speakers.

Surround sound
Sound that consists of three elements: direct
sound, early reflected sound (earh’
reflections) and reverberative sound
(reverberation). The acoustics where vou hear
the sound affect the way these three sound
elements are heard. These sound elements are
combined in such a wa\’ that you can actualK’
feel the size and the type of a concert hall.
• Types of sound
Early reflections Reverberation
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
As one method of decoding Dolby Surround,
Dolby Pro Logic Surround produces four
channels from two channel sound. Compared
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.
5.1 CH/DVD
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.
