Delay time
Time lag between the surround sound output from front
speakers and rear speakers. By adjusting the delay time of
the rear speakers, you can obtain the feeling of presence.
Make the delay time longer when you have placed the rear
speakers in a small room or close to your listening position,
and make it shorter when you have placed them in a large
room or apart from your listening position.
Dolby Digital (AC-3)
This is a new digital surround system proposed to reproduce
Dolby SR-D (the 3 dimensional sound system developed for
use in movie theaters) in the home. This technology allows
you to enjoy the full 5.1 ch soundtrack intended by the
filmmaker, in the comfort of your own home.
Dolby Pro Logic Surround
Decoding system of Dolby Surround sound standardized in
TV programs and movies. Compared with the former Dolby
Surround system, Dolby Pro Logic Surround improves
sound image by using four separate channels: off-screen
audio effects, on-screen dialog, left-to-right panning, and
music. These channels manipulate the sound to be heard and
enhance the action as it happens on the screen. To take
advantage of Dolby Pro Logic, you should have at least one
pair of rear speakers and/or one center speaker. You also
need to select the appropriate center mode to enjoy a full
effect.
