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 surround 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.

speaker (R)
By adjusting the delay time of the surround
speakers, you can obtain the feeling of
presence. Make the delay time longer when
you have placed the surround 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
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,
Dolby Pro Logic Surround produces four
Center
channels from two channel sound. Compared
Front

with the former Dolby Surround system,
speaker (R)
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 surround speakers
and a center speaker. The surround speakers
output monaural sound.

DVD/MULTI CH
These jacks are used to input multi channel
audio signals, allowing you to enjoy 5.1
channel surround sound. Use these jacks to
connect a Dolby Digital decoder, a DVD
player with a built-in Dolby Digital decoder
or TV satellite receiver.
Preset station
Front
A radio broadcasting station that is stored in
speaker (R)
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
speaker (R)
Select 3 STEREO mode if you have front
and center speakers but no surround
speaker. The sound of the surround
channel is output from the front speakers
to let you experience some of the surround
sound without using surround speakers.

Surround sound
Sound that consists of three elements: direct
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.
