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, SW2 PRE OUT to an input on your pow-
ered subwoofer, as shown. If your subwoofer is
unpowered and you’re using an external amplifier,
connect the SW1, 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 A
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 A that support bi-amp-
ing, providing improved bass and treble performance.
• When bi-amping is used, surround back speakers cannot be
used.
• For bi-amping, the FRONT L/R terminal posts connect to the
front speakers’ woofer terminals. And the SURR BACK/
ZONE 3 L/R terminal posts connect to the front speakers’
tweeter terminals.
• Once you’ve completed the bi-amping connections shown
below and turned on the AV receiver, you must set the “Speak-
ers Type(Front A)” setting to “Bi-Amp” to enable biamping
(
➔ 51).
• When front speakers A are biamped, front speakers B must be
wired normally or not used.
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.
