Step 3.

Connect the speaker wire to the push terminals on the receiver module ￿ 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 (–).

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 ￿￿ are extended upward.

Make sure the ID Code setting on the transmitter ￿is set to the same setting as that on the receiver ￿. 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).

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 volume- dependent, 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 source’s 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 ￿and ￿.

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 source’s 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 ￿ and ￿, 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 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 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.

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 ￿ 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 ￿￿. 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.

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 ￿ to position 1.
