Hooking Up and Setting Up the Speaker System
Multi Channel Surround Setup
p 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 that
you set your sub woofer’s cut off frequency as high as
possible.
p Front speaker distance (FRONT)
Initial setting : 5.0 meter
Set the distance from your listening position to the front
(left or right) speaker (A on page 16).
• Front speaker distance can be set in 0.1 meter (1 foot)
steps from 1.0 to 12.0 meters (3 to 40 feet).
• If both speakers are not placed an equal distance from
your listening position, set the distance to the closest
speaker.
p Center speaker distance (CENTER)
Initial setting : 5.0 meter
Set the distance from your listening position to the center
speaker.
• Center speaker distance can be set in 0.1 meter (1 foot)
steps from a distance equal to the front speaker distance
(A on page 16) to a distance 1.5 meters (5 feet) closer to
your listening position (B on page 16).
• Do not place the center speaker farther away from your
listening position than the front speakers.
p Rear speaker distance (REAR)
Initial setting : 3.5 meter
Set the distance from your listening position to the rear
(left or right) speaker.
• Rear speaker distance can be set in 0.1 meter (1 foot)
steps from a distance equal to the front speaker distance
(A on page 16) to a distance 4.5 meters (15 feet) closer
to your listening position (C on page 16).
• 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
speaker.
p Rear speaker height (REAR HGT.)*
Initial setting : LOW
This parameter lets you specify the height of your rear
speakers for proper implementation of the Digital Cinema
Sound surround modes in the “VIRTUAL” sound fields.
Refer to the illustration below.
• Select “LOW” if the location of your rear speakers
corresponds to section A.
• Select “HIGH” if the location of your rear speakers
corresponds to section B.
This setting only affects the surround modes in the
“VIRTUAL” sound fields.
* These parameters are not available when “Rear speaker
size (REAR)“ is set to “NO”.

About the rear speaker position (SIDE, 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 environment has many variables,
such as wall reflections, and you may obtain better results using
“BEHIND” 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
play back 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 from the front
speakers. If you are not sure which sounds best, select
“BEHIND” and then use the speaker distance parameter and
speaker level adjustments to obtain proper balance.
