"_" About speakerdistances
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 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. (1 foot
corresponds to a 1 ms difference.)
Adjusting these parameters while listening to the sound often
results in much better surround sound. Give it a try!
Use the remote while seated in your listening position to
adjust the volume of each speaker.
Note
This receiver incorporates a new test tone with a frequency
centered at 800 Hz for easier speaker volume adjustment.
