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 II and Onkyo’s own DSP surround listening modes.

Center speaker (SKC-750C)

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.

Front left and right speakers (SKF-750F)

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.

Subwoofer (SKW-750)

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 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-	Corner
woofer, while playing a movie or some
music with good bass, experiment by plac-
ing your subwoofer at various positions
within the room, and choose the one that
provides the most satisfying results.
If the subwoofer is placed on a hard floor
(wood, vinyl, tile, etc.) and playback is very
loud, the subwoofer's feet may damage the
flooring. To prevent this, place the supplied
pads underneath the sub-
woofer's feet. The pads
also provide a stable base
for the subwoofer.

Surround left and right speakers (SKM-750S)

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.

■Using Rubber Spacers with the Speakers

We recommend using the supplied rubber spacers to achieve the best possible sound from your speakers. The rubber spacers prevent the speakers from moving, provid- ing a more stable setup.
