Speakers A and Speakers B allows you to have two speaker configurations of up to 7.1 speakers. Each configuration has 
its own pair of stereo front speakers and can use the same subwoofer, center, surround, and surround back speakers, as 
required. You could, for example, use Speakers A when watching a DVD movie with 7.1-channels surround sound and 
use Speakers B for serious music listening with a pair of stereo speakers and the subwoofer (2.1-channels).

The speakers are configured by using the “Speaker Settings” on page 51 and “Speaker Setup” on page 94.

Front Speakers A and front Speakers B can be wired normally, bi-amped, or bridged, but A and B cannot be bi-amped 
or bridged at the same time. For example, if front Speakers A are bridged, front Speakers B can only be wired normally. 
Similarly, if front Speakers B are bi-amped, Speakers A can only be wired normally. When bridging is used, the AV 
receiver can drive 2 speakers in the main room (2.1 speakers if you're using a powered subwoofer). When bi-amping is 
used, the AV receiver can drive up to 5.1 speakers in the main room. See pages 27–30 for more information.

The Speakers A and Speakers B configurations are selected by using the [SP A] and [SP B] buttons on the remote 
controller. Only one configuration can be selected at a time.

The versatility offered by the Speakers A and Speakers B configurations means you can configure the AV receiver to 
suit your exact requirements and application. Two typical applications are shown below.
