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.

Time lag between the surround sound output
Front
speaker
from front speakers and rear speakers. By
speaker (R)
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.
Rear
speaker (R)
Direct tuning
Tuning method to let you directly enter a
station's frequency using the numeric buttons
on the remote. Use this method if you know
the frequency of the station you want.
Dolby Pro Logic Surround
As one method of decoding Dolby Surround,
Center
Dolby Pro Logic Surround produces four
Front
speaker
channels from two channel sound. Compared
speaker (R)
with the former Dolby Surround system,
Dolby Pro Logic Surround reproduces left-to
right panning more naturally and localizes
sounds more precisely. To take full
advantage of Dolby Pro Logic Surround, you
should have one pair of rear speakers and a
center speaker. The rear speakers output
monaural sound.
Rear
speaker (R)
5.1 CH/DVD
These jacks are used to input decoded Dolby
Digital audio signals, allowing you to enjoy
5.1 channel surround sound. Use these jacks
to connect a Dolby Digital decoder or a DVD
player with a built-in Dolby Digital decoder.
Front Preset station
speaker (R)
A radio broadcasting station that is stored in
memory of the receiver. Once you "preset"
stations, you no longer have to tune in the
stations. Each preset station is assigned its
own preset number, which lets you tune
them in quickly.
Surround sound
Rear
Sound that consists of three elements: direct
speaker (R)
sound, early reflected sound (early
reflections) and reverberative sound
(reverberation). The acoustics where you hear
the sound affect the way these three sound
elements are heard. These sound elements are
combined in such a way that you can actually
feel the size and the type of a concert hall.
Select 3 STEREO 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.
