• Rear speaker height (REAR HEIGHT)*
Initial setting : LOW
This parameter lets you specify the height of your rear
speakers for pn_per implementation of the Digital Cinema
Sound surround modes in the "VIRTUAf" sound fields.
Refer to the illustration below.
• Select "LOW" if the location of your rear speakers
corresponds to secticm O.
• Select "HIGH" if the location of your rear speakers
corresponds to section Q.
This setting only effects the surround modes in the
"VIRTUAL" sound fields•
* These parameters are not available when "Rear speaker
size (REAR)" is set to "NO".
"_'i"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" sound fields.
With the Digital Cinema Sound modes, speaker position is not as
critical as other modes. All of the modes in the "VIRTUAL"
sound fields were 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. However, if the speakers are
pointing toward the listener from the immediate left and right of
the listening position, the "VIRTUAL" sound fields will not be
effective unless the rear speaker position parameter is set to
"SIDE".
Nevertheless, each listening envir_nnment has many variables,
like wall reflections, and you may obtain better results using
"BEHIND" 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 envi_nment. 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 f_nt speakers.
if you are not sure which sounds best, seiecl "BEHIND" and then
use the speaker distance parameter and speaker level
adjustments to obtain proper balance.
• Sub woofer selection (SUB WOOFER)
Initial setting
: YES
• If you connect a sub woofer, select "YES".
• If you do not connect a sub woofer, select "NO". This
activates the bass redirection circuitry and outputs the
LFE signals from other speakers.
• In order to take full advantage of the Dolby Digital
_,AC-3) bass redirection circuitry, we recommend setting
the sub woofer's cut (fff frequency as high as possible.
• Front speaker distance (FRONT)
Initial setting : 16 feet* (5.0 meter)
Set the distance from your listening position to the front
(left or right) speaker (_ on page 19).
• Front speaker distance can be set in 1 foot* (0.1 meter)
steps from 3 to 40 feet* (1.0 to 12.0 meters).
• If both speakers are not placed an equal distance from
your listening position, set the distance to the closest
speaken
* Models of area code U, CA only.
• Center speaker distance (CENTER)
Initial setting : 16 feet* (5.0 meter)
Set the distance from your listening position to the center
speaker.
• Center speaker distance can be set in 1 foot* (0.I meter)
steps from a distance equal to the front speaker distance
(_ on page 19) to a distance 5 feet* (1.5 meters) closer to
your listening position (0 on page 19).
• Do not place the center speaker farther away from your
listening position than the front speakers.
* Models of area code U, CA only.
• Rear speaker distance (REAR)
Initial setting : 11 feet* (3.5 meter)
Set the distance from your listening position to the rear
(left or right) speaker.
• Rear speaker distance can be set in 1 foot* (0.l meter)
steps from a distance equal to the front speaker distance
(O on page 19) to a distance 15 feet* (4.5 meters) closer
to your listening position (_ on page 19).
• Do not place the rear speakers farther away from your
listening position than the front speakers.
• If both speakers are not placed an equal distance from
your listening position, set the distance to the closest
speaken
* Models of area code U, CA only.
