Center mode
Speaker setting to enhance the Dolby Pro Logic
Surround mode. Select one of the following
four center modes according to your speaker
system.
• NORMAL mode
Select NORMAL mode if you connect a
small sized active center speaker to this
speaker system. Since a small speaker
cannot produce 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.
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.
