Sony STR-DN1000 Operating Instructions Manual page 19

a)
If you connect only one surround back speaker,
connect it to the SPEAKERS SURROUND
BACK/FRONT B/BI-AMP 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/FRONT B/
BI-AMP terminals. Set "SB Assign" to "Speaker
B" in the Speaker Settings menu (page 66).
You can select the front speaker system you want
to use with SPEAKERS on the front panel
(page 37).
c)
If you are not using surround back speakers, you
can connect the front speakers to the SPEAKERS
SURROUND BACK/FRONT B/BI-AMP
terminals using a bi-amplifier connection
(page 105).
Set "SB Assign" to "BI-AMP" in the Speaker
Settings menu (page 66).
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 metallic wires of the speaker cords
are not touching each other between the
SPEAKERS terminals.
