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.  
Right Speaker  
Left Speaker  
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 source’s  
owner’s 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.  
Figure 2.  
Step 4.  
Connection Option A  
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.  
Connecting using the preamp outputs on your source:  
NOTE: Make sure the power is turned off on all components.  
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 source’s owner’s manual for specific  
instructions).  
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  
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 receiver’s speaker outputs and the inputs  
on the transmitter module 8, as shown in Figure 3.  
Receiver  
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 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 (–).  
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.  
When using the WEM-1 to power surround speakers in  
a home theater system:  
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 (–).  
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 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 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.  
Right Speaker  
Left Speaker  
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.  
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).  
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.  
To switch between the two sources, push the Input button 3 on the  
remote control.  
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).  
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 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 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.

Subwoofer Output  
Turn receiver module over and remove all four corner screws,  
as shown in Figure 6.  
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.  
Figure 6.  
Step 2.  
Attach the wall bracket to the left and right side, as shown in Figure 7.  
A Word About Wireless Products  
The JBL On Air WEM-1 utilizes advanced wireless transceivers operating in the  
2.4GHz frequency band. This is the same frequency band that is used for wireless  
home networks and high-quality cordless phones. It also allows the transmission of  
high-performance, full-spectrum sound to remote locations, wirelessly.  
Step 3.  
Reattach the four screws removed in Step 1 through the brackets into the  
receiver module, as shown in Figure 7.  
Like all wireless devices, the WEM-1 wireless speaker’s operating range may  
vary, depending upon variables such as building construction methods and  
materials, atmospheric conditions and other sources of interference. Please  
information or assistance.  
Wall-Mounting  
Adjustable wall brackets are included for the transmitter and receiver modules.  
The included brackets are for wall-mounting only; they are not to be used for  
ceiling-mounting. Ceiling-mounting of the WEM-1 transmitter and/or speakers  
is not recommended, regardless of bracket used.
