Glossary
Centre mode
Setting of speakers to enhance Dolby Pro
Logic Surround mode. To obtain the best
possible surround sound, select one of the
following four centre modes according to
your speaker system.
• NORMAL mode
Select NORMAL mode if you have front
and rear speakers and a small centre
speaker. Since a small speaker cannot
produce enough bass, the bass sound of
the centre channel is output from the front
speakers.
• WIDE mode
Select WIDE mode if you have front and
rear speakers and a large centre speaker.
With the WIDE mode, you can take full
advantage of Dolby Surround sound.
• PHANTOM mode
Select PHANTOM mode if you have front
and rear speakers but no centre speaker.
The sound of the centre channel is output
from the front speakers.

• 3 CH LOGIC mode
Select 3 CH LOGIC mode if you have front
and centre 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.
Dolby Pro Logic Surround
Decoding system of Dolby Surround sound
standardized in TV programmes 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 centre speaker. You also
need to select the appropriate centre 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 programmes and
produces sound effects and echoes that make
the action seem to envelop you.
The amplifier offers Dolby Surround (PRO
LOGIC) as one of the pre-programmed sound
fields. If you have rear or centre speaker(s),
we recommend that you customize the Dolby
Surround sound field (PRO LOGIC) by
selecting the appropriate centre mode to take
advantage of Dolby Pro Logic Surround
sound.
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.
