User manual JBL E150P

[. . . ] 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. If you are not sure of the type of power supply to your home, consult your product dealer or local power company. [. . . ] One technique that can help you find the ideal subwoofer location is to temporarily place the subwoofer near the main listening location. Then move around the room and determine where you hear the most pleasing bass performance. This would then be the ideal location for the subwoofer. SPEAKER CONNECTION When we designed the E150P and E250P powered subwoofers, our goal was to offer the user the best possible performance combined with the most flexible and complete installation options. Please look over the following three examples to determine which description best matches your system and follow the corresponding hookup instructions. To use the binding-post speaker terminals with bare wire, unscrew the collar until the hole through the center post is visible under the collar. Insert the bare end of the wire through the hole in the post, then screw the collar back down until the connection is tight. The holes in the center of the collars are intended for banana-type connectors. Speakers and electronics terminals have corresponding positive (+) and negative (­) terminals. It is important to connect both speakers identically: positive (+) on the speaker to positive (+) on the amplifier and negative (­) on the speaker to negative (­) on the amplifier. Wiring "out of phase" results in thin sound, weak bass and a poor stereo image. NOTE: The speaker-level connection method described on page 4 is not a preferred connection and should only be resorted to if your receiver/ processor does not have a line-level or subwoofer output. The customer is responsible for proper connections, and any damage to JBL or other equipment due to improper connections will not be covered by your JBL warranty. Consult with your JBL dealer or an audioinstallation expert if you have any questions about how to connect your subwoofer using the speaker-level inputs. 3 Analog Receiver/Processor ­ Speaker-Level Connections Use this installation method only with an analog receiver/ processor that does not have digital processing or bass management, and also does not have a subwoofer output or a volume-controlled preamp (line-) level output: Connect the speaker wires for both your main left and right speakers, and for the subwoofer, to the same speaker terminals on your receiver or amplifier. The wires may be joined by twisting together the bare ends of the two leads that will be connected to each terminal on the receiver/ amplifier, as shown in the diagram. This procedure should be done only four times (involving a total of eight barewire ends), and only for those wire ends that are being connected to the terminals on your receiver/amplifier. Do not twist together wire ends that are being inserted into terminals on any speaker or on the subwoofer. Do not twist together wire ends that will be used for any speakers other than the front left and right speakers or the subwoofer. Twist together the (+) leads at one end of the speaker wires that you have designated for the left front speaker and for To (+) terminal on left speaker To (+) terminal of left input on subwoofer the left high-level inputs on the subwoofer. [. . . ] · If you are using a Dolby Digital/DTS receiver or processor, make sure that the subwoofer adjustments on the receiver/processor are set up correctly. · Slowly turn the Level Control clockwise until you begin to hear the desired amount of bass. If you used the line-level inputs and there is no sound from the subwoofer: · Check that the receiver/ amplifier is on and a source is playing. [. . . ]
