Setup Guide
- Unpack and Inspect: Carefully remove all components from the packaging. Inspect for any signs of damage. Refer to the "Package Contents" section to ensure all items are present.
- Receiver Placement: Place the wireless receiver on a stable, flat surface. Ensure there is adequate ventilation around the unit. The built-in antennas are fixed and do not require assembly.
- Power Connection: Connect the provided power adapter to the DC IN jack on the back of the receiver and plug it into a suitable power outlet.
- Microphone Battery Installation: Unscrew the bottom cap of each handheld microphone. Insert two AA batteries into each microphone, observing the correct polarity (+/-). Replace the bottom cap securely.
- Audio Output Connection:
- For individual microphone outputs, connect XLR cables (not included) from the Balanced XLR Output ports on the receiver to your audio mixer or PA system.
- For a mixed output, use the provided 1/4" audio cable from the 1/4" Audio Output Jack on the receiver to your amplifier, speaker, or karaoke machine. Use the 6.35mm to 3.5mm adapter if connecting to a 3.5mm input.
- Power On: Press the power button on the receiver to turn it on. The LCD display will illuminate. Turn on each handheld microphone by pressing and holding its power button. The microphone display will show its channel and battery status.
- Frequency Synchronization: The system is designed for automatic synchronization. If a microphone is not connecting, ensure it is within range and its frequency group matches one of the receiver's channels. Refer to the "Operating" section for changing frequencies if needed.

Operating Instructions
Microphone Operation
- Power On/Off: Long press the power button on the microphone for 3 seconds to turn it on or off.
- Mute Function: Short press the power button (1 second) to mute the microphone. The display will flash while muted. Short press again to unmute.
- Frequency Switching: Each microphone has a "SET" button. Short press this button to cycle through available frequencies within its assigned group. The display will show the new frequency number. Note: To sync a new frequency with the receiver, you may need to power cycle the receiver after changing the microphone's frequency.
- Battery Indicator: The microphone's display shows a real-time battery indicator. Replace batteries when the indicator shows low power to ensure uninterrupted performance.

Receiver Operation
- Volume Control: Adjust the individual volume knobs on the receiver for each channel (CH A to CH H) to control the output level of each microphone.
- LCD Display: The receiver's LCD display shows the active channel assignments and signal status for each microphone.
- RF Signal Indicator: Observe the RF signal indicators on the receiver to ensure a strong wireless connection for each channel.
- AF Audio Signal Indicator: The AF audio signal indicators light up when audio is being received from the corresponding microphone.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the receiver and microphones. Do not use abrasive cleaners or solvents.
- Battery Replacement: Always replace all AA batteries in a microphone simultaneously with new ones. Do not mix old and new batteries or different battery types. Remove batteries if the microphones 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.
- Handling: Handle microphones with care. While designed to be durable, excessive drops or impacts can cause damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from microphone. | Microphone off, muted, low battery, out of range, incorrect frequency, receiver off, audio cable disconnected. | Ensure microphone and receiver are powered on. Check microphone battery level and replace if low. Verify microphone is not muted. Ensure microphone is within 240ft range. Confirm microphone frequency matches receiver channel. Check audio cable connections to mixer/speaker. |
| Interference or static noise. | Other wireless devices, strong electromagnetic fields, multiple systems on same frequency, too far from receiver. | Change the microphone's frequency using the SET button. Ensure no other wireless devices are operating on the same frequency. Reduce distance between microphone and receiver. Avoid placing receiver near strong electrical interference sources. |
| Microphone display is dim or off. | Low battery. | Replace both AA batteries in the microphone. |
| Difficulty changing frequencies. | Incorrect procedure. | Ensure you are short-pressing the "SET" button on the microphone. If the receiver needs to sync, power cycle the receiver after changing the microphone's frequency. |
| Plosives or sibilance in audio. | Microphone technique, lack of pop filter. | Maintain proper distance from the microphone. Consider using an external pop filter or windscreen. Adjust EQ settings on your mixer if available. |
