Safety Information

• This package contains only the wireless microphone system. An additional audio device (speaker or amplifier) is required to output sound.
• The output volume depends on the power output of your speakers. We do not recommend using this microphone with speakers less than 15 watts.
• Do not use the microphone too close to the receiver to avoid sound interference.
• Keep the receiver away from metal objects or any digital devices (such as computers, mobile phones, etc.) to avoid potential sources of interference.
• Do not cover the microphone head with your hand, as this may damage it or affect performance.
• For optimal performance and to reduce plosives, we recommend using a foam cover on the microphone.

Operating Instructions

Once setup is complete, you can begin using your microphone system:

• Volume Adjustment: Use the volume knobs on the receiver (Vol-A for Microphone A, Vol-B for Microphone B) to adjust the individual microphone volumes.
• Microphone Usage: Hold the microphone approximately 2-6 inches from your mouth for optimal sound pickup.
• Freedom of Movement: The wireless design allows you to move freely within the transmission range (up to 60m, ideally 80m).
• Sound Quality: The system is equipped with a sound filter and high-sensitivity sound head to effectively filter excessive external noise and capture strong, clear audio.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the receiver and microphones. Do not use liquid cleaners or abrasive materials.
• Storage: When not in use for extended periods, remove batteries from the microphones and store the system in a cool, dry place.
• Battery Life: The microphones offer a long battery life (typically 2 to 8 hours). Replace batteries when performance degrades.

Troubleshooting

How to Avoid Interference:

• Microphone Proximity: Do not use the microphone too close to the receiver to prevent sound interference (feedback).
• Receiver Placement: Keep the receiver away from metal objects or any digital devices (e.g., computers, mobile phones) to avoid potential interference sources.
• Microphone Handling: Do not cover the microphone head with your hand, as this can cause damage or affect sound quality.
• Low Volume/No Sound:
  • Ensure the receiver is powered on and connected correctly to your amplifier/speaker.
  • Check if the microphones are turned on and have fresh batteries.
  • Verify the volume levels on both the receiver and your amplifier/speaker.
  • Confirm that the amplifier/speaker has sufficient power (recommended 15 watts or more).
• Distorted Sound:
  • Reduce the microphone volume on the receiver or the amplifier.
  • Ensure the microphone is not too close to your mouth or the speaker.
  • Check for strong electromagnetic interference from other devices nearby.
