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 1/8-inch stereo mini-jack/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 the transmission of high-performance, full-spectrum 
sound to remote locations, wirelessly. 
Like all wireless devices, the WEM-1 wireless speaker’s 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 
www.jbl.com, for further information or assistance.
