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 Blu-ray Discs, you can enjoy DTS and Dolby Digital. With analog or digital TV, you can enjoy Dolby Pro Logic II, DTS Neo:6, or Onkyo’s original DSP listening modes.

aFront 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.

bCenter speaker

This speaker enhances the front speakers, making sound movements dis- tinct and providing a full sound image. In movies it’s used mainly for dia- log. Position it close to your TV facing forward at about ear level, or at the same height as the front speakers.

*While Speakers B is on, this speaker outputs no sound. c Surround 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 equidistant from the listener.

*While Speakers B is on, these speakers outputs no sound.

dSubwoofer

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 position. 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 satis- fying results.
