Connecting the AV receiver
—Continued
The FRONT L/R and SURR BACK/ZONE 3 L/R termi-
nal posts can be used with front speakers and surround
back speakers respectively, or bi-amped to provide sepa-
rate tweeter and woofer feeds for a pair of front speakers
A that support bi-amping, providing improved bass and
treble performance.
• When bi-amping is used, surround back speakers can-
not be used.
• For bi-amping, the FRONT L/R terminal posts con-
nect 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 “Speakers Type(FrontA)” setting to “Bi-Amp”
to enable biamping (see page 57).
• 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 only be used with speakers that support
bi-amping. Refer to your speaker manual.
