Connecting Your Speakers

Enjoying 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. You can enjoy DVDs featuring DTS and Dolby Digital. With analog and digital TV, you can enjoy Dolby Pro Logic IIx and Onkyo’s own DSP surround listening modes.

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 equally spaced from the TV. Angle them inward slightly 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. For movies it’s used mainly for dialog.

Position it close to your TV 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) chan-
nel. 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 position. In gen-
eral, a good bass sound can be obtained	Corner
by installing the subwoofer in a front cor-
ner, or at one-third the way along the wall,
as shown.
Tip: To find the best position for your sub-
woofer, while playing a movie or some	1/3 wall
music with good bass, experiment by plac-
	length
ing your subwoofer at various positions
within the room, and choose the one that
provides the most satisfying results.

Surround back left and right speakers

These speakers are necessary to enjoy Dolby Digital EX, DTS-ES Matrix, DTS-ES Discrete. They enhance the realism of surround sound and improve sound local- ization behind the listener. Posi- tion them behind the listener about 2–3 feet (60–100 cm) above ear level.

*While speaker set B is on, these speakers output no sound.

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 equally spaced from the listener.

Speaker Configuration

For the best surround-sound experience, you should connect seven speakers and a powered subwoofer. The following table shows which channels you should use based on the number of speakers that you have.

*If you’re using only one surround back speaker, connect it to the left (L) SURROUND BACK SPEAKERS terminals.

No matter how many speakers you use, a powered sub- woofer is recommended for a really powerful and solid bass.

Before using the AV receiver, you must do the automatic speaker setup (see page 35).
