Tip
The receiver allows you to input the speaker position
in terms of distance. However, it is not possible to set
the center speaker further than the front speakers.
Also, the center speaker cannot be set more that
1.5 meters closer than the front speakers.
Likewise, the surround and surround back speakers
can not be set farther away from the listening position
than the front speakers. And they can be no more than
4.5 meters closer.
This is because incorrect speaker placement is not
conducive to the enjoyment of surround sound.
Please note that, setting the speaker distance closer
than the actual location of the speakers will cause a
delay in the output of the sound from that speaker. In
other words, the speaker will sound like it is farther
away.
For example, setting the center speaker distance
12 meters closer than the actual speaker position will
create a fairly realistic sensation of being inside the
screen. If you cannot obtain a satisfactory surround
effect because the surround speakers are too close,
setting the surround speaker distance closer (shorter)
than the actual distance will create a larger sound
stage.
Adjusting these parameter while listening to the
sound often results in much better surround sound.
Give it a try!
x Sub woofer phase polarity (S.W
PHASE)
Set the sub woofer phase polarity. There is
usually no problem when the sub woofer phase
polarity is set to NORMAL. However,
depending on the type of front speakers, the
position of the sub woofer, and the cut-off
frequency of the sub woofer, setting the phase
polarity to REVERSE may produce better
bass. Besides bass reproduction, the richness
and tightness of the overall sound may also be
affected. While listening from the main
listening position, select the setting that best
suits your environment.
x Distance unit (DISTANCE UNIT)
Lets you select either feet or meters as the unit
of measure for setting distances.
x Surround speaker distance
(SURROUND)
Set the distance from your listening position to
the surround speakers. Surround speaker
distance should be set from a distance equal to
the front speaker distance (A on page 19) to a
distance 4.5 meters closer to your listening
position (C on page 19). When this range is
exceeded, the display blinks. If you make the
setting while the display blinks, you cannot
fully enjoy the surround effect.
x Surround back speaker distance
(SURR BACK)
Set the distance from your listening position to
the surround back speaker(s). Surround back
speaker distance should be set from a distance
equal to the front speaker distance (A on page
19) to a distance 4.5 meters closer to your
listening position (D on page 19). When this
range is exceeded, the display blinks. If you
make the setting while the display blinks, you
cannot fully enjoy the surround effect.
x Sub woofer distance (SUB WOOFER)
Set the distance from your listening position to
the sub woofer.
