CONNECTIONS
NOTES: For the sake of simplicity, throughout this manual the term source is used when describing connections and operation. This would apply to any device 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 setup instructions for that application. Audio sources that can be used in this application may be an A/V receiver or audio receiver, a portable audio player, or a computer featuring a sound card. First, determine whether your source contains RCA-type preamp outputs for the front/main channels or only speaker wire outputs. On an A/V or audio receiver, the preamp outputs are usually indicated by RCA-type jacks on the back of the receiver labeled as pre-out (please refer to your sources owners manual to confirm whether it includes preamp outputs). If your source includes these RCA-type outputs, follow the steps in Connection Option A. If your source features only speaker wire outputs, follow steps in Connection Option B. If your receiver does not feature either type of outputs for the front/main channels, it cannot be used with the WEM-1. Connection Option A Connecting 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 the transmitter module 7, as shown in Figure 1.

Source Front/Main/Second Room Preamp Outputs
Right Speaker Left Speaker

Figure 2.

Step 4. Plug the transmitter module and receiver module into the wall outlets, using the power supply and correct power cord. Make sure the antennas 4E are extended upward. Step 5. Make sure the ID Code setting on the transmitter 6 is 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 sources owners manual for specific instructions). When connected properly, the LED on the front of the receiver should 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 will then also light in solid green. This LED will light in orange if the local input on the receiver is selected (see page 5 under Local Input for more details). Connection Option B Connecting 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 receivers speaker outputs and the inputs on the transmitter module 8, as shown in 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. Step 3. Connect speaker wire (not included) to the push terminals on the receiver module A and to the connectors on your speakers, as shown in Figure 2. Please note that speaker wire features some form of a polarity indicator to help distinguish its two conductors. Use this polarity indicator 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 ().

Step 3. Connect the speaker wire to the push terminals on the receiver module A and the terminals on the rear of your speakers, as shown in Figure 4. Please note that the speaker wire features a polarity indicator to help distinguish its two conductors. Use this polarity indicator 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 ().
When 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 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 sources volume control about a third of the way up, and activate the speaker-level-adjustment test tone. Make sure that the WEM-1 transmitter and receiver are on, both of the speakers are connected, and there is RF lock (i.e., the LED on the receiver is solid green). Using the remote control 1 and 2, adjust the volume level of the WEM-1 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 WEM-1 remote control for volume settings. You will be increasing and decreasing the output level for the entire surround sound system using your A/V sources 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 Input

The JBL On Air WEM-1 receiver module also includes a local input on the front of the receiver module. This input allows you to hook up a portable audio player directly to the WEM-1, wherever you may happen to be. For example, you could have 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, switching between the two different sources.

Figure 4.

Step 4. Plug the transmitter module and receiver module into the wall outlets, using the correct power supplies and power cords. Make sure the antennas 4E are extended upward. Make sure the ID Code setting on the transmitter 6 is 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 receiver should 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 will then light in solid green. This LED will light orange if the local input on the receiver is selected (see the Local Input section for more details).
To connect a portable audio player to the receiver module, simply connect the preamp-out, line-out or headphone jack to the line-in on the front of the receiver module 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 3 on the remote control.

ID Codes

In the unlikely event that you experience interference when operating the system, or if you have more than one set of WEM-1 transmitters and receivers in operation, you may change the channel in which the system operates. On both the transmitter and receiver modules, there is a four-position ID Code selector 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 the system to function correctly. You can also set up a maximum of two receiver modules to be receiving from the same transmitter by setting the channel selector 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, or reception and operating range in one or both units may be degraded.

Adjusting the Volume

Depending on the type of connection and the specific source that you are using, the volume setting on your audio receiver may affect the sound output level of your WEM-1. To check whether the output from your source is volumedependent, turn the volume level on your audio receiver to approximately halfway. Turn on your WEM-1 transmitter and receiver modules. Once the LED on the receiver module lights in solid green, indicating that RF lock has been achieved, verify that there is sound output from the speakers. Then increase and decrease the volume control on your receiver and observe whether this affects the sound output from your speakers. If it does not, then the volume control 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 volume setting on your source does affect the output from the WEM-1, then you will need to always keep your sources volume control at about halfway up with audio receivers or A/V receivers. From this point on, you will use the remote control included with the WEM-1 to adjust Volume 1 and 2.

EQ Switch

The 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 the loudspeakers indicated. If your specific loudspeaker is not listed below, simply set the EQ Switch C to position 1.

* Blinking stops when unit reaches minimum or maximum volume setting Subwoofer Output The JBL On Air WEM-1 includes a subwoofer output 9 on the receiver module. This output allows you to feed the low-frequency sounds to a separate powered subwoofer. 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 9 on 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). Please note that this output is full-range and not filtered or low-passed. Make sure that your powered subwoofer features a low-pass crossover network and that this crossover 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-frequency information from your subwoofer.
