Connecting Your  Speakers
 
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. You can enjoy DVDs featuring Dolby Digital or DTS. 
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).

position
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. Posi-
tion them behind the listener about 2–3 feet 
(60–100 cm) above ear level.
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 lis-
tener, or slightly behind, about 2–3 feet 
(60–100 cm) above ear level. Ideally 
they should be equally spaced from the 
listener.
Center speaker
This speaker enhances the front left 
and right speakers, making sound 
movements distinct and providing a 
full sound image. For 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 installing the sub-
woofer in a front corner, or at one-third the way 
along the front wall, as shown.
Tip: To find the best position for your sub-
woofer, 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.
Front left and right speakers
These output the main 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 equally spaced from the TV. Angle them inward slightly so 
as to create a triangle, with the listener at the apex.
