About Home Theater

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. With DVDs you can enjoy DTS and Dolby Digital. With analog and digital TV you can enjoy Dolby Pro Logic II or 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 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	Corner
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 sub- woofer, while playing a movie or some music with good bass, experiment by placing your subwoofer at various posi- tions within the room, and choose the one that provides the most satisfying results.

1/3 wall length

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 equidistant from the listener.
