User manual JBL L54

[. . . ] If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: · Reorient or relocate the receiving antenna. · Increase the separation between the equipment and receiver. · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. · Consult the dealer or an experienced radio/TV technician for help. [. . . ] Connect the speaker wire (included) to the push terminals on the active speaker 5 and the push terminals on the rear of the passive speaker 9. Please note that the speaker wire supplied features a polarity stripe to help distinguish its two conductors. Use this polarity stripe to ensure that you are connecting the positive (+) terminal on one speaker to the positive (+) terminal on the other, and the negative (­) to the negative (­). It does not matter whether you use the striped conductor for connecting the positive (+) terminals or the negative (­) terminals. Some computer sound cards feature preamp outputs in addition to or instead of speaker outputs. If your computer does feature preamp outputs, we recommend that they be used instead of speaker outputs. If you would like to connect the computer to the JBL On Air Control 2. 4G using preamp outputs on your computer, follow the steps in Connection A. Connection Option A Connecting using the preamp outputs on your source: NOTE: Make sure power is turned off on all components. Connect the interconnect cable (included) to the left and right front/main preamp outputs or zone 2 outputs or REC outputs and the inputs on the transmitter module D, as shown in Figure 4.

Plug the transmitter module B and active speaker 6 into the wall outlet, using the correct power supply and power cord. Make sure the transmitter's antenna A is extended upwards. If necessary, configure your source to activate the preamp level outputs for the surround/rear channels (consult your source's owner's manual for specific instructions). This LED will light in orange if the local input on the active speaker is selected (see page 8 under Local Input for more details). ID CODE 1234 R INPUT L Figure 5. Step 2. Place the active speaker in the desired location in your home near an AC outlet, as it needs to plug into the wall. Connect the speaker wire (included) to the push terminals on the active speaker 5 and the push terminals on the rear of the passive speaker 9, as shown in Figure 3. Please note that the speaker wire supplied features a polarity stripe to help distinguish its two conductors. Use this polarity stripe to ensure that you are connecting the positive (+) terminal on one speaker to the positive (+) terminal on the other, and the negative (­) to the negative (­). It does not matter whether you use the striped conductor for connecting the positive (+) terminals or the negative (­) terminals. 7 OPERATION Adjusting the Volume Application 1 Adding surround speakers to a home theater system: In this application, the output level of your Control 2. 4G active speakers will not only be dependent on the volume setting of your A/V source; it will also need to be properly adjusted after installation and before use in order to be able to work correctly with the other speakers in your multichannel surround system. To adjust the output level, turn your A/V source on, set your A/V source's volume control about a third of the way up, and activate the speaker-level-adjustment test tone. Make sure that the Control 2. 4G transmitter and speakers are on, both of its speakers are connected, and there is RF lock (i. e. , lower LED on active speaker is solid green). Using the Control 2. 4G remote control 1 and 2 adjust the volume level of Control 2. 4G until its output level is balanced with the rest of the speakers in your surround system. From this point on, you will not be using the remote control of your Control 2. 4G for volume settings. You will be increasing and decreasing the output level for the entire surround sound system using your A/V source's volume control. [. . . ] If the ball and shaft assembly is not backed out before tightening the nut, performing Step G below may dislodge the threaded insert in the speaker housing and permanently damage the speaker. Tighten the "knurled" nut (1) using a crescent wrench until it is firmly seated against the back of the speaker and has fully locked the ball/shaft (3) and the speaker cabinet together. Please note that once this nut is tightened, it may embed some marks on the back of the speaker where the attachment is made. However, these marks will be covered by the nut (1). [. . . ]
