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)

audio (which means identical to the original masters) and results in exceptional
clarity throughout a true 360˚ sound field.
