Tip
The receiver lets 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 than
1.5 meter closer from the front speakers.
Likewise, the surround speakers can not be set
further away from the listening position than the
front speakers. And they can be no more than
4.5 meter 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 further
away.
For example, setting the center speaker distance
1-2 meter 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 SW PHASE (Sub woofer phase
polarity)
Lets you set the sub woofer phase polarity.
• NORMAL
Normally, select "NORMAL".
• REVERSE
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.
