Multi-Channel Surround Setup
i About speaker sizes (LARGE and SMALL)
hucrndlh’, the LAKGH cind SMALL settings tt>r ejeh speaker
determine whether or not the internal siumd processor will cut
the bass signal trom that channel. When the bass is cut trom a
channel, the bass redia'ction circuitr\’ sends the corresponding
bass trequencies to the sub woofer or other "LARCH” speaker.
Howex er, since bass^ounds ha\'e a certain amount of
directionality it best not to cut them, if possible. Therefore, e\'en
when using small speakers,
you can set them to "LARCH” if \’Ou
want to output the bass frequencies from that speaker. On the
other hand, if x’ou are using a large speaker, but prefer not to
ha\-e bass frequencies output from that speaker, set it to
"SMALL".
It the ox'erall smind lex’ol is lower than you prefer, set all speakers
to "L.ARCL". If there is not enough bass, \'ou can use the
equalizer to boost the bass leyels. To adjust the equalizer, see
page 34.
■ Rear speaker position (REAR PL.)’^
Initial sotting ; BEHIND
This parameter lets you specify the location of your rear
speakers for proper implementation of the Digital Cinema
Sounci surround modes in the VIRTUAL 3D genre. Refer
to the illustration below.
• Select "SIDE" if the location of your rear speakers
corresponds to section ©.
• Select "MIDDLE" if the location of your rear speakers
corresponds to section O-
• Select "BEHIND" if the location of your rear speakers
corresponds to section ©.
This setting only effects the surround modes in the
VIRTUAL 3D genre.
■ Rear speaker height (REAR HGT.)*
Initial setting ; LOW
This parameter lets vou specih' the height of vour rear
speakers for proper implementation of the Digital Cinema
Sound surround modes in the VIRTUAL 3D genre. Refer
to the illustration below.
• Select "LOW" if the location of vour rear speakers
corresponds to section ©.
• Select "HIGH" if the location of your rear speakers
corresponds to section O-
This setting only effects the surround modes in the
VIRTUAL 3D genre.
These parameters are not available when "Rear speaker
size (REAR}" is set to "NO",
? About the rear speaker position (SIDE, MIDDLE, and BEHIND)
This setting is designed specifically for implementation of the
Digital Cinema Sound modes in the VIRTUAL 3D genre.
With the Digital Cinema Sound modes, speaker position is not as
critical as other modes. All of the modes in the VIRTUAL 3D
genre w’ere designed under the premise that the rear speaker
would be located behind the listening position, but presentation
remains fairly consistent even with the rear speakers positioned
at a rather wide angle. Howeyer, if the speakers are pointing
toward the listener from the immediate left and right of the
listening position, the VIRTUAL 3D modes will not be cffectiye
unless the rear speaker position parameter is set to "SIDE".
Nevertheless, each listening environment has many variables,
like wall reflections, and you may obtain better results using
"BEHINL^” or "MIDDLE” if your speakers are located high above
the listening position, even if they are to the immediate left and
right.
Therefore, although it may result in a setting contrary to the
"Rear speaker position” explanation, we recommend that you
playback multi channel surround encoded software and listen to
the effect each setting has on your listening environment. Choose
the setting that provides a good sense of spaciousness and that
best succeeds in forming a cohesive space between the surround
sound from the rear speakers and the sound of the front speakers.
If you are not sure which sounds best, select "BEHIND" and them
use the speaker distance parameter and speaker level
adjustments to obtain proper balance.
