.
DOLBY VIRTUAL : Dolby Virtual employs sophisticated digital processing to create the illusion of five “phantom” speakers. Therefore, this mode allows you to experience a realistic multichannel experience from any program source, through just a single pair of front speakers.
Manufactured under licence from Dolby Laboratories. “Dolby”, “Pro Logic” and the
THEATER : This mode provides the effect of being in a movie theater when watching a movie source that has a stereo sound track.
HALL : This mode provides the ambience of a concert hall for classical music sources such as orchestral, chamber music or an instrumental solo.
•When the 6 CH DIRECT INPUTS are connected to a 6 CH decoder or DVD player for a surround sound such as Dolby Digital or DTS, etc., you can enjoy the corresponding surround sound, too. (For details, see the operator’s manual of the component to be connected.)
Delay time
When the center speaker or the rear speakers is(are) closer to the listener than the front speakers, the sound from the center speaker or the rear speakers can arrive at the listener’s ears earlier than the sound from the front speakers.
In this case, the imaging is not as sharp and stable as it could be.
For audible improvement, the sound from center speaker can be delayed with the center delay time setting to synchronize the sound from the front and the center speakers and the sound from the rear speakers can be also delayed with the rear delay time setting so that the sound from the front and the rear speakers will be heard at the same time.
The optimum delay time will be different according to the room size and the acoustic properties.
It is adjustable in the surround modes except for the normal stereo mode. (For details, refer to “In the surround modes except for the DTS, normal stereo and Dolby Virtual modes, adjusting delay times of the speakers” on page 18)
