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, your
AC electrical 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.

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 if your source contains RCA-type preamp outputs for the
front/main channels or a 1/8-inch stereo single-pin output. 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 a 1/8-inch single-pin 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 1/8-inch single-pin 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 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 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

2 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 half-way.
Turn on your Control 2.4G transmitter and active speaker. Once the lower LED
on the active speaker illuminates 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 half-way
up with audio receivers or A/V receivers, at about three-quarters 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 the volume

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.
