Bi-amping the Front Speakers

Connecting Your Speakers—Continued

The FRONT L/R and SURR BACK L/R terminal posts can be used with front speakers 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, 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 setting to Bi-Amp to enable bi- amping (see page 45).

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.

•Use only front speakers with an impedance of 8 ohms or higher for bi-amping. Failure to do so may seriously damage the AV receiver.
