Connect the transmitter to your A/V receiver, TV, or other audio source via RCA
Connect the receiver to a subwoofer, powered speaker, power amplifier, or other line level devices
Make sure both the transmitter and receiver are receiving power (through included wall adapter or USB source)
Wait a few seconds for the adapters to sync and you're ready
Up to three receivers can be paired to one transmitter to create a multi-room distributed audio system or for use with multiple powered subwoofers or speakers
