3.1 Connecting the Receiver

1. Power Supply: Connect the included power adapter to the receiver's DC 12V input and then to a power outlet. The receiver can also be powered by a power bank.
2. Audio Output to Speaker/Amplifier:
   • Use the 6.35mm to 6.35mm cable to connect the receiver's 1/4" (6.35mm) Jack Out to your amplifier or mixer.
   • Alternatively, use the RCA to RCA cable to connect the receiver's RCA L+R Output to an active speaker or power amplifier.

   Important: This system requires an external speaker or sound system to output audio. It does not have a built-in speaker.

3. Audio Input (Optional):
   • Wired Input: Use the 3.5mm to 3.5mm audio cable to connect your TV, computer, mobile phone, or set-top box to the receiver's "INPUT" jack for background music.
   • Bluetooth Input: Power on the receiver. Activate Bluetooth on your mobile device (e.g., smartphone, tablet, computer) and search for the receiver's Bluetooth name (e.g., "X100"). Pair your device to stream background music wirelessly. The Bluetooth range is approximately 32.8 feet (10 meters).
