3. Setup Instructions
Follow these steps to set up your wireless microphone system:
- Unpack and Place Receiver: Carefully remove all components from the packaging. Place the UHF wireless receiver unit on a stable, flat surface, ensuring adequate ventilation.
- Connect Antennas: Screw the two included antennas onto the corresponding antenna ports on the rear of the receiver unit. Ensure they are securely tightened and positioned vertically for optimal signal reception.
- Power Connection: Connect the provided power adapter to the DC input on the rear of the receiver unit, then plug the adapter into a standard AC power outlet. Do not power on the unit yet.
- Audio Output Connection:
- Individual XLR Outputs: For separate control of each microphone, connect XLR cables from the "CH A" and "CH B" XLR outputs on the receiver to the corresponding inputs on your mixer or amplifier.
- Mixed 1/4'' Output: For a combined output of both microphones, connect a 1/4'' TS cable from the "MIX OUT" jack on the receiver to an input on your mixer or amplifier.
- Install Batteries in Transmitters: Open the battery compartment on each bodypack transmitter. Insert the provided batteries, observing the correct polarity (+/-). Close the compartment securely.
- Connect Microphones to Transmitters: Plug the 3.5mm connector of either a lapel microphone or a headset microphone into the input jack on each bodypack transmitter. Ensure a secure connection.
- Initial Power On:
- First, power on your mixer/amplifier, ensuring its volume is set to a low level.
- Next, power on the UHF wireless receiver unit using the power button on the front panel. The LCD display should illuminate.
- Finally, power on each bodypack transmitter. The transmitter's indicator light should turn on, and the receiver's display should show a signal for the corresponding channel.
- Frequency Synchronization (if needed): The system is typically pre-synced. If a microphone is not connecting, refer to the troubleshooting section for frequency synchronization steps.

4. Operation
Once the system is set up, follow these guidelines for optimal operation:
- Power On/Off Sequence: Always power on your audio mixer/amplifier first, then the receiver, and finally the transmitters. When powering off, reverse the sequence: transmitters first, then receiver, then mixer/amplifier. This prevents loud pops or damage to speakers.
- Volume Adjustment: Use the individual volume control knobs on the front panel of the receiver for Channel A and Channel B to adjust the output level of each microphone independently. Fine-tune the overall volume using your connected mixer or amplifier.
- LCD Display: The LCD display on the receiver shows the current operating frequency for each channel and signal strength indicators. Monitor these to ensure stable connection.
- Microphone Placement:
- Lapel Microphone: Clip the lapel microphone approximately 6-8 inches below the user's chin, centered on clothing, for clear voice pickup.
- Headset Microphone: Position the headset microphone boom approximately 1-2 inches from the corner of the user's mouth for direct sound capture and minimal ambient noise.
- Operating Range: The system operates within a specified UHF range. Maintain a clear line of sight between the transmitters and the receiver antennas for best performance. Obstacles like walls or large metal objects can reduce the effective range.
- Battery Life: Monitor the battery indicator on the bodypack transmitters (if available) or listen for signs of weakening signal, which may indicate low battery. Replace batteries promptly to avoid interruptions.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your wireless microphone system:
- Cleaning:
- Wipe the receiver and transmitters with a soft, dry cloth.
- For microphones, gently clean the mesh grille with a soft brush to remove any debris. Do not use liquid cleaners directly on the microphone capsule.
- Battery Care:
- Remove batteries from transmitters if the system will not be used for an extended period to prevent leakage and damage.
- Use high-quality alkaline or rechargeable batteries.
- Storage: Store the system in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity. If possible, use the original packaging or a padded case for transport and storage.
- Cable Management: Avoid sharp bends or kinks in cables. Store cables neatly to prevent damage.
