Sony STR-DE725 - Manual (Page 14)

V About speaker sizes (LARGE and SMALL)
Internally, the LARGE and SMALL settings for each speaker
determine whether or not the internal sound processor will cut
the bass signal from that chatnnel. When the bass is cut from a
channel, the bass redirection circuitry sends the corresponding
bass frequencies to the sub woofer or other 'LARGE'' speaker.
However, since bass sounds have a certain amount of
directionality it best not to cut them, if possible. Therefore, even
when using small speakers, you canset them to LARGE " if you
want to output the bass frequencies from that speaker. On the
other hand, if you are using a large speaker, but prefer not to
have bass frequencies output from that spteaker. set it to
'SMALL".
If the overall sound level is lower than you prefer, set all speakers
to “LARGE". If there is not enough bass you can use the
equalizer to boost the bass levels. To adjust the equalizer, see
page 31.
■ Rear speaker position (REAR PL.)*
Initial setting: BEHIND
This parameter lets you specify the location of your rear
speakers for proper implementation of the Digital Cinema
Sound surround modes in the VIRTUAL 3D genre. Refer
to the illustration below.
• Select “SIDE” if the location of your rear speakers
corresponds to section O-
• Select “MIDDLE” if the location of your rear speakers
corresponds to section ©.
• Select "BEHIND” if the location of your rear speakers
corresponds to section 0.
This setting only eifects the surround modes in the
VIRTUAL 3D genre.
■ Rear speaker height (REAR HGT.)*
Initial setting: LOW
This parameter lets you spediy the height of your rear
speakers for proper implementation of the Digital Cinema
Sound surround modes in the VIRTUAL 3D genre. Refer
to the illustration below.
• Select “LOW" if the location of your rear speakers
corresponds to section O.
♦ Select "HIGH” if the location of your rear speakers
corresponds to section ©.
This setting only effects the surround modes in the
VIRTUAL 3D genre.
* These parameters are not available when “Rear speaker
size (REAR)“ is set to “NO”.
V About the rear speaker position (SIDE, MIDDLE, and BEHIND)
This setting is designed specifically for implementation of the
Digital Cinema Sound modes in the VIRTUAL 3D genre.
With the Digital Cinema Sound modes, speaker position is not as
critical as other modes. All of the modes in the VIRTUAL 3D
genre were designed under the premise that the rear speaker
would be located behind the listening position, but presentation
remains fairly consistent even with the rear speakers positioned
at a rather wide angie. However, if the speakers are pointing
toward the listener from the immediate left and right of the
listening position, the VIRTUAL 3D modes will not be effective
unless the rear speaker position parameter is set to "SIDE".
Nevertheless, each listening environment has many variables,
like wail reflections, and you may obtain better resuits 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
"Rear 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 rear speakers and the sound of 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.
