Therefore, although it may result in a setting contrary
to the “Surround 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 surround speakers and
the sound of the front speakers. If you are not sure
which sounds best, select “PL. BEHD.” and then use
the speaker distance parameter and speaker level
adjustments to obtain proper balance.
Only when you use the speaker system
other than the supplied one, be sure to
set the following parameters.
For details on NORM. SP. (Normal Speaker), see
page 16.
x Front speaker size (
L
R
)
• If you connect large speakers that will
effectively reproduce bass frequencies, select
“LARGE”. Normally, select “LARGE”.
• If the sound is distorted, or you feel a lack of
surround effects when using multi channel
surround sound, select “SMALL” to activate
the bass redirection circuitry and output the
front channel bass frequencies from the sub
woofer.
• When the front speakers are set to “SMALL”,
the center and surround speakers are also
automatically set to “SMALL” (unless
previously set to “NO”).
x Surround speaker height (
SL
SR
HGT. XXX)*
This parameter lets you specify the height of
your surround speakers for proper
implementation of the Digital Cinema Sound
surround modes. Refer to the illustration below.
• Select “LOW” if the location of your surround
speakers corresponds to section A.
• Select “HIGH” if the location of your surround
speakers corresponds to section B.
* These parameters are not available when
“Surround speaker size (
SL
SR
)” is set to “NO”.
Tip
The surround speaker position parameter is designed
specifically for implementation of the Digital Cinema
Sound modes with virtual elements.
With the Digital Cinema Sound modes, speaker
position is not as critical as other modes. All modes
with virtual elements were designed under the
premise that the surround speaker would be located
behind the listening position, but presentation remains
fairly consistent even with the surround speakers
positioned at a rather wide angle. However, if the
speakers are pointing towards the listener from the
immediate left and right of the listening position, the
sound fields with virtual elements will not be
effective unless the surround speaker position
parameter is set to “PL. SIDE”.
Nevertheless, each listening environment has many
variables, like wall reflections, and you may obtain
better results using “PL. MID” and “PL. BEHD.” if
your speakers are located high above the listening
position, even if they are to the immediate left and
right.
