Center mode
Setting of speakers to enhance Dolby Pro
Logic Surround mode. To obtain the best
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 small center
speaker. Since a small speaker cannot
produce enough bass, the bass sound of
the center channel is output from the front
speakers.
• WIDE mode
Select WIDE mode if you have front and
rear speakers and a large center speaker.
With the WIDE mode, you can take full
advantage of Dolby Surround sound.
• PHANTOM mode
Select PHANTOM mode if you have front
and rear speakers but no center speaker.
The sound of the center channel is output
from the front speakers.
• 3 CH LOGIC mode
Select 3 CH LOGIC mode if you have front
and center speakers but no rear speaker.
The sound of the rear channel is output
from the front speakers to let you
experience some of the surround sound
without using rear 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 a large room
or apart from your listening position.
Direct tuning
Tuning method to let you directly enter a
station’s frequency using the numeric
buttons. Use this method if you know the
frequency of the station you want.
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.
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 receiver offers Dolby Surround (PRO
LOGIC) as one of the pre-programmed sound
fields. 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.
Effect level
Combination of the level of early reflections
and reverberation. You can adjust the effect
level in 6 levels. As you select higher levels,
the room becomes “live,” and as you select
lower levels, the room becomes “dead.”
