NOTES: For the sake of simplicity, throughout this manual we have used theterm “source” when describing connections and operation. This would applyto any device such as an A/V receiver, audio component, computer or portablemusic 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 universalpower supplies for the transmitter module and the active speaker. While wehave included the two most commonly used AC cords with this product, yourAC 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.

The JBL On Air 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 follow the setup instructions for that application.

Application 1

Adding surround speakers to a home theater system. Continue reading the instructions for Application 1 below.

Application 2

Adding speakers to remote locations around your home.

Application 1

Adding surround speakers to a home theater system:

Determine if your source contains preamp outputs for rear/surround channels,usually indicated by RCA-type jacks on the back of the receiver labeled as “surround preout” (please refer to your source’s owner’s manual to confirmwhether it includes the preamp outputs). If your receiver includes these outputs, follow the steps below. If not, connection is not recommended.

NOTE: Make sure power is turned off on all components.

Step 1.

Connect the interconnect cable (included) to the left and right surround/rearpreamp outputs on the back of your source and the input on the transmittermodule , as shown in Figure 1.

Step 2.

Determine the location of the surround speakers.

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 toconnect the computer to the JBL On Air Control 2.4G using preamp outputs onyour computer, follow the steps in Connection A.

Connection Option A

Connecting using the preamp outputs on your source:

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 thetransmitter module , as shown in Figure 4.

Step 2.

Place the active speaker in the desired location in your home near an ACoutlet, 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 apolarity stripe to help distinguish its two conductors. Use this polarity stripe toensure that you are connecting the positive (+) terminal on one speaker to thepositive (+) terminal on the other, and the negative (–) to the negative (–). Itdoes not matter whether you use the striped conductor for connecting thepositive (+) 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’santenna is extended upwards.

Step 5.

Make sure the ID code setting on the transmitter is set to the same setting asthat on the active speaker . See Page 8 of this manual for more information onID 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).

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 polaritystripe to help distinguish its two conductors. Use this polarity stripe to ensurethat you are connecting the positive (+) terminal on one speaker to the positive(+) terminal on the other, and the negative (–) to the negative (–). It does notmatter 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’santenna is extended upwards.

Step 5.

If necessary, configure your source to activate the preamp level outputs forthe 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 settingas that on the active speaker . See Page 8 of this manual for more informationon ID codes. When connected properly, the top LED on the front of the activespeaker should be green. When first plugged in, it will sometimes take severalseconds for the Control 2.4G active speaker to initialize and “wake up.“ Untilthen, the top LED will be in red. Once the top LED is green, the bottom LED shouldflash green until the transmitter and active speaker “lock in.” It will then alsoilluminate in solid green. This LED will illuminate in orange if the local input onthe 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 oraudio receiver, a portable audio player, or a computer featuring a sound card.First, determine if your source contains RCA-type preamp outputs for thefront/main channels or a 1/8-inch stereo single-pin output. On an A/V or audioreceiver, the preamp outputs are usually indicated by RCA-type jacks on theback of the receiver labeled as “pre-out” (please refer to your source’sowner’s manual to confirm whether it includes preamp outputs). If your sourceincludes 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 inConnection Option B. If your receiver does not feature either type of preampoutputs for the front/main channels, it cannot be used with Control 2.4G. Somecomputer 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, somesound cards feature a preamp output or line output in addition to or insteadof speaker outputs. If your computer does feature preamp or line outputs, werecommend 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 notonly be dependent on the volume setting of your A/V source, it will also needto be properly adjusted after installation and before use in order to be able towork 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 volumecontrol about a third of the way up, and activate the speaker-level-adjustmenttest 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 onactive 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 withthe rest of the speakers in your surround system. From this point on, you willnot be using the remote control of your Control 2.4G for volume settings. Youwill be increasing and decreasing the output level for the entire surroundsound system using your A/V source’s volume control. Please note that Control2.4G will retain its volume setting when it is in standby, so there is no need toset 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 areusing, the volume setting on your receiver may affect the sound output level ofyour 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 LEDon the active speaker illuminates in solid green, indicating that RF lock hasbeen achieved, verify that there is sound output from the active speaker. Thenincrease and decrease the volume control on your receiver and observewhether 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 youmay desire as it does not affect the performance of Control 2.4G. If changingthe 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-wayup with audio receivers or A/V receivers, at about three-quarters of the way upwhen using a computer, and at maximum if using a portable audio device. Fromthis point on, you will use the remote control included with the JBL On Air Control2.4G wireless speaker system to adjust the volume and .

Local InputThe JBL On Air Control 2.4G wireless speaker system also includes a localinput 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 tobe. For example, you could have the system connected to your receiver asdescribed in Application 2, listening to a local FM station and then hook upyour portable music player to the local input and switch between the two different sources.

To connect portable audio player to the active speaker, simply connect thepreamp out, line out or headphone jack to the line-in on the rear of the activespeaker 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 CodeIn the unlikely event that you experience interference when operating thesystem, or if you have more than one set of Control 2.4G transmitters andreceivers 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 positionin 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 settingthe channel selector on the transmitter and both of the active speakers to thesame 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 maybe degraded.

Subwoofer Output

The JBL On Air Control 2.4G wireless speaker system includes a subwooferoutput on the rear of the active speaker. This output allows you to feed thelow-frequency sounds to a separate powered subwoofer. A powered subwooferwill deliver deeper bass response than is possible with speakers alone.

To connect a powered subwoofer to the active speaker, simply connect the sub-out on the active speaker to the line-in on the rear of the powered subwooferusing a 1/8-inch stereo mini-jack – dual-RCA cable (not included*). Please notethat this output is full range and not filtered or low-passed. Make sure that yourpowered subwoofer features a low-pass crossover network and that thiscrossover is indeed selected. Do not use the LFE input on a powered subwooferas it is not filtered and you will be hearing a lot of undesirable higher frequencyinformation from your subwoofer.

* One mini-jack – dual RCA cable is included with the system. If you are followingApplication 2, Connection Option B at left, you will need to purchase this cable.

A Word About Wireless ProductsThe JBL On Air Control 2.4G wireless speaker system utilizes advanced wireless transceivers operating in the 2.4GHz frequency band. This is the samefrequency band that is used for wireless home networks and high-qualitycordless phones. It also allows for the transmission of high-performance, full-spectrum sound to remote locations, wirelessly.

Like all wireless devices, the JBL On Air Control 2.4G wireless speaker’s oper-ating range may vary depending upon variables such as building constructionmethods and materials, atmospheric conditions and other sources of interfer-ence. Please consult your JBL dealer or distributor or visit us at www.jbl.comfor further information or assistance.
