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 (a) should be positioned so that their
arrows point toward the TV/screen, while the surround
back dipole speakers (b) should be positioned so that their
arrows point toward each other, as shown.

To find the best position for your subwoofer, while playing
a movie or some music with good bass, experiment by
placing your subwoofer at various positions within the
room, and choose the one that provides the most satisfying
results.
You can connect the powered subwoofer with two
SUBWOOFER PRE OUT jacks respectively.
The same signal is output from each jack.
Tip
• If your subwoofer is unpowered and you're using an external
amplifier, connect the subwoofer pre out jack to an input on the
amplifier.

Bi-amping the Front Speakers
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.
Bi-amping provides improved bass and treble performance.
When bi-amping is used, the AV receiver is able to drive
up to a 5.1 speaker system in the main room.
Once you've completed the bi-amping connections as
shown and turned on the AV receiver, you must set the
speaker setting to enable bi-amping (➔ page
