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 Control 2.4G is designed for use in most countries worldwide,
depending upon local regulations. It includes 120V – 230V, 50/60Hz universal
power supplies for the transmitter module and the active speaker. While we
have included the two most commonly used AC cords with this product, yourACelectrical outlet may require the use of a different AC cord. For your safety,
it is essential to use an AC cord that is fully compatible with your local electri
cal system. When in doubt, please consult your local JBL dealer or distributor.  
The JBL On Air Control 2.4G may be connected to your source in several ways.
First, determine how you would like to use the JBL On Air Control 2.4G; then

Some computer sound cards feature preamp outputs in addition to or instead 
of speaker outputs. If your computer does feature preamp outputs, we 
recommend that they be used instead of speaker outputs. If you would like to
connect the computer to the JBL On Air Control 2.4G using preamp outputs on
your computer, follow the steps in Connection A.
Connection Option A
Connecting using the preamp outputs on your source:
NOTE: 
Make sure power is turned off on all components.
Step 1.
Connect the interconnect cable (included) to the left and right front/main 
preamp outputs or zone 2 outputs or REC outputs and the inputs on the
transmitter module 
,as shown in Figure 4.
Step 2.
Place the active speaker in the desired location in your home near an AC
outlet, as it needs to plug in to the wall.
Step 3.
Connect the speaker wire (included) to the push terminals on the active 
speaker 
and the push terminals on the rear of the passive speaker ,
as shown in Figure 3. Please note that the speaker wire supplied features a
polarity stripe to help distinguish its two conductors. Use this polarity stripe 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 (–). It
does not matter whether you use the striped conductor for connecting the
positive (+) terminals or the negative (–) terminals.
Step 4.
Plug the transmitter module and active speaker into the wall outlet,
using the correct power supply and power cord. Make sure the transmitter’s
antenna 
is extended upwards.
Step 5.
Make sure the ID code setting on the transmitter is set to the same setting as
that on the active speaker 
.See page 8 of this manual for more information on
ID codes. If necessary,configure your receiver to activate the preamp level out
puts for the main/front channels (consult your source’s owner’s manual for spe
cific instructions).
Figure 4.
Step 3.
Connect the speaker wire (included) to the push terminals on the active 
speaker 
and the push terminals on the rear of the passive speaker .
See Figure 3. Please note that the speaker wire supplied features a polarity
stripe to help distinguish its two conductors. Use this polarity stripe 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 (–). It does not
matter whether you use the striped conductor for connecting the positive (+)
terminals or the negative (–) terminals.
Step 4.
Plug the transmitter module and active speaker into the wall outlet,
using the correct power supply and power cord. Make sure the transmitter’s
antenna 
is extended upwards.
Step 5.
If necessary, configure your source to activate the preamp level outputs for
the surround/rear channels (consult your source’s owner’s manual for 
specific instructions).
Make sure the ID code setting on the transmitter 
is set to the same setting
as that on the active speaker 
.See page 8 of this manual for more information
on ID codes. When connected properly, the top LED on the front of the active
speaker should be green. When first plugged in, it will sometimes take several
seconds for the Control 2.4G active speaker to initialize and “wake up.“ Until
then, the top LED will be in red. Once the top LED is green, the bottom LED should
flash green until the transmitter and active speaker “lock in.” It will then also
light in solid green. This LED will light in orange if the local input on the active
speaker is selected (see page 8 under Local Input for more details).
Application 2
Adding speakers to remote locations around your home:
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 RCAtype preamp outputs for
the front/main channels or a 1/8inch stereo singlepin output. On an A/V or
audio receiver, the preamp outputs are usually indicated by RCAtype jacks on
the back of the receiver labeled as “preout” (please refer to your source’s
owner’s manual to confirm whether it includes preamp outputs). If your source
includes these RCAtype outputs, follow the steps in Connection Option A. 
If your source features a 1/8inch singlepin stereo jack, follow steps in
Connection Option B. If your receiver does not feature either type of preamp
outputs for the front/main channels, it cannot be used with Control 2.4G. Some
computer sound cards feature more than one 1/8inch singlepin jack. There 
is almost always one output that is called a speaker output. However, some
sound cards feature a preamp output or line output in addition to or instead
of speaker outputs. If your computer does feature preamp or line outputs, we
recommend that they be used instead of speaker outputs.

Adjusting the Volume
Application 1
Adding surround speakers to a home theater system: 
In this application, the output level of your Control 2.4G active speakers 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 speakerleveladjustment
test tone. Make sure that the Control 2.4G transmitter and speakers are on,
both of its speakers are connected, and there is RF lock (i.e., lower LED on
active speaker is solid green). Using the Control 2.4G remote control 
and
adjust the volume level of Control 2.4G 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 remote control of your Control 2.4G 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 Control
2.4G 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.
Application 2
Adding speakers to remote locations around your home:
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 Control 2.4G. To check whether the output from your source is volume
dependent, turn the volume level on your receiver to approximately halfway.
Turn on your Control 2.4G transmitter and active speaker. Once the lower LED
on the active speaker lights in solid green, indicating that RF lock has been
achieved, verify that there is sound output from the active speaker.Then
increase and decrease the volume control on your receiver and observe
whether this affects the sound output from your active 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 Control 2.4G. If changing
the volume setting on your source does affect the output from Control 2.4G,
then you will need to always keep your source’s volume control at about halfway
up with audio receivers or A/V receivers, at about threequarters of the way up
when using a computer,and at maximum if using a portable audio device. From
this point on, you will use the remote control included with the JBL On Air Control
2.4G wireless speaker system to adjust volume 
and .
Local Input
The JBL On Air Control 2.4G wireless speaker system also includes a local
input 
on the rear of the active speaker. This input allows you to hook up 
a portable audio player directly to the speaker wherever you may happen to
be. For example, you could have the system connected to your receiver as
described in Application 2, listening to a local FM station and then hook up
your portable music player to the local input and switch between the two 
different sources.
To connect a portable audio player to the active speaker,simply connect 
the preamp out, line out or headphone jack to the linein 
on the rear of 
the active speaker using a 1/8inch minijack – 1/8inch minijack 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 Control 2.4G transmitters and
receivers in operation, you may change the channel in which the system 
operates. On the transmitter module and the active speaker, there is a four
position “ID Code” selector. Simply set the selectors to one of the other 
positions. The transmitter and active speaker must be set to the same position
in order for the system to function correctly. You can also set up a maximum 
of two pairs of speakers to be receiving from the same transmitter by setting
the channel selector on the transmitter and both of the active speakers to the
same channel. Please note that the two active speakers need to be at least 
10m (33 feet) apart, or reception and operating range in one or both units may
be degraded.

Subwoofer Output
The JBL On Air Control 2.4G wireless speaker system includes a subwoofer
output 
on the rear of the active speaker.This output allows you to feed the
lowfrequency sounds to a separate powered subwoofer.A powered subwoofer
will deliver deeper bass response than is possible with speakers alone.
Toconnect a powered subwoofer to the active speaker,simply connect the sub
out 
on the active speaker to the linein on the rear of the powered subwoofer
using a 1/8inch stereo minijack/dualRCA cable (not included*). Please note 
that this output is fullrange and not filtered or lowpassed. Make sure that your
powered subwoofer features a lowpass 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.
* Only one stereo minijack/dualRCA cable is included with the system. If you
are following Application 2, Connection Option B, you will need to purchase
this additional cable.
