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 the Powered Subwoofers

Using a suitable cable, connect the AV receiver’s SW1, SW2 PRE OUT to an input on your pow- ered subwoofer, as shown. If your subwoofer is unpowered and you’re using an external amplifier, connect the SW1, SW2 PRE OUT to an input on the amp.

You can connect the powered subwoofer with each jacks respectively. Level and distance can be set individually for each output. If you use one sub- woofer, connect it to SW1 PRE OUT.

Bi-amping the Front Speakers A

The FRONT L/R and SURR BACK/ZONE 3 L/R terminal posts can be used with front speakers and surround back speak- ers respectively, or bi-amped to provide separate tweeter and woofer feeds for a pair of front speakers A that support bi-amp- ing, providing improved bass and treble performance.

•When bi-amping is used, surround back speakers cannot be used.

•For bi-amping, the FRONT L/R terminal posts connect 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 “Speak- ers Type(Front A)” setting to “Bi-Amp” to enable biamping (➔ 51).

•When front speakers A are biamped, front speakers B must be wired normally or not used.
