5.3. Pairing Multiple Receivers to One Transmitter
The MELONARE PM-1 system supports connecting one transmitter to multiple receivers. Follow these steps to pair additional receivers:
- Power on one Transmitter (TX) and one Receiver (RX). They will automatically pair after a few seconds.
- Power off the Transmitter (TX).
- Long press the TX power button and the volume up (“+”) button simultaneously to turn it on. The blue RF indicator will flash rapidly, indicating it is ready to pair with a new RX.
- Turn on a new Receiver (RX) that you wish to pair.
- Briefly press the volume up (“+”) button on the Transmitter (TX) to pair it with the new Receiver (RX).
- The Transmitter (TX) is now connected to two receivers, enabling seamless audio distribution to multiple locations or devices. Repeat steps 3-5 for additional receivers.

5.5. Connecting Earphones
Plug your earphones into the Audio Output (3.5mm) on the Receiver (RX).
6. Operating Instructions
6.1. Power On/Off
Long press the Power Button on both the Transmitter (TX) and Receiver (RX) to turn them on or off.
6.2. MONO/STEREO Mode Selection
Use the MONO/STEREO Switch on both the Transmitter (TX) and Receiver (RX) to select your desired monitoring mode. Ensure both units are set to the same mode for optimal performance.
- Mono Mode: Provides identical audio to both earpieces, ideal for precise tonal feedback and clear focus in small gigs.
- Stereo Mode: Delivers separate audio to each earpiece, enhancing spatial awareness and detailed mix control for immersive monitoring in live performances.
6.3. Channel Selection
The Transmitter (TX) features a Channel Switch to cycle through 10 selectable frequencies. If you experience interference, try changing the channel on the Transmitter. All paired Receivers will automatically follow the Transmitter's channel.
6.4. Volume Control
Adjust the listening volume using the Volume Control buttons (+/-) on the Receiver (RX).
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the devices. Do not use liquid cleaners or solvents.
- Battery Care: To prolong battery life, avoid fully discharging the devices frequently. Recharge them regularly, especially if they will be stored for an extended period.
- Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures.
8. Troubleshooting
- No Sound:
- Ensure both TX and RX are powered on and charged.
- Verify that the TX and RX are properly paired (RF indicator should be solid blue).
- Check all audio cable connections.
- Adjust the volume on the RX.
- Interference/Poor Signal:
- Move closer to the Transmitter (TX). The maximum reliable range is 130 ft.
- Change the channel on the Transmitter (TX) using the Channel Switch.
- Ensure there are no large metal objects or other strong wireless signals (e.g., Wi-Fi routers, other 2.4G devices) directly between the TX and RX.
- UHF systems generally offer better penetration and stability than 2.4G systems, but extreme obstacles can still affect performance.
- Short Battery Life:
- Ensure devices are fully charged before use.
- Battery performance may degrade over time with repeated charging cycles.

10. User Tips
- Optimal Signal: UHF technology provides better signal penetration, making it more reliable for environments with minor obstructions compared to 2.4G systems.
- Mode Selection for Performance: Use Mono mode for critical tonal feedback in smaller settings, and Stereo mode for a more immersive and detailed mix control during live performances.
- Band Use: The ability to connect one transmitter to multiple receivers is excellent for bands or groups needing to monitor the same audio source simultaneously.
- Avoiding Interference: If you encounter signal drops or noise, try changing the channel on the transmitter. This can help find a clearer frequency in crowded wireless environments.
