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.

Dolby Pro Logic Surround
As one method of decoding Dolby Surround,
Dolby Pro Logic Surround produces four
1 switched 120 W/1A
channels from two-channel sound. Compared
max
with the former Dolby Surround system,
Dolby Pro Logic Surround reproduces left-to-
2 switched 120 W/1A
right panning more naturally and localizes
max
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
1 switched 100 W max
monaural sound.
Center mode
2 switched 100 W max
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.
11.4 kg (25 lb 1 oz)
10.8 kg (23 lb 12 oz)
• 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.

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 sound format for movie theaters is more
advanced than Dolby Pro Logic Surround. In
this format, the rear speakers output stereo
sound with an expanded frequency range
and a subwoofer channel for deep bass is
independently provided. This format is also
called "5.1" because the subwoofer channel is
counted as 0.1 channel (since it functions only
when a deep bass effect is needed). All six
channels in this format are recorded
separately to realize superior channel
separation. Furthermore, since all the signals
are processed digitally, less signal
degradation occurs. The name "AC-3" comes
from the fact that it is the third audio coding
method to be developed by the Dolby
Laboratories Licensing Corporation.
5.1 CH/DVD jacks
These jacks are used to input decoded Dolby
Digital (AC-3) audio signals, allowing you to
enjoy 5.1 channel surround sound. Use these
jacks to connect a Dolby Digital (AC-3)
decoder or a DVD player with a built-in AC-3
decoder.
Preset station
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.
