1. Connect receiver to 12V 1000mA DC adapter
2. Connect one end of a 1/4” TRS to TRS cable to the receiver’s UNBALANCED AUDIO OUTPUT (MIX) and
the other end to a mixer or power amplifier. If you are using the BALANCED AUDIO OUTPUT use an XLR
cable or XLR to 1/4” TRS cable
3. Unscrew the cover handle of the microphone counter-clockwise to check to see if there are batteries. If
