Select NORMAL mode if you have front and
rear speakers and a small center speaker.

enough bass, the bass sound of the center
channel is output from the front 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 Dolbv Surround as one of
the pre-programmed sound fields. If you have
rear or center speaker(s), we recommend that
you customize the Dolbv Surround sound field
by selecting the appropriate center mode to
take advantage of Dolby Pro 1 .ogic Surround
sound.

Additional information
• 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.
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.
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.
