About Speakers A and Speakers B
Speakers A and Speakers B allows you to have two speaker configurations of up to 5.1 speakers. (Speakers B cannot be
used if Speakers A is used for 7.1-channel playback.) 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 surround sound (5.1-channels) and use Speakers B for serious music
listening with a pair of stereo speakers and the subwoofer (2.1-channels).
Speakers A and Speakers B are set in the "Speaker Settings" on page 51 and configured in the Speaker Configuration
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. See pages 27–30 for more infor-
mation.
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.
