Connecting Your Speakers—Continued
Speaker Configuration
For 7.1-channel surround-sound playback, you need
seven speakers and a powered subwoofer.
The following table shows which channels you should
use based on the number of speakers you have.
Number of speakers:
Front left
Front right
Center
Surround left
Surround right
Surround back*
Surround back left
Surround back right
* If you're using only one surround back speaker, connect it to the
SURR BACK L terminals.
No matter how many speakers you use, a powered sub-
woofer is recommended for a powerful and solid bass.
To get the best from your surround-sound system, you
must set the speaker settings. You can do this automati-
cally (see page 61) or manually (see page 94).
Using Dipole Speakers
You can use dipole speakers for the surround left and
right and surround back left and right 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 left
and right dipole speakers should be positioned so that their
arrows point toward your TV or screen, while the surround
back left and right dipolar speakers should be positioned
so that their arrows point toward each other, as shown.

Connecting a Powered Subwoofer
Using a suitable cable, connect the AV receiver's SUB-
WOOFER PRE OUT to the input on your powered sub-
woofer. If your subwoofer is unpowered and you're
using an external amplifier, connect the SUBWOOFER
PRE OUT to the amp's input.
