Using Dipole Speakers
You can use dipole speakers for the surround and surround
back speakers. Dipole speakers output the same sound in two
directions.
Dipole speakers typically have an arrow printed on them to
indicate how they should be positioned. The surround dipole
speakers should be positioned so that their arrows point
toward the TV/screen, while the surround back dipole speak-
ers should be positioned so that their arrows point toward
each other, as shown.

Connecting a Powered Subwoofer
Using a suitable cable, connect the AV receiver's
SUBWOOFER PRE OUT jack to an input on
your powered subwoofer, as shown. If your sub-
woofer is unpowered and you're using an external
amplifier, connect the SUBWOOFER PRE OUT
jack to an input on the amp.
You can connect the powered subwoofer with two
SUBWOOFER PRE OUT jacks respectively.
The same signal is output from each jack.
Bi-amping the Front Speakers
The FRONT L/R and SURR BACK OR FRONT
HIGH OR FRONT WIDE L/R terminal posts can be
used with front speakers and surround back speakers
respectively, or bi-amped to provide separate tweeter
and woofer feeds for a pair of front speakers that sup-
port bi-amping, providing improved bass and treble per-
formance.
• When bi-amping is used, the AV receiver is able to
drive up to a 5.1 speaker system in the main room.
• For bi-amping, the FRONT L/R terminal posts con-
nect to the front speakers' woofer terminals; the
SURR BACK OR FRONT HIGH OR FRONT
WIDE L/R terminal posts connect to the front speak-
ers' tweeter terminals.
• Once you've completed the bi-amping connections
shown below and turned on the AV receiver, you must
set the "Speakers Type" setting to "Bi-Amp" to
enable bi-amping (➔ 41).
Important:
• When making the bi-amping connections, be sure to remove the jumper bars that link the speakers' tweeter (high) and woofer (low)
terminals.
• Bi-amping can be used only with speakers that support bi-amping. Refer to your speaker manual.
