Install fresh batteries in the transmitters (refer to the section relative 
to the specifi c transmitter you are using).

Connect the AC power adapter to a wall outlet and to the back of 
the receiver.

Position the antennas 60° apart from each 
other as shown.

Connect one of the two outputs available at the back panel to the 
next stage in your system. Typically, use the ¼” output to connect to 
unbalanced equipment such as consumer level receivers, amplifi -
ers, and mixers. Connect to professional equipment using the XLR 
output (cable not included).

Making sure the volume of your speakers is off , turn on the receiver 
and the transmitters. The “CHANNEL” LED channel display turns 
on, indicating that the corresponding transmitter is paired with the 
receiver. Note that the number displayed (the channel number) is 
fi xed and cannot be adjusted. The “AUDIO” LED indicates the pres-
ence of an audio signal coming from the transmitter.

Turn the volume of your speakers back on and start increasing the 
volume of the transmitters until proper volume is achieved. The 
balance between the two microphones can be adjusted with the 
volume control trimmers in the back.

For better results, keep the transmitters at least 2’ away from the receiver 
but within the transmitter’s range (150’). Keep the transmitters in a direct 
line of sight with the receiver whenever possible.
Transmitters can be used one at a time or simultaneously.
Use the MUTE position on the transmitter switch to silence the micro-
phone without interrupting the pairing with the receiver, which could 
cause unwanted popping sounds.
