surround back speakers are also 
automatically set to “SMALL” (unless 
previously set to “NO”).
CENTER SP (Center speaker)
• 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.”
• SMALL
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.
• NO
If you have not connected a center speaker, 
select “NO,” the sound of the center channel 
will be output from the front speakers.
• MIX
We recommend you set “CENTER SP” to 
“MIX” to enjoy digital audio with high 
quality sound when you do not have a center 
speaker connected. Analog downmix works 
when you set “CENTER SP” to “MIX.” This 
setting is also effective to input signals from 
MULTI CHANNEL INPUT jacks.
SURROUND SP 
(Surround speaker)
The surround back speakers will be set to the 
same 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 
surround speakers to “LARGE.”
• SMALL
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 
surround channel bass frequencies from the 
sub woofer or other “LARGE” speakers.
• NO
If you have not connected surround 
speakers, select “NO.”
SUR BACK SP 
(Surround back speakers)
When the surround speakers are set to “NO,” 
the surround back speakers are also 
automatically set to “NO” and the setting 
cannot be changed.
• DUAL
If you connect two surround back speakers, 
select “DUAL.” The sound will be output to 
a maximum of 7.1 channels.
• SINGLE
If you connect only one surround back 
speaker, select “SINGLE.” The sound will 
be output to a maximum of 6.1 channels.
• NO
If you have not connected surround back 
speakers, select “NO.”
• ZONE 2 
If you use the surround back speaker in zone 
2, select “ZONE 2.” When you select 
“ZONE 2,” the input to the SURROUND 
BACK jacks of the MULTI CHANNEL 
INPUT is invalid (page 24).
• BI-AMP
If you connect front speakers in a bi-
amplifier configuration, select “BI-AMP” 
(page 101).
Note
When “SUR BACK SP” is set to “BI-AMP,” even if 
“CENTER SP” is set to “MIX,” the setting will be 
ignored, so set “CENTER SP” to “NO.”
Tip
The “LARGE” and “SMALL” settings for each 
speaker determine whether 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” 
speakers.
However, since bass sound has a certain amount of 
directionality, it is best not to cut them, if possible.
