a)
If you connect only one surround back speaker,
connect it to the SPEAKERS SURROUND
BACK/BI-AMP/FRONT B L terminals.
b)
If you are not using surround back speaker, and
you have an additional front speaker system,
connect the additional front speaker system to the
SPEAKERS SURROUND BACK/BI-AMP/
FRONT B terminals. Set "SB ASSIGN" to
"SPK B" in the SPEAKER menu (page 52).
You can select the front speaker system you want
to use with SPEAKERS on the front panel
(page 33).
c)
If you are not using surround back speakers, you
can connect the front speakers to the SPEAKERS
SURROUND BACK/BI-AMP/FRONT B
terminals using a bi-amplifier connection
(page 100).
Set "SB ASSIGN" to "BI-AMP" in the SPEAKER
menu (page 52).
d)
When you connect a subwoofer with an auto
standby function, turn off the function when
watching movies. If the auto standby function is
set to on, it turns to standby mode automatically
based on the level of the input signal to a
subwoofer, then sound may not be output.
Note
Before connecting the AC power cord (mains lead),
make sure that metalic wires of the speaker cords are
not touching each other between the SPEAKERS
terminals.
