Setup Instructions
1. Battery Installation (Microphones)
- Unscrew the bottom part of each handheld microphone to reveal the battery compartment.
- Insert two fresh AA batteries into each microphone, ensuring correct polarity (+/-).
- Screw the bottom part back on securely.
2. Connecting the Receiver
The receiver requires connection to an audio mixer, amplifier, powered speaker, or PA system. It offers both balanced XLR outputs and an unbalanced 6.35mm (1/4'') mixed output.
- Connect the included power adapter to the receiver's DC 12V power interface and plug it into a power outlet.
- Attach the two antennas to the ANT-A and ANT-B interfaces on the rear of the receiver. Position them vertically for optimal signal reception.
- Choose your preferred audio output method:
- For individual microphone control (recommended): Use XLR cables (not included) to connect the MIC-A Output and MIC-B Output to separate input channels on your audio mixer or amplifier.
- For combined output: Use the included 6.35mm audio cable to connect the MIXED Output to a 6.35mm (1/4'') input on your audio device.
- Ensure your audio mixer/speaker/amplifier has an available AUX (3.5mm or 1/4'') or XLR input port.

Operating Instructions
1. Powering On/Off
- Receiver: Press the POWER button on the receiver's front panel. The display will illuminate.
- Microphones: Slide the ON/OFF switch on each microphone to the 'ON' position. The microphone's LCD will light up.
- To power off, reverse these steps.
2. Frequency Pairing and Selection
The system uses IR synchronization for easy pairing. It also features an auto-scan function to find the best available frequency.
- Automatic Pairing (Recommended):
- Ensure both the receiver and the microphone are powered on.
- On the receiver, long press the 'SET' (Frequency Pairing) button. The receiver will automatically scan for the best available frequency.
- While the receiver is scanning, align the microphone's IR window with the receiver's IR window (Frequency Infrared Pairing Window). The microphone will synchronize with the new frequency.
- Repeat for the second microphone.
- Manual Frequency Selection:
- On the receiver, use the 'Channel Selection' buttons (up/down arrows) to browse through the 200 available frequencies for the desired channel (A or B).
- Once a frequency is selected, short press the 'SET' button.
- Align the microphone's IR window with the receiver's IR window to synchronize.

3. Volume Adjustment
Use the 'Volume + or -' buttons on the receiver's front panel to adjust the output volume for each microphone channel independently. Adjust to a suitable level on your connected audio device as well.
4. Lock Function
The receiver features a lock function to prevent accidental changes to settings.
- To lock the receiver settings, long press the 'LOCK' button. The display will indicate that the settings are locked.
- To unlock, long press the 'LOCK' button again.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the receiver and microphones. Avoid using liquid cleaners or solvents.
- Battery Care: Remove batteries from the microphones if they will not be used for an extended period to prevent leakage.
- Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures.
- Antennas: Handle antennas carefully to avoid bending or breaking.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from microphones | Microphone off; low batteries; receiver off; incorrect cable connection; receiver not paired; audio device input incorrect. | Ensure microphones and receiver are powered on. Replace microphone batteries. Check all cable connections. Re-pair microphones with the receiver. Verify correct input selection on your audio mixer/amplifier. |
| Interference or static noise | Other wireless devices nearby; operating range exceeded; weak signal; frequency conflict. | Move closer to the receiver. Use the auto-scan function to find a clear frequency. Ensure antennas are properly positioned. Avoid placing the receiver near other electronic devices that may cause interference. |
| Microphone not pairing | IR windows not aligned; incorrect pairing procedure. | Ensure IR windows are facing each other closely during pairing. Follow the automatic or manual pairing steps carefully. |
| Short operating range | Obstructions; antenna position; environmental factors. | Ensure a clear line of sight between microphones and receiver. Position antennas vertically and away from metal objects. |
