About speaker distances
This receiver allows you to input the speaker position in terms of
distance. However, it is not possible to set the center speaker
farther away than the front speakers. Also, the center speaker can
not be set more that 5 feet (1.5 meters) closer than the front
speakers.
Likewise, the surround and surround back speakers cannot be set
farther away from the listening position than the front speakers.
And they can be no more than 15 feet (4.5 meters) closer.
This is because incorrect speaker placement is not conducive to
enjoy the 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 3~6 feet (1~2 m)
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 soundstage.
Adjusting these parameters while listening to the sound often
results in much better surround sound. Give it a try!
x Sub woofer phase polarity (S.W PHASE)
Initial setting : NORMAL
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)
Initial setting : feet (meter)
Lets you select either feet or meters as the unit of measure
for setting distances.
x Front speaker distance (FRONT XX.X)
Initial setting : 16 feet (5.0 meter)
Set the distance from your listening position to the front
(left or right) speaker (A on page 19).
x Center speaker distance (CENTER XX.X)
Initial setting : 16 feet (5.0 meter)
Set the distance from your listening position to the center
speaker. Center speaker distance should be set from a
distance equal to the front speaker distance (A on page
19) to a distance 5 feet (1.5 meters) closer to your listening
position (B 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 speaker distance (SURROUND XX.X)
Initial setting : 11 feet (3.5 meter)
Set the distance from your listening position to the
surround speaker. Surround speaker distance should be
set from a distance equal to the front speaker distance (A
on page 19) to a distance 15 feet (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
XX.X)
Initial setting : 11 feet (3.5 meter)
Set the distance from your listening position to the
surround back speaker. Surround back speaker distance
should be set from a distance equal to the front speaker
distance (A on page 19) to a distance 15 feet (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 XX.X)
Initial setting : 16 feet (5.0 meter)
Set the distance from your listening position to the sub
woofer.
