SURROUND SPEAKERS
� Single surround back speaker

may be used with 6.1 receivers and processors.

Alternate placement for surround speakers when only 5.1 channels are used; required placement for surround back speakers in 7.1-channel systems.

The front speakers should be placed the same distance from each other as they are from the listening position. They should be placed at about the same height from the floor as the listeners� ears will be, or they may be angled toward the listeners. The center channel speaker should be placed slightly behind the front left and right speakers, and no more than 2 feet (0.6m) above or below the tweeters of the left and right speakers. It is often convenient to set the center speaker on top of the television set, as shown in the drawing. The JBL Cinema Sound speaker system may be used in 5.1-, 6.1- or 7.1-channel applications. In 5.1-channel applications, two of the surround speakers should be

placed slightly behind the listening position and, ideally, should face each other and be at a level higher than the listeners� ears. If that is not possible, they may be placed against a wall behind the listening position, facing forward. In 6.1-channel applications, two of the surround speakers should be placed in the side positions, and a single surround back speaker should be placed against the wall behind the listening position. In 7.1-channel applications, place two of the surround speakers in the side positions, and place the two surround back speakers against the rear wall. In Dolby® Digital and DTS® systems, it is best to aim all of the speakers (except the subwoofer) toward the listening position at or slightly above about ear-level height.

In systems where only analog surround processing (such as Dolby Pro Logic® II) is available, it may be preferable to aim the speakers straight out from the wall to obtain a more diffuse sound. The low-frequency material reproduced by the subwoofer is mostly omnidirectional, and this speaker may be placed in a convenient location in the room. However, bass reproduction will be maximized when the subwoofer is placed in a corner along the same wall as the front speakers. Experiment with subwoofer placement by temporarily placing the subwoofer in the listening position and moving around the room until the bass reproduction is best. Place the subwoofer in that location.
