User manual JBL N38 II

[. . . ] SPEAKER PLACEMENT Proper placement of the speakers is an important step in obtaining the most realistic soundstage possible. These recommendations are for the optimum placement of the loudspeakers. All of the Northridge Series loudspeakers referred to in this guide are video-shielded and can safely be placed near a television.

[. . . ] CAUTION: Floorstanding (tower) loudspeakers have a high center of gravity and may become unstable and tip over during earthquakes or if rocked, tipped or improperly positioned. If this is a concern, these speakers should be anchored to the wall behind them, using the same procedures and hardware customary for anchoring bookcases and wall units. Customer is responsible for proper installation and proper selection of hardware. TROUBLESHOOTING If there is no sound from any of the speakers: · Check that receiver/ amplifier is on and that a source is playing. 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. · Make sure no wires are touching other wires or terminals and creating a short circuit. · In Dolby* Digital or DTS® mode, 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. Turn everything back on, and determine whether the problem is in the same place, i. e. , the speaker that was working previously now has no sound and the speaker that was not working now sounds fine; or whether it has moved, i. e. , the speaker that was not working still has no sound and the speaker that was working is still fine. If the problem is in the same place, the source of the problem is most likely with your receiver or 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 our Web site at 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. · 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.
