Onkyo TX-NR905 Bi-amping Front Speakers B, Zone 2 R negative terminal to the right

Connecting Your Speakers—Continued

Bi-amping Front Speakers B

The ZONE 2 L/R and SURR BACK L/R terminal posts can be used with front Speakers B and surround back speakers respectively, or bi-amped to provide separate tweeter and woofer feeds for front Speakers B, 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 ZONE 2 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 B setting to Bi-Amp to enable bi-amping (see page 51).

•When front Speakers B are biamped, front Speakers A must be wired normally.

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.
