x SURR BACK SP (Surround back
speaker size)
When the surround speakers are set to “NO”,
the surround back speakers are also
automatically set to “NO” and the setting
cannot be changed.
• 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 surround back
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
surround back channel bass frequencies from
the front speakers (if set to “LARGE”) or sub
woofer.
• NO
If you did not connect a surround back speaker,
select “NO”.
Tip
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” speakers.
However, since bass has 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 equalizer to boost the bass levels. To
adjust the equalizer, see page 45.
x SURR BACK L/R (7.1 channel/
6.1 channel switching)
• YES
If you connect two surround back speakers,
select “YES”. The sound will be output to a
maximum of 7.1 channels.
• NO
If you connect only one surround back speaker,
select “NO”. The sound will be output to a
maximum of 6.1 channels.
x SUB WOOFER (Sub woofer selection)
• YES
If you connect a sub woofer, select “YES”.
• NO
If you did not connect a sub woofer, select
“NO”. The sound of the sub woofer will be
output from the front speakers.
In the following cases, analog downmix
function is used for the sub woofer channel
audio.
– When using MULTI CH 1/MULTI CH 2
sources
– When the front and surround speakers are set
to “LARGE”, the surround back speakers are
set to “LARGE” or “NO”, and the center
speaker is set to the settings other than
“SMALL” for the digital sources.
In other cases, digital downmix function is used
for the sub woofer channel audio.
This activates the bass redirection circuitry and
outputs the LFE signals from other speakers.
Tip
In order to take full advantage of the Dolby Digital
bass redirection circuitry, we recommend setting the
