Impedance Selector Switch - Yamaha HTR-5170 Owner's Manual

Note on main speaker connections:
One or two speaker systems can be connected to this unit. If you
use only one speaker system, connect it to either the
SPEAKERS A or B terminals.
Note on a subwoofer connection:
You may wish to add a subwoofer to reinforce low frequencies or
to output low bass sound from the subwoofer channel when
reproducing discrete signals.
When using a subwoofer, connect the SUBWOOFER terminal of
this unit to the INPUT terminal of the subwoofer amplifier, and
connect the speaker terminals of the subwoofer amplifier to the
subwoofer.
With some subwoofers, including the Yamaha Active Servo
Processing Subwoofer System, the amplifier and subwoofer are
in the same unit. Such a subwoofer needs only the connection
between the SUBWOOFER terminal of this unit and the INPUT
terminal of the subwoofer.
(Refer to page 22 for details about the SUBWOOFER terminal.)
