3. Setup
Follow these steps to set up your PROEL Eikon EKJMA wireless microphone system:
- Charge the Devices: Connect the USB-C charging cable to both the handheld transmitter and the receiver. Plug the USB-A end into a compatible 5V USB power source (not included). The built-in 3.7V/500mA lithium batteries require charging before first use. A full charge provides up to 5 hours of performance use.
- Connect the Receiver: Insert the EKJ&M compact receiver into the 6.35 mm jack input of your amplifier, mixer, or audio interface. Ensure it is securely seated.
- Power On: Press and hold the power button on both the handheld transmitter and the receiver until their respective displays or indicator lights illuminate.
- Automatic Pairing: The transmitter and receiver are designed to automatically pair upon power-on. The system utilizes a UHF 512 – 541.7 MHz frequency band with quartz locked modulation for stable connection.
- Volume Adjustment: Adjust the volume on your amplifier or mixer to a suitable level. The microphone itself does not have a volume control.

4. Operating Instructions
Once set up, the PROEL Eikon EKJMA system is ready for use:
- Usage: Hold the handheld microphone comfortably. The unidirectional polar pattern is optimized for capturing sound directly in front of the microphone, minimizing background noise.
- Wireless Range: The system offers up to 30 meters (98 feet) of wireless range, providing freedom of movement during performances. Maintain a clear line of sight between the transmitter and receiver for optimal signal stability.
- Battery Status: Monitor the battery indicator on the handheld transmitter to ensure sufficient power for your performance. Recharge as needed using the provided USB-C cable.
- Multiple Systems: Up to 6 EKJMA systems can be used simultaneously in the same location, offering flexibility for multiple wireless performers. Ensure each system operates on a distinct frequency if manual selection is available (refer to advanced settings if applicable, though EKJMA typically auto-pairs).
- Power Off: After use, press and hold the power button on both the transmitter and receiver to turn them off. This conserves battery life.
5. Maintenance
Proper care and maintenance will extend the life of your PROEL Eikon EKJMA system:
- Cleaning: Use a soft, dry cloth to clean the exterior of the microphone and receiver. Do not use liquid cleaners or solvents, as they may damage the components.
- Storage: When not in use, store the system in its vinyl zippered protective carrying case to prevent dust accumulation and physical damage. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: For optimal battery longevity, avoid fully discharging the batteries frequently. If storing for extended periods, charge the batteries to approximately 50% every few months.
- Avoid Moisture: Keep the microphone and receiver away from water and high humidity. These devices are not waterproof.
6. Troubleshooting
If you encounter issues with your PROEL Eikon EKJMA system, refer to the following common solutions:
- No Sound Output:
- Ensure both the transmitter and receiver are powered on.
- Check that the receiver is securely plugged into your amplifier/mixer.
- Verify the volume on your amplifier/mixer is turned up.
- Confirm both devices are charged.
- Intermittent Signal/Poor Sound Quality:
- Ensure the transmitter and receiver are within the 30-meter operating range.
- Minimize obstacles (walls, large metal objects) between the transmitter and receiver.
- Check for other wireless devices operating on similar frequencies that might cause interference.
- Ensure batteries are sufficiently charged.
- Devices Not Pairing:
- Turn both devices off and then on again to re-initiate the pairing process.
- Ensure they are in close proximity during power-on.
- Short Battery Life:
- Ensure the devices are fully charged before use.
- Battery performance may degrade over time with extensive use.
