DOLBY PRO LOGIC SURROUND, DOLBY 3CH LOGIC CENTER MODE
(For DOLBY PRO LOGIC SURROUND and DOLBY
3CH LOGIC)
You can choose from the following settings:
Center Mode Choices:
When using a center speaker:
@ NORMAL —Low range frequencies, which have little
effect on directionality and positioning, are routed to the
left and right front speakers. This allows you to use a
relatively small size speaker as the center speaker.
@® WIDE —If you use a large size center speaker, choose
this setting. The full frequency range of the Dolby Surround
center channel is routed to the center speaker.
When
not using a center speaker:
DOLBY
PRO
LOGIC
SURROUND only
@ PHANTOM—The
signal which would have been sent to
the center speaker is divided equally between the left and
right front speakers.
With DOLBY PRO LOGIC SURROUND,
monaural source
sound will be heard only from the center channel at settings
other than the PHANTOM
position.
SPEAKER INSTALLATION

If the rear speakers are positioned at an extreme distance
from the front and center speakers, the surround
leve
becomes unable to adjust and the surround effect will not be
fully achieved.
NOTE:
®
Jo avoid interference with the picture on a nearby TV set, use
magnetically shielded speaker systems.
This is particularly
important for the center speaker since it is usually located closest
to the TV.
@
Position the left and right channel speakers at equal distances
from the TV set and approximately 1.8 m (6 feet) from each other.
e
Position the center speaker above, below, or behind the TV set.
Sound may not appear to coincide with the picture if you position
it next to the TV set.
@
Rear speakers are best positioned slightly above ear level.
