JBL Consumer Products THE KARAOKE PHENOMENON You've watched others, and now it's your turn to become a singing sensation. JBL helps you to sing your best with the introduction of the KHM10 karaoke monitor, designed to highlight your vocals as you sing along to your favorite popular tunes. 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. Always place the KHM10 on a sturdy shelf or credenza, making sure that no part of the speaker extends past the edge of the surface. 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.

It is solely the customer's responsibility to select proper hardware and to safely install the loudspeaker. If you are uncertain of your ability to safely mount the loudspeaker on a ceiling or wall, contact a professional custom installer for assistance. 5 ­ 6 5 ­ 6 ft. ft. (1.5­1.8m) (1.5­1.8m) The brackets should be capable of supporting a minimum weight of 20kg (44 lb), and should be compatible with the two 5/16"-18 threaded inserts on the top of each KHM10 speaker. Each screw should be 30mm (1-3/16") long. Note that the two threaded inserts are 101mm (4") apart. When mounting the KHM10 speaker from the ceiling, the bracket should be installed in a wood joist. Drywall alone is not strong enough to support the 0 ­ 2 ft. (0­0.6m) speaker, and may result in the speaker falling and seriously injuring someone. Likewise, when mounting the KHM10 speaker on a wall, the bracket should be installed in a wood stud to prevent falling. If the KHM10 speaker is being mounted on a brick or concrete wall, it is recommended that expansion anchor bolts be used. The KHM10 loudspeaker is not weather-resistant and should not be installed outdoors or in a moist area such as near a pool or hot tub.

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. This is the normal level of the associated highfrequency driver. Turning the knob clockwise decreases the driver's level. 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. · Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. · 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. 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. · Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is no (or low) bass output: · Make sure the polarities (+ and ­) of the left and right "Speaker Inputs" are connected properly. · Consider adding a powered subwoofer to your system.
