Connecting a Powered Subwoofer
Using a suitable cable, connect the AV receiver's SUB-
WOOFER PRE OUT jack to an input on your pow-
ered subwoofer, as shown. If your subwoofer is
unpowered and you're using an external amplifier, con-
nect the SUBWOOFER PRE OUT jack to an input
on the amp.
Bi-amping the Front Speakers
The FRONT L/R and SURR BACK OR FRONT
HIGH L/R terminal posts can be used with front speak-
ers and surround back speakers respectively, or bi-
amped to provide separate tweeter and woofer feeds for
a pair of front speakers that support bi-amping, provid-
ing 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.
• For bi-amping, the FRONT L/R terminal posts con-
nect to the front speakers' woofer terminals; the
SURR BACK OR FRONT HIGH 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 "Speakers Type" setting to "Bi-AMP" to
enable bi-amping (➔ 40).
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.
