5: Setting up the speakers
(continued)
x CENTER SP (Center speaker size)
• 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 (for all sources except MULTI CH 1/2)
If you did not connect a center speaker, select
"NO". The sound of the center channel will be
output from the front speakers (digital
downmix).
• MIX (for all sources except MULTI CH 1/2)
If you did not connect a center speaker but want
to downmix the center channel audio, select
"MIX" (page 26).
This is only active when the front, surround,
and surround back speakers are set to
"LARGE" (ANALOG DOWNMIX). When all
speakers are not set to "LARGE", the center
channel will be downmixed digitally (DIGITAL
DOWNMIX).
* When using MULTI CH 1/2 sources, the sound
of the center channel is output from the front
speakers if you select either "NO" or "MIX".
