User manual JBL 1500 ARRAY BG

[. . . ] Unplug this apparatus during lightning storms or when unused for long periods of time. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. Do not use attachments not recommended by the product manufacturer, as they may cause hazards. This product should be operated only from the type of power source indicated on the marking label. [. . . ] Notice the two threaded inserts on the angled face of the top and also the small L-bracket on the top. Immediately adjacent to the Lbracket is a recessed connector which will make the electrical connection for the horn module. Although the module can be installed by one person, it is easier if a second set of hands are available. Cradle the horn module with the opening along your forearm and, using your free hand, connect the plug coming from the bottom of the horn assembly into the jack on the top of the enclosure. The module will sit on top of the enclosure by itself, although it should always be steadied until fully mounted. Line up the two mounting holes on the lower lip of the front of the horn with those in the enclosure. It may be necessary to lift the horn slightly so that the bolts install smoothly. Once both bolts have been started, work them in all of the way, but do not tighten them securely just yet. Install the remaining short bolt in the hole at the bottom rear of the horn module. The final steps are to remove the backing from the logo badge and place it in the recess on the lower horn lip, and to use the rubber hole plug to hide the hole at the bottom rear of the horn module. Do not complete these steps until the system has been turned on and tested acoustically. Once the logo badge and rubber plug hole are installed, it is extremely difficult to remove them. 6 Step 9 Step 7 Step 11 Step 8 7 SPEAKER CONNECTIONS Subwoofer Controls and Connections (15 0 0 Array Only) ¡ Line-Level Input 2 3 0 1 4 5 6 7 TM Line-Level Output £ Power Indicator ¢ Subwoofer Level (Volume) Control Crossover Adjustment § Phase Switch ¶ LP/LFE Selector · On/Off Auto Switch ª Power Switch Connection: If you have a Dolby® Digital or DTS® receiver/processor with a low-frequencyeffects (LFE) output, set LFE/LP switch to LFE. Many users have a tendency to set the subwoofer volume too loud, adhering to the belief that a subwoofer is there to produce lots of bass. A subwoofer is there to enhance bass, extending the response of the entire system so the bass can be felt as well as heard. However, overall balance must be maintained or the music will not sound natural. An experienced listener will set the volume of the subwoofer so its impact on bass response is always there but never obtrusive. Crossover Adjustments NOTE: This control will have no effect if the LP/LFE Selector Switch ¶ is set to "LFE. " If you have a Dolby Digital or DTS processor/receiver, the Crossover Frequency is set by the processor/receiver. Consult your owner's manual to learn how to view or change this setting. The Crossover Adjustment Control determines the highest frequency at which the subwoofer reproduces sounds. 9 If your main speakers can comfortably reproduce some low-frequency sounds, set this control to a lower frequency setting, between 50Hz and 100Hz. This will concentrate the subwoofer's efforts on the ultradeep bass sounds required by today's films and music. If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies, set the Crossover Adjustment Control to a higher setting, between 120Hz and 150Hz. [. . . ] · Adjust the Subwoofer Level Control ¢. If there is no sound from the surround speakers: · Check all wires and connections between the receiver/ amplifier and speaker. · If your receiver/processor is set in Dolby Pro Logic® mode, make sure the center speaker is not in phantom mode. · If your receiver/processor is set in Dolby Digital or DTS mode, make sure the receiver/ processor is configured so that the center speaker is enabled. · Check all wires and connections between receiver/ amplifier and speakers. · Review proper operation of your receiver/amplifier and its surround sound features.
