PREPARATION
Speakers
A full complement of eight speakers is shown here but, naturally, everyone's home set up will vary. Simply connect
the speakers you have in the manner described below. The receiver will work with just two stereo speakers (called
"front" speakers in the diagram) but the receiver is designed to be used with at least three speakers.
One of the latest features of home theater is the use of SURROUND BACK speakers. These speakers add even
greater realism in movie sound effects and new discs with soundtracks in Dolby Digital or DTS incorporates these
channels. In order to be able to use these channels you must hook your SURROUND BACK speakers up to an
external amplifier and then connect that to the VSX-D909S, as shown in the diagram below. If you only have one
SURROUND BACK speaker hook it up to the SURROUND BACK L (SINGLE) terminal on the back of the receiver.
In general, make sure you connect the speaker on the right to the right terminal and the speaker on the left to the
left terminal. Also make sure the positive and negative (+/–) terminals on the receiver match those on the speakers.
Before making or changing the connections, switch off the power and disconnect the power cord from the AC
wall outlet.
The receiver has two speaker systems, A & B. A is the main system supporting the full complement of surround
sound speakers. If you switch on both A & B speaker systems, only front speakers and the subwoofer will be
audible. No sound will come from the center or surround speakers but multi channel sources will be down-mixed
to the active speakers so no sound will be lost. Similarly, if you choose just the B system you‘ll only hear the
front speakers connected to the B system and multi channel sources will be down-mixed to these two speakers.
