Multi Channel Surround Setup
pCenter speaker size (
C 
)
Initial setting : LARGE
• 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. *1
• If you do not connect the center speaker, select “NO”. The sound of the center channel will be output from the front speakers.*2
pRear speaker size (

)
Initial setting : LARGE
•If you connect large speakers that will effectively reproduce bass frequencies, select “LARGE”. Normally, select “LARGE”. However, if the front speakers are set to “SMALL”, you cannot set the rear speakers 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 rear channel bass frequencies from the sub woofer or other “LARGE” speakers.
•If you do not connect rear speakers, select “NO”.*3

zAbout 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”.
pRear 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”.
