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.

adjusting the delay time of the rear speakers,
you can obtain the feeling of presence. Make
the delay time longer when you have placed

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
Front
speaker (R) 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
Rear
speaker (R)
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 system offers Dolby Surround (PRO
LOGIC) as one of the pre-programmed sound
fields. If you have rear or center speaker(s),
we recommend that you customize the Dolby
Surround sound field by selecting the
appropriate center mode to take advantage of
Front
Dolby Pro Logic Surround sound.
speaker (R)
Preset station
A radio broadcasting station that is stored in
memory of the tuner. 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
Rear
them in quickly.
speaker (R)
Sound field
Sound pattern produced by a sounding
source or sources in a given environment due
to direct and reflected sounds and the
acoustics of the environment. The system
offers pre-programmed sound fields like,
PRO LOGIC, THEATER, and HALL (etc.) to
let you enjoy surround sound easily.
