possible surround sound, select one of the
following four center modes according to
your speaker system.
« NORMAL mode
Select NORMAL mode if you have front
and rear speakers and a smull center
speaker. Since a small speaker cannot
produce enough bass, the bass sound of
the center channel is output from the front
speakers,

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 4 large room
or apart from your listening position.
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 ane pair of rear
speakers and/or one center speaker. You also
need to select the appropriate center mode to
enjoy a full effect.
Dolby Surround
Encoding and decoding system of Dolby
Surround sound for consumer use. Dolby
Surround decodes the extra channels on the
Dolby Surround-encoded sound tracks of
movie videos and TV programs and produces
sound effects and echoes that make the action
seem to envelop you.
The amplifier offers Dolby Surround as one
of the pre-programmed sound tields. If you
have rear or center speaker(s), we
recommend that you customize the Dolby
Surround sound field by selecting the
appropriate center mode to take advantage of
Dolby Pro Logic Surround sound.
Parameter
Variable of sound that composes sound
image, such as tone or delay time. You can
customize the pre-programmed sound fields
by adjusting parameters to suit your listening
situation.
Sound field
Sound pattern produced by a sounding
source or sources in a given environment due
to direct and reflected sounds and the
acoustics of the environment. The amplifier
offers 5 pre-programmed sound fields
(ROCK, POPS, CLASSIC, MOVIE and
GAME) to let you enjoy surround sound
easily.
Surround sound
Sound that consists of three elements: direct
sound, early reflected sound (earty
reflections) and reverberative sound
(reverberation) The acoustics where vou hear
the sound affect the wav these three sound
elements are heard. These sound elements are
combined in such a way that vou can actually
feel the size and the type of a concert hall. ;
