User manual JBL LX300

[. . . ] The loudspeakers are weatherresistant and may be used either indoors or outdoors, such as in a patio area. As noted below, when using the speakers outdoors, we recommend mounting them under an overhang, such as roof eaves, for added protection. Because they are resistant to moisture, the speakers are also appropriate for mounting in a bathroom, although not inside a bathtub or shower stall. More than 6 ­ 8 feet For home theater applications: 0-2 ft. Although these loudspeakers are designed as a mirrored pair, the decision as to which one is left or right will depend on the amount of space left between them. A wider stereo image is presented with the tweeter/midrange array outboard, and a tighter image is presented with the array inboard. This placement provides a wide spread in sound, supplemented by the center channel speaker. WALL-MOUNTING Do not attempt to mount these speakers on a ceiling, on the underside of roof eaves or in a shower stall. [. . . ] The LX300 loudspeakers may be positioned on the wall either horizontally or vertically. The grille logo on each speaker may be rotated depending on how the speaker is positioned. Gently pull the logo away from the grille slightly, rotate it to the desired position, and let go. When mounted vertically, the tweeter array may be positioned either up or down, depending on the height of the placement. If the speakers will be above ear level, the tweeter array should be positioned down, preferably no more than two feet above ear level. If the speakers will be mounted very low, it may be best to position the tweeter array upward so that it will be no more than two feet below ear level. The enclosures are specially designed to angle the speakers toward the listener when mounted flush against the wall. When mounting the speakers outdoors, we recommend that you place them under an overhang, such as roof eaves, for added protection, and that you use two of the supplied special angle-mount screws per speaker, which angle the speakers downward at a greater-than-usual angle, facilitating water drainage. NOTE: When using the enclosed angle-mount screws, always use the top two screw locations appropriate for the specific mounting orientation of your LX300. Referring to the enclosed installation template, screw locations (1) and (2) are to be used when mounting the LX300 horizontally so that these locations are on top. It is important to connect both speakers identically: (+) on the speaker to (+) on the amplifier and (­) on the speaker to (­) on the amplifier. Wiring "out of phase" results in thin sound, weak bass and a poor stereo image. With the advent of multichannel surround European CE certification, these holes are blocked with plastic inserts at the point of manufacture. Do not remove these inserts if you are using the product in an area covered by European CE certification. TROUBLESHOOTING If there is no sound from any of the speakers: · Check that receiver/amplifier is on and that a source is playing. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other. If the system plays at low volumes but shuts off as volume is increased: · Check all wires and connections between receiver/amplifier and speakers. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is no sound coming from one speaker: · Check the "Balance" control on your receiver/amplifier. · Check all wires and connections between receiver/amplifier and speakers. [. . . ] · Check all wires and connections between receiver/amplifier and speakers. Make sure no wires are touching other wires or terminals and creating a short circuit. · In Dolby* Digital or DTS® modes, make sure that the receiver/ processor is configured so that the speaker in question is enabled. · Turn off all electronics and switch the speaker in question with one of the other speakers that is working correctly.
