- Using the supplied RCA cable and adaptor, connect the 'LINE IN' RCA inputs on the transmitter to the subwoofer output (LFE or Sub Out) of your audio source (e.g., AV receiver, pre-amplifier). Ensure correct polarity (red to red, white to white if applicable, or use the single LFE connection).
- Place the transmitter in a location that allows for a clear line of sight to the receiver, ideally within 30 meters.
