About Home Theater
Thanks to the AV receiver’s superb capabilities, you can enjoy surround sound with a real sense of movement in your
own home—just like being in a movie theater or concert hall. With DVDs you can enjoy DTS and Dolby Digital. With
analog or digital TV, you can enjoy Dolby Pro Logic IIx, DTS Neo:6, or Onkyo’s original DSP listening modes.
You can also enjoy THX Surround EX (THX-certified THX speaker system recommended).
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 equidistant 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 dis-
tinct and providing a full sound
image. In movies it’s used
mainly for dialog.
Position it close to your TV fac-
ing 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 position, the shape of your
listening room, and your listening posi-
tion. In general, a good bass sound can
be obtained by installing the subwoofer
in a front corner, or at one-third the width
of the wall, as shown.
Tip: To find the best position for your
subwoofer, while playing a movie or
some music with good bass, experiment
by placing your subwoofer at various
positions within the room, and choose
the one that provides the most satisfying
results.
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 to
3 feet (60 to 100 cm) above ear level. Ideally they should be equidis-
tant from the listener.
Surround back left and right speakers
These speakers are necessary to enjoy Dolby Digital
EX, DTS-ES Matrix, DTS-ES Discrete, THX Surround
EX, etc. They enhance the realism of surround sound
and improve sound localization behind the listener.
Position them behind the listener about 2 to 3 feet (60
to 100 cm) above ear level.
Front high left and right speakers
These speakers are necessary to enjoy Dolby Pro Logic IIz Height,
Audyssey Dynamic Surround Expansion™, etc.
They enhance significantly the spatial experience.
Position them at least 3.3 feet (100 cm) above the front left and
right speakers (and as high as possible). Although it is acceptable
to place left and right at an angle slightly wider than the front left
and right speakers.
