DOLBY 3CH LOGIC
Combining the rear speaker signal with that of the front
speakers results in your being able to enjoy a regenerated
sound field which has comparatively more presence and a
more expansive feeling from the front 3 channels (front L,
front R, and center speakers} than that of ordinary stereo
regeneration. DOLBY 3CH LOGIC can be used with stereo
sources not encaded with DOLBY SURROUND.

(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
@ PHANTON-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.

lf the rear speakers are positioned at an extreme distance
from the front and center speakers, the surround level
becomes unabie to adjust and the surround effect will not
be fully achieved.
NOTES:
@ To 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.
@ 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.
