Hooking Up and Setting Up the Speaker System

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 channel. 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 can set 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 speaker, 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 bass/
treble to boost the bass levels. To adjust the bass/treble, see page
35.
p 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” sound fields.
Refer to the illustration below.
• Select “SIDE” if the location of your rear speakers
corresponds to section A.
• Select “BEHIND” if the location of your rear speakers
corresponds to section B.
This setting only effects the surround modes in the
“VIRTUAL” sound fields.
* These parameters are not available when “Rear speaker
size (REAR)” is set to “NO”.
p Center speaker size (
C
)
Initial setting : LARGE (STR-DE545/DE445)
SMALL (STR-SE501)
• If you connect a large speaker that will effectively
reproduce bass frequencies, select “LARGE”. Normally,
select “LARGE”. However, if the front speakers are set
to “SMALL”, you cannot set the center speaker to
“LARGE”.
• If the sound is distorted, or you feel a lack of surround
effects when using multi channel surround sound,
select “SMALL” to activate the bass redirection circuitry
and output the center channel bass frequencies from the
front speakers (if set to “LARGE”) or sub woofer. *

• If you do not connect the center speaker, select “NO”.
The sound of the center channel will be output from the
front speakers.*
