Connecting Your Speakers
You can use two sets of speakers with the AV receiver: speaker set A and speaker set B.
Speaker set A should be installed in your main listening room and can be used with Dolby Digital and DTS surround
material. Each speaker must be positioned at a specific location in your listening room to get the best from surround
sound material. The following illustration shows the best positions for your surround-sound speakers. When speaker set
B is turned on, speaker set A is reduced to 2.1-channel playback. If the multichannel DVD input is selected, and speaker
set B is turned on, speaker set A is reduced to 2-channel playback.
Speaker set B can be installed in another room. Speakers can be positioned in the standard position for stereo speakers
or however you like.
Enjoying Home Theater
Front left and right speakers
These output the overall sound. Their role in a home theater is to provide a solid anchor for
the sound image. They should be positioned facing the listener at about ear level, and equi-
distant from the TV. Angle them inward so as to create a triangle, with the listener at the apex.
Center speaker
This speaker enhances the front left
and right speakers, making sound
movements distinct and providing a
full sound image. In movies it’s used
mainly for dialog.
Position it close to your TV (preferably
on top) facing forward at about ear
level, or at the same height as the
front left and right speakers.
Subwoofer
The subwoofer handles the bass sounds of
the LFE (Low-Frequency Effects) channel.
The volume and quality of the bass output
from your subwoofer will depend on its posi-
tion, the shape of your listening room, and
your listening position. In
general, a good bass sound
can be obtained by install-
ing the subwoofer in a front
corner, or at one-third the
width of the wall, as shown.
Surround back speaker
This speaker further enhances
the realism of surround sound
and improves sound localiza-
tion behind the listener. It’s
essential to enjoy certain lis-
tening modes (i.e., Dolby Digi-
tal EX and DTS-ES). Position
it behind the listener about 2–
3 feet (60–100 cm) above ear
level. Make sure that the lis-
tening position is within the
range of the speaker.
Surround left and right speakers
These speakers are used for precise sound
positioning and to add realistic ambience.
Position them at the sides of the listener, or
slightly behind, about 2–3 feet (60–100 cm)
above ear level. Ideally they should be equi-
distant from the listener.
