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 the Powered Subwoofers
Using a suitable cable, connect the AV receiver’s
SW1 PRE OUT
,
SW2 PRE OUT
to an input on
your powered subwoofer, as shown. If your sub-
woofer is unpowered and you’re using an external
amplifier, connect the
SW1 PRE OUT
,
SW2
PRE OUT
to an input on the amp.
You can connect the powered subwoofer with each
jacks respectively. Level and distance can be set
individually for each output. If you use one sub-
woofer, connect it to
SW1 PRE OUT
.
Bi-amping the Front Speakers
The
FRONT L/R
and
SURR BACK/ZONE 3 L/R
terminal
posts can be used with front speakers and surround back speak-
ers respectively, or bi-amped to provide separate tweeter and
woofer feeds for a pair of front speakers that support bi-amping,
providing improved bass and treble performance.
• When bi-amping is used, the AV receiver is able to drive up to
a 7.2 speaker system in the main room.
• For bi-amping, the
FRONT L/R
terminal posts connect to the
front speakers’ woofer terminals; the
SURR BACK/ZONE 3
L/R
terminal posts connect to the front speakers’ tweeter ter-
minals.
• Once you’ve completed the bi-amping connections shown
below and turned on the AV receiver, you must set the
“
Speakers Type(Front)
” setting to “
Bi-Amp
” to enable
bi-amping (

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.
