2. Notes on discs

DVD (Digital Versatile Disc) offers fantastic audio and video, thanks to Dolby Digital sur-

round sound and MPEG-2 video compression technology. Now you can enjoy these realistic effects in the home, as if you were in a movie theater or concert hall.

V I D E O

DVD players and the discs are coded by region. These regional codes must match in order for the disc to play. If the codes do not match, the disc will not play. The Region Number for this player is given on the rear panel of the player.

(Your DVD player will only play DVDs that are labeled with identical region codes.)

Rear Speakers

•

Place these speakers behind your listening position.

•

If there isn't enough room, place these speakers so they face each other.

•

Place them about 60 to 90cm (2 to 3feet) above your ear, facing slightly downward.

Unlike the front and center speakers, the rear speakers are used to handle mainly sound effects and sound will not come from them all the time.

Subwoofer

•

The position of the subwoofer is not so critical. Place it anywhere you like.

Front Speakers

•

Place these speakers in front of your listening position, facing inwards (about 45°) toward you.

•

Place the speakers so that their tweeters will be at the same height as your ear.

•

Align the front face of the front speakers with the front face of the center speaker or place them slightly in front of the center speakers.

Center Speaker

•

It is best to install it at the same height as the front speakers.

•

You can also install it directly over or under the TV.

Position of the Home Theater

•

Place it on a stand, cabinet shelf, or under the TV stand.

Selecting the Listening Position

The listening position should be located about 2.5 to 3 times the distance of the TV's screen size away from the TV. Example: For 32" TVs 2~2.4m (6~8 feet)

For 55" TVs 3.5~4m (11~13 feet)

Do not let children play with or near the speakers. They could get hurt if a speaker falls.

•

When connecting the speaker wires to the speakers, make sure that the polarity (+/–) is correct.

Caution

•

If you place a speaker near your TV set, screen color may be distorted because of the magnetic field generated by the speaker. If this occurs, place the speaker away from your TV set.
