is used when describing connections and operation. This would apply to any
device such as an A/V receiver, audio component, computer or portable

The JBL On Air WEM-1 may be connected to your source in several ways.
First, determine how you would like to use the WEM-1; then follow the setup
instructions for that application.

instructions for that application.
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 RCA-type preamp outputs for
the front/main channels or only speaker wire outputs. 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 only speaker wire outputs, follow steps in Connection
Option B. If your receiver does not feature either type of outputs for the
front/main channels, it cannot be used with the WEM-1.

Connection Option A
Connecting using the preamp outputs on your source:
NOTE: Make sure the power is turned off on all components.
Step 1.
Connect the interconnect cable (included) to the left and right front/main
preamp outputs, zone 2 outputs or REC outputs, and the inputs on the
transmitter module

Step 2.
Place the receiver module in the desired location in your home near an
AC outlet, as it needs to plug into the wall.

module
A and to the connectors on your speakers, as shown in Figure 2.
Please note that speaker wire features some form of a polarity indicator to
help distinguish its two conductors. Use this polarity indicator 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 (–).

necessary, configure your receiver to activate the preamp level outputs for
the main/front channels (consult your source’s owner’s manual for specific
instructions).
the main/front channels (consult your source’s owner’s manual for specific
instructions).
When connected properly, the LED on the front of the receiver should be red
when first plugged in. When a button on the remote is pressed, the LED should
flash green until the transmitter and receiver “lock in.” It will then also light in
solid green. This LED will light in orange if the local input on the receiver is
selected (see page 5 under “Local Input” for more details).
