Now you can easily place your subwoofer anywhere in your home or use a pair of speakers on your patio or by your pool. Unpacking Verify that this box contains: one wireless audio transmitter one wireless audio receiver two 7.5 Volt AC adapters (wallwarts) two RCA audio cables Installation Connect the first RCA audio cable to the transmitter audio input and your audio source. If you are connecting to a single (mono) audio output, simply leave the second audio plug unconnected. Then connect the first wallwart to the transmitter power input. Next, connect the second RCA cable with the audio input of your active speakers, subwoofer or power amplifier. If you are connecting to a subwoofer, simply leave the second RCA plug unconnected. Finally, connect the second wallwart to the receiver power input. Pairing In order to stream audio, the receiver must first be paired with the audio transmitter. First, press the pairing button of the audio transmitter. The transmitter network status light will start flashing quickly.
