Onkyo TX-NR905 - Bi-Amping Front Speakers a

27
Connecting Your Speakers —Continued
The FRONT L/R and SURR BACK L/R terminal posts
can be used with front Speakers A and surround back
speakers respectively, or bi-amped to provide separate
tweeter and woofer feeds for front Speakers A, providing
improved bass and treble performance.
• When bi-amping is used, the AV receiver is able to
drive up to 5.1 speakers in the main room.
•For bi-amping, the FRONT L/R terminal posts con-
nect to the front speakers’ tweeter terminals. And the
SURR BACK L/R terminal posts connect to the front
speakers’ woofer terminals.
• Once you’ve completed the bi-amping connections
shown below and turned on the AV receiver, you must
set the Speaker Type Front A setting to Bi-Amp to
enable bi-amping (see page 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 only be used with speakers that support
bi-amping. Refer to your speaker manual.
