WARNING: The minimum load impedance that this
system can handle safely is 4 Ohms. Using lower
impedance loads can damage the unit and will void
your warranty.
Notes: For the sake of simplicity, throughout this manual we have
used the term “source” 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 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.
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 , 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
receiver module 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 (–).
CONNECTIONS
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  are extended upward.
Step 5.
Make sure the ID Code setting on the transmitter is set to the
same setting as that on the receiver . 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).
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 , 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.

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 (–).
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  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 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 half-way. Turn on your WEM-1
transmitter and receiver modules. Once the lower 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 audio
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 half-way
up with audio receivers or A/V receivers. From this point on, you will
use the remote control included with the WEM-1 wireless speaker
system to adjust the 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 you
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 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 3,5mm (1/8-inch) mini-jack –
3,5 mm (1/8-inch) mini-jack cable (not included).
To switch between the two sources, push the Input button on the
remote control.
ID Code
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 the the
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 3m (10 feet) 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.

Subwoofer Output
The JBL On Air WEM-1 includes a subwoofer output 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 on the receiver module to the line-in on the
rear of the powered subwoofer using a 3,5mm (1/8-inch) stereo mini-
jack – dual-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.
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 for the transmission of high-
performance, full-spectrum sound to remote locations, wirelessly.
Like all wireless devices, the WEM-1 operating range may vary
depending upon variables such as building construction methods
and materials, atmospheric conditions and other sources of
interference. Please consult your JBL dealer or distributor or visit us
at www.jbl.com for further information or assistance.
