Multi Channel Surround Setup
W Surround speaker position (SURR POSl.)*
Initial setting : SIDE
This parameter lets you specify the location of your
surround speakers for proper implementation of the
Digital Cinema Sound surround modes in the
"VIRTUAL" sound fields. Refer to the illustration below.
l
Select "SIDE" if the location of your surround speakers
corresponds to section 0.
l
Select "MIDDLE" if the location of your surround
speakers corresponds to section 0.
l
Select "BEHIND"** if the location of your surround
speakers corresponds to section 0.
This setting only affects the surround modes in the
"VIRTUAL" sound fields.
* These parameters are not available when "Surround
speaker size" is set to "NO".
**This parameter is only available when "Surround back
speaker size" is set to "NO".
n Surround speaker height (SURR HEIGHT)*/
Surround back speaker height (SURR BACK
HGT.)***
Initial setting : LOW
This parameter lets you specify the height of your
surround and surround back speakers for proper
implementation of the Digital Cinema Sound surround
modes in the "VIRTUAL" sound fields. Refer to the
illustration below.
l
Select "LOW" if the location of your surround speakers
corresponds to section 0.
l
Select "HIGH" if the location of your surround speakers
corresponds to section 0.
This setting only affects the surround modes in the
"VIRTUAL" sound fields.
* These parameters are not available when "Surround
speaker size" is set to "NO".
*** This parameter is not available when "Surround back
speaker size" is set to "NO".
'c About the surround speaker position (SIDE, MIDDLE and
BEHIND)
This setting is designed specifically for implementation of the
Digital Cinema Sound modes in the "VIRTUAL" sound fields.
With the Digital Cinema Sound modes, speaker position is not as
critical as other modes. All of the modes in the "VIRTUAL"
sound fields were designed under the premise
that the surround
speaker 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 towards the listener from the immediate
left and right of the listening position, the "VIRTUAL" sound
fields will not be effective unless the surround speaker position
parameter is set to "SIDE".
Nevertheless, each listening environment has many variables,
such as wall reflections, and you may obtain better results using
"BEHIND" or "MIDDLE" 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
"Surround speaker position" explanation, we recommend that
you playback multi channel surround encoded software and
listen to the effect each setting has on your listening environment.
Choose 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 from
the front speakers. If you are not sure which sounds best, select
"BEHIND" and then use the speaker distance parameter and
speaker level adjustments to obtain proper balance.
