Tips
• a)–c) correspond to the following Dolby Pro Logic

b) PHANTOM
c) 3 STEREO
• The "LARGE" and "SMALL" settings for each
speaker determine whether the internal sound
processor will cut the bass signal from that channel.
When the bass is cut from a channel, the bass
redirection circuitry sends the corresponding bass
frequencies to the sub woofer or other "LARGE"
speakers.
b)
However, since bass sounds have a certain amount of
directionality, it is best not to cut them, if possible.
Therefore, even when using small speakers, you can
set them to "LARGE" if you want to output the bass
frequencies from that speaker. On the other hand, if
you are using a large speaker, but prefer not to have
bass frequencies output from that speaker, set it to
"SMALL".
If the overall sound level is lower than you prefer, set
all speakers to "LARGE". If there is not enough bass,
you can use the BASS parameter in the
EQUALIZER menu to boost the bass levels. To
adjust the bass, see page 37.
x FRONT DIST. X.X m (XX ft.)
(Front speaker distance)
Initial setting: 3.0 m (10 ft.)

meter to 7.0 meters (3 to 23 feet) in 0.1 meter (1 foot)
steps.
If both front speakers are not placed an equal distance
from your listening position, set the distance to the
closest speaker.
