229 Dolby Surround Pro Logic II
Dolby Surround Pro Logic II is a further devel-
opment of the previous version of the system
and provides enhanced sound quality. The
improved sound is particularly apparent to
passengers in the rear seat.
Dolby Surround Pro Logic II, together with a
center speaker in the dashboard, offers you a
sound experience very close to a live perform-
ance. The normal left-right stereo channels are
divided to left-center-right. In addition, sur-
round sound is produced by the rear speakers.
This surround sound mirrors the ambience of a
concert hall.
NOTE
•
Dolby Surround Pro Logic II is opti-
mized for CD mode.
•
When listening to FM radio stations,
Dolby Surround Pro Logic II functions
best in areas with strong reception. If
reception is weak, selecting 2 or 3 -
channel stereo may provide better
sound quality.
•
3 channel stereo is recommended for
AM and FM broadcasts.
