NOTES: For the sake of simplicity, throughout this manual the term “source” is used when describing connections and operation. This would apply to anydevice such as an A/V receiver, audio component, computer or portable music player.The JBL On Air WEM-1 may be connected to your source in several ways.First, determine how you would like to use the WEM-1; then follow the setupinstructions for that application.Audio sources that can be used in this application may be an A/V receiver oraudio receiver, a portable audio player, or a computer featuring a sound card.First, determine whether your source contains RCA-type preamp outputs forthe front/main channels or only speaker wire outputs. On an A/V or audioreceiver, the preamp outputs are usually indicated by RCA-type jacks on the back of the receiver labeled as “pre-out” (please refer to your source’sowner’s manual to confirm whether it includes preamp outputs). If your sourceincludes these RCA-type outputs, follow the steps in Connection Option A. If your source features only speaker wire outputs, follow steps in ConnectionOption B. If your receiver does not feature either type of outputs for thefront/main channels, it cannot be used with the WEM-1. Connection Option AConnecting using the preamp outputs on your source:NOTE: Make sure the power is turned off on all components.Step 1.Connect the interconnect cable (included) to the left and right front/main preamp outputs, zone 2 outputs or REC outputs, and the inputs on thetransmitter module 7, as shown in Figure 1.Figure 1.Step 2.Place the receiver module in the desired location in your home near an AC outlet, as it needs to plug into the wall.Step 3.Connect speaker wire (not included) to the push terminals on the receivermodule Aand to the connectors on your speakers, as shown in Figure 2.Please note that speaker wire features some form of a polarity indicator tohelp distinguish its two conductors. Use this polarity indicator to ensure thatyou are connecting the positive (+) terminal on one speaker to the positive (+)terminal on the other, and the negative (–) to the negative (–). Figure 2.Step 4.Plug the transmitter module and receiver module into the wall outlets, usingthe power supply and correct power cord. Make sure the antennas 4E areextended upward.Step 5.Make sure the ID Code setting on the transmitter 6is set to the same setting as that on the receiver B. See page 5 for more information on ID codes. If necessary, configure your receiver to activate the preamp level outputs for the main/front channels (consult your source’s owner’s manual for specificinstructions).When connected properly, the LED on the front of the receiver should be redwhen first plugged in. When a button on the remote is pressed, the LED shouldflash green until the transmitter and receiver “lock in.” It will then also light insolid green. This LED will light in orange if the local input on the receiver isselected (see page 5 under “Local Input” for more details).Connection Option BConnecting using the speaker-level outputs from your receiver:NOTE: Make sure power is turned off on all components.Step 1.Connect the speaker wire to the receiver’s speaker outputs and the inputs on the transmitter module 8, as shown in Figure 3.Figure 3.Step 2.Place the receiver module in the desired location in your home near an AC outlet, as it needs to plug into the wall.ReceiverRight Speaker Left SpeakerRLSourceFront/Main/Second RoomPreamp OutputsCONNECTIONS4JBLP2744-WEM1-OM.qxd 6/25/08 11:47 AM Page 4
5When using the WEM-1 to power surround speakers in a home theater system: In this application, the output level of your WEM-1 will not only be dependenton the volume setting of your A/V source; it will also need to be properlyadjusted after installation and before use in order to be able to work correctlywith the other speakers in your multichannel surround system. To adjust theoutput level, turn your A/V source on, set your A/V source’s volume controlabout a third of the way up, and activate the speaker-level-adjustment testtone. Make sure that the WEM-1 transmitter and receiver are on, both of thespeakers are connected, and there is RF lock (i.e., the LED on the receiver issolid green). Using the remote control 1and 2, adjust the volume level ofthe WEM-1 until its output level is balanced with the rest of the speakers in yoursurround system. From this point on, you will not be using the WEM-1 remotecontrol for volume settings. You will be increasing and decreasing the output levelfor the entire surround sound system using your A/V source’s volume control.Please note that the WEM-1 will retain its volume setting when it is in standby,so there is no need to set its volume level every time the system is turned on.Local InputThe JBL On Air WEM-1 receiver module also includes a local input on the frontof the receiver module. This input allows you to hook up a portable audio playerdirectly to the WEM-1, wherever you may happen to be. For example, you couldhave the system connected to your audio receiver, listening to a local FM station,and then hook up your portable music player to the local input, switchingbetween the two different sources.To connect a portable audio player to the receiver module, simply connect thepreamp-out, line-out or headphone jack to the line-in on the front of the receivermodule using a 1/8-inch mini-jack – 1/8-inch mini-jack cable (not included).To switch between the two sources, push the Input button 3on the remote control.ID CodesIn the unlikely event that you experience interference when operating thesystem, or if you have more than one set of WEM-1 transmitters and receiversin operation, you may change the channel in which the system operates. Onboth the transmitter and receiver modules, there is a four-position ID Codeselector 6B. Simply set each of the selectors to one of the other positions.The transmitter and receiver must be set to the same position in order for thesystem to function correctly. You can also set up a maximum of two receivermodules to be receiving from the same transmitter by setting the channelselector on the transmitter and the receiver to the same channel. Please note that the two receiver modules need to be at least 10' (3m) apart, orreception and operating range in one or both units may be degraded.EQ SwitchThe WEM-1 offers a choice of EQ positions for use with select JBL speakers.This circuit optimizes the performance of the system when connected to theloudspeakers indicated. If your specific loudspeaker is not listed below, simplyset the EQ Switch Cto position 1.

Pleasenote that the speaker wire features a polarity indicator to help distinguish itstwo conductors. Use this polarity indicator to ensure that you are connectingthe positive (+) terminal on one speaker to the positive (+) terminal on theother, and the negative (–) to the negative (–). Figure 4.Step 4.Plug the transmitter module and receiver module into the wall outlets, usingthe correct power supplies and power cords. Make sure the antennas 4Eare extended upward.Make sure the ID Code setting on the transmitter 6is set to the same setting as that on the receiver B. See the “ID Codes” section for more information on ID codes. When connected properly, the LED on the front of the receivershould be red when first plugged in. When a button on the remote is pressed,the LED should flash green until the transmitter and receiver “lock in.” It willthen light in solid green. This LED will light orange if the local input on thereceiver is selected (see the “Local Input” section for more details).Adjusting the VolumeDepending on the type of connection and the specific source that you areusing, the volume setting on your audio receiver may affect the sound outputlevel of your WEM-1. To check whether the output from your source is volume-dependent, turn the volume level on your audio receiver to approximatelyhalfway. Turn on your WEM-1 transmitter and receiver modules. Once the LEDon the receiver module lights in solid green, indicating that RF lock has beenachieved, verify that there is sound output from the speakers. Then increaseand decrease the volume control on your receiver and observe whether thisaffects the sound output from your speakers. If it does not, then the volumecontrol on your source unit can be set at any position that you may desire, as it does not affect the performance of the WEM-1. If changing the volumesetting on your source does affect the output from the WEM-1, then you willneed to always keep your source’s volume control at about halfway up with audioreceivers or A/V receivers. From this point on, you will use the remote controlincluded with the WEM-1 to adjust Volume 1and 2.Right Speaker Left SpeakerJBLP2744-WEM1-OM.qxd 6/25/08 11:47 AM Page 5

A powered subwoofer will deliver deeper bass response than is possible with speakers alone.To connect a powered subwoofer to the receiver module, simply connect the Sub Out 9on the receiver module to the line-in on the rear of the powered subwoofer, using a 1/8-inch stereo mini-jack/RCA cable (not included). Pleasenote that this output is full-range and not filtered or low-passed. Make sure thatyour powered subwoofer features a low-pass crossover network and that thiscrossover is indeed selected. Do not use the LFE input on a powered subwoofer,as it is not filtered and you will be hearing a lot of undesirable higher-frequencyinformation from your subwoofer.A Word About Wireless ProductsThe JBL On Air WEM-1 utilizes advanced wireless transceivers operating in the2.4GHz frequency band. This is the same frequency band that is used for wirelesshome networks and high-quality cordless phones. It also allows the transmission ofhigh-performance, full-spectrum sound to remote locations, wirelessly.Like all wireless devices, the WEM-1 wireless speaker’s operating range mayvary, depending upon variables such as building construction methods and materials, atmospheric conditions and other sources of interference. Pleaseconsult your JBL dealer or distributor, or visit www.jbl.com, for further information or assistance.Wall-MountingAdjustable wall brackets are included for the transmitter and receiver modules.The included brackets are for wall-mounting only; they are not to be used forceiling-mounting.
