Onkyo TX-NR1008 Using Dipole Speakers, Connecting Powered Subwoofers, Bi-ampingthe Front Speakers

Using Dipole Speakers

You can use dipole speakers for the surround and surround back speakers. Dipole speakers output the same sound in two directions.

Dipole speakers typically have an arrow printed on them to indicate how they should be positioned. The surround dipole speakers should be positioned so that their arrows point toward the TV/screen, while the surround back dipole speak- ers should be positioned so that their arrows point toward each other, as shown.

Connecting Powered Subwoofers

Using a suitable cable, connect the AV receiver’s SUBWOOFER PRE OUT jack to an input on your powered subwoofer, as shown. If your sub- woofer is unpowered and you’re using an external amplifier, connect the SUBWOOFER PRE OUT jack to an input on the amp.

You can connect the powered subwoofer with two SUBWOOFER PRE OUT jacks respectively. The same signal is output from each jack.

Bi-amping the Front Speakers

The FRONT L/R and SURR BACK L/R terminal posts can be used with front speakers and surround back speakers respec- tively, 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 a 7.1 speaker system in the main room.

•For bi-amping, the FRONT L/R terminal posts connect to the front speakers’ woofer terminals; the SURR BACK L/R ter- minal 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(Front)” setting to “Bi-Amp” to enable bi- amping (➔ 47).
