JBL Consumer Products INCLUDED Four satellites for left, right and surrounds. Wall-mount brackets. One center-channel speaker with adjustable support leg. Powered subwoofer. Two 20' speaker cables for connection from receiver to subwoofer. Two 15' speaker cables for connection from subwoofer to front speakers. Three 40' speaker cables for connection from receiver to left and right rear satellites and center speaker. 3 SPEAKER PLACEMENT Front Speakers Center-Channel Speaker Subwoofer 0-2 ft. Surround Speakers 5 ­ 6 ft. 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 two feet 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. Use the supplied support leg to aim it toward the listener by screwing the leg in to angle the speaker up, or unscrewing the leg slightly to angle the speaker down. The two 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 on a wall behind the listening position, facing forward. Experiment with their placement until you hear a diffuse, ambient sound accompanying the mainprogram material heard in the front speakers. 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, the best reproduction of bass will be heard when the subwoofer is placed in a corner along the same wall as the front speakers. [. . . ] · Make sure the subwoofer is plugged into an active electrical outlet. · Make sure the powered subwoofer is plugged in and is either in the "On" or "Auto" position. · In Dolby Digital or DTS modes, make sure your receiver/processor is configured so that the subwoofer and LFE output are enabled. If there is no sound from the surround speakers: · Check all wires and connections between receiver/ amplifier and speakers. [. . . ]
