Why isn't the wireless PA system powering on?
Check the Power Switch: Locate the ON/OFF power switch on the PA system and ensure that it is switched to the "ON" position.

Check the Power Connection: Make sure the PA system is properly connected to a power source and that the battery is charging. If the battery is depleted, connect the system to the power adapter and allow it to charge.
Why is there no sound output from the wireless PA system?
Check the Master Volume: Ensure that the master volume is adjusted to an appropriate level. If it is too low or muted, there will be no sound output.

Check Individual Audio Sources: Verify that all connected audio sources (e.g., microphones, music players) are powered on and that their individual volume levels are also adjusted to the appropriate level.
Why is the PA system's sound quality abnormal?
Check EQ Settings: Ensure that the EQ (Equalizer) settings for high, mid, and low frequencies are not drastically different from each other. Extreme EQ settings can cause sound distortion.

Verify Impedance Connections: Make sure that the impedance between the input and output connections is correctly matched. Incorrect impedance settings can lead to poor sound quality.

Check Voice Priority Function: Verify if the voice priority function is activated, which may affect sound quality by prioritizing certain audio inputs over others.
How can I eliminate feedback noise in a wireless PA system?
Adjust and Lower Volume: Reduce the overall volume or decrease the microphone's sensitivity to minimize feedback.

Microphone Positioning: Avoid standing directly in front of the speaker while holding the microphone. Ensure the microphone is at least 3 meters away from the speaker and not pointed directly at it.

Proper Speaker Placement: Position the wireless PA system between the speaker (person talking) and the audience, directing the speaker output towards the audience.

Use a Tripod: Mount the wireless PA system on a dedicated tripod, ideally at a height above the average person's head (approximately 180 cm), to reduce the chances of feedback.
Why is my wireless PA system experiencing short reception distances or signal dropouts?
Maintain Clear Line of Sight: Ensure that the transmitter and the wireless PA system maintain a clear line of sight without obstacles for optimal reception.

Elevate the PA System: Mount the wireless PA system on a tripod or place it on an elevated surface above the ground level. Keep it away from metal objects, metal surfaces, computers, digital and electronic devices, and lighting systems to avoid external interference and improve reception quality.

Check for External Interference: If the receiver module's signal indicator light is still on even when the transmitter is off, it indicates external interference. Reducing the sensitivity of the receiver module can help avoid interference, though it may shorten the reception distance.

Adjust Receiver Sensitivity: To extend the reception distance, you can increase the sensitivity of the receiver module, but this may also increase the chances of external interference.

Use TURE Diversity Receiver Module: Choosing a TRUE diversity receiver module can improve microphone signal dropouts.

Use the SCAN Function: Utilize the receiver module's SCAN function to find a clean frequency, which can help restore the reception distance.
Power indicator is not on.
Use an external AC power source to check if the indicatort turns on.

If the power indicatort turns on, it indicates the battery is dead. Please charge it and try again.
MP3 Player has no sound.
Check if the power is turned on.

Ensure the volume knob on the player is adjusted to an appropriate level.

Check if the LCD display indicates reading and playback.
