SUR SPK (Surround speakers)
• NO
If you have not connected surround 
speakers, select “NO”.
• 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 
subwoofer or other “LARGE” speakers.
• 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”.
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 subwoofer or other “LARGE” 
speakers.
However, since bass sounds have a certain amount 
of directionality, it is 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 tone to boost the bass levels. 
For details, see page 30.
FRT DIST. (Front speaker 
distance)
Lets you set the distance from your listening 
position to the front speakers (A). If both 
front speakers are not placed an equal distance 
from your listening position, set the distance to 
the closest speaker.
CNT DIST. (Center speaker 
distance)
Lets you set the distance from your listening 
position to the center speaker.
SL DIST. (Surround left speaker 
distance)
SR DIST. (Surround right 
speaker distance)
Lets you set the distance from your listening 
position to the surround speaker.
