User manual JBL L220

[. . . ] Conventional loudspeakers are designed to treat all musical tracks equally, and many modern speakers are intended for use as part of a home theater. But when used with a compatible playback system, the KHM10 is designed to make even beginning singers sound great. Set up two KHM10 speakers for stereo imaging, and let the karaoke party begin! SPEAKER PLACEMENT In all cases, it is important to place the speaker with safety in mind. [. . . ] The speaker should be placed out of reach of young children and pets who might topple it, resulting in serious personal injury. All wires should be placed where they will not present a tripping hazard. If that is not possible, cover the wires completely and securely with duct tape. Place the speaker so that the tweeters (located in the upper portion of the two side panels) are at approximately ear height and aimed at the listening position. When two speakers are used, place them equidistant from the main listening position. The KHM10 monitor is videoshielded and can safely be placed near a television. The supplied self-adhesive rubber pads may be attached to the bottom corners of the speaker to protect your furniture. 0 0 ­ 2 ft. ­ 2 ft.

The trim controls enable you to compensate for various room conditions and vocal styles. Begin by turning the knobs in the center of each control as far counterclockwise as they will go. Adjust the trim controls so that the vocals are loud enough to be intelligible without being so loud as to be harsh or distorted. TROUBLESHOOTING If there is no sound from any of the speakers: · Check that receiver/amplifier is on and that a source is playing. · Review proper operation 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/ampli- fier and speakers. Make sure no wires are touching other wires or terminals and creating a short circuit. · Turn off all electronics and switch the speaker in question with one of the other speakers that is working correctly. Turn everything back on and determine whether the problem has followed the speaker, or has remained in the same channel. [. . . ] Turn everything back on and determine whether the problem has followed the speaker, or has remained in the same channel. If the problem is in the same channel, the source of the problem is most likely with your receiver/ amplifier, and you should consult the owner's manual for that product for further information. If the problem has followed the speaker, consult your dealer for further assistance or, if that is not possible, visit www. jbl. com for further information. If the system plays at low volumes but shuts off as volume is increased: · Check all wires and connections between receiver/ amplifier and speakers. [. . . ]
