1. Connect your left and right rear surround speakers using speaker wire (not supplied).
2. Set the volume control to low.
3. Plug the AC power cord into the nearest wall outlet.
4. Make sure the transmitter is either in standby mode or powered on before turning the
receiver on.
The red LED will be illuminated on both units. The green LED on the receiver will flash
indicating it is searching for the transmitter signal and flicker until it finds a clear signal from
the transmitter, at which time the receiver’s LED glows solid green.
5. If you have a clear signal, adjust the volume control on the receiver so the audio level
coming from your rear surround speakers is balanced with the rest of your system.
6. If there is noise or distortion of the sound, you will need to adjust the antenna and the
transmitter input level.

DJUSTING THE ANTENNAS
The transmitter and receiver are provided with diversity antennas that fold up or down and
rotate through a horizontal range of 180 degrees for flawless audio reception and maximum
positioning options, enabling either or both the transmitter and receiver to be positioned
vertically or horizontally. The receiver has two antennas to maximize reception.
• Make sure that the flat side of the antennas on both the transmitter and receiver are facing
toward each other.
• The maximum transmission range (up to 30 feet) is achieved when there is a clear line of
sight between the transmitter and receiver antennas.
• You may wish to position the antennas so they face the ceiling at a 45 degree angle,
reflecting the transmitter signals to the receiver.

The input level is located on the back panel of the transmitter which can be used to adjust either
the line input or speaker input to the transmitter. The input level balances low level input signals
between the audio source and the transmitter. If there is distortion from your surround speakers
when you raise the main volume of your system, the input level should be adjusted down. If the
input level is set too low, the surround speakers will not get enough power to raise the volume to
a desired level.
1. Set the front speaker volume level to slightly higher than desired to establish a proper
output signal level for your rear speaker output.
