OPERATION

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 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 1 and

2adjust 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 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 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 volume 1and 2.

Local Input

The JBL On Air Control 2.4G wireless speaker system also includes a local input 8 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 line-in 8 on the rear of the active speaker 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 3 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 7 on the rear of the active speaker. 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 active speaker, simply connect the sub- out 7on the active speaker to the line-in on the rear of the powered subwoofer using a 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.

*Only one stereo mini-jack/dual-RCA cable is included with the system. If you are following Application 2, Connection Option B, you will need to purchase this additional cable.

A Word About Wireless Products

The JBL On Air Control 2.4G wireless speaker system 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 JBL On Air Control 2.4G wireless speaker’s oper- ating range may vary depending upon variables such as building construction methods and materials, atmospheric conditions and other sources of interfer- ence.
