About speaker distances
This unit 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 5 feet* (1.5 meters) closer than the front speakers.
Likewise, the rear speakers can not 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
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 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 rear speakers are too
close, setting the rear speaker distance closer (shorter) than the
actual distance will create a larger soundstage.
Adjusting these parameter while listening to the sound often
results in much better surround sound. Give it a try!
