Tip
Surround speaker position is designed specifically for
implementation of the Cinema Studio EX modes.
For other sound fields, speaker position is not so
critical. Those sound fields were designed under the
premise that the surround speakers would be located
behind the listening position, but presentation remains
fairly consistent even with the surround speakers
positioned at a rather wide angle. However, if the
speakers are pointing toward the listener from the
immediate left and right of the listening position, the
surround effects becomes unclear unless set to "SIDE".
Nevertheless, each listening environment has many
variables, like wall reflections, and you may obtain
better results using "BEHD" if your speakers are
located high above the listening position, even if they
are to the immediate left and right.
Therefore, although it may result in a setting contrary
to the above explanation, we recommend that you
playback multi channel surround encoded software and
select the setting that provides a good sense of
spaciousness and that best succeeds in forming a
cohesive space between the surround sound from the
surround speakers and the sound of the front speakers.
If you are not sure which sounds best, select "BEHD"
and then use the speaker distance parameter and
speaker level adjustments to obtain proper balance.
