Preparations

Speaker Placement

Where you place your speakers has a tremendous effect on how well your system sounds.

■ Placing the Main Speakers

Place the left and right Main speakers an equal distance from the main listening

position.

If you have a TV or video monitor in your system, the distance of each speaker

from each side of the TV or video monitor should be the same.

■ Placing the Center Speaker

If you have a TV or video monitor in your system, align the front face of the

Center speaker with the front face of the monitor. Place the speaker as close to the

monitor as possible, such as directly over or under the monitor. If you place the

speaker under the monitor, the Front Effect speakers can adjust the height of the

sound to correspond with the action on the screen (depending on the listener’s

position). If you have a projection screen in your system, place the Center speaker

under the screen. Be sure to align the speaker with the center of the screen.

■ Placing the Front Effect, Rear and Rear Center

Speakers

These speakers should be placed about 0.5~1m (1~3 feet) outside the Main

speakers and in the front of the room. They should be turned toward the main

listening position. Place the Rear speakers in the back of the room so they face the

main listening position. The Rear speakers can be placed farther apart than the

Front Effect speakers. The Front Effect and Rear speakers should be placed about

1.8m (6 feet) above the floor.

Once you begin listening to programs, continue to adjust the speaker placement

until you obtain a balanced sound from the Main speakers and the Front Effect

and Rear speakers.

■ When You Use a Projection Screen

Place the speakers as shown in the illustration.

The Main speakers should be placed about one-quarter of the way up from the

bottom of the screen.

Place the Center speaker in the center and directly under the screen. The Center

speaker provides precise dialogue localization.

When you use a projection screen with your system, the Front Effect speakers

provide better effect quality. The CINEMA-DSP sound field programs (see page

34) raise the sound from the Center speaker upward and provide natural sound

corresponding with the video images.

■ Placing the Subwoofers

Place the Front Subwoofer near the Main speakers. Turn it slightly toward the center of the room to reduce wall reflections.

If you use a Rear Subwoofer, place it behind the main listening position. The placement of the Rear Subwoofer is not critical because of

the ultralow frequencies of the sound being reproduced.

By adding a high quality Subwoofer to the speaker configurations shown on pages 21 and 22, you can enjoy more powerful and realistic

movie effects, even if your Main speakers are large.

Note:

• If you use different brands of speakers (with different tonal qualities) in your

configuration, the tone of a moving human voice and other types of sound may not

shift smoothly. We recommend that you use speakers from the same manufacturer or

speakers with the same tonal quality.

You can also adjust the output levels and equalization of your effect speakers using the

SET MENU (see page 37).

If you are using small speakers, the addition of a Subwoofer will reinforce the sound

effects of movies (see page 21).
