Instructions: 1 After receiving the product, please check whether the appearance is intact and whether the accessories are complete 2 Connect the power amplifier output to the speaker or speaker, R connects to the right channel, L connects to the left channel note the speaker pole Don t connect it backwards, the sound will be muddy if you connect it backwards) 3 Connect to the power supply the power supply can only be connected to direct current, the voltage should not exceed 25V, nor should it be connected to the standard Called 24V battery pack) 4 Turn the volume knob clockwise to turn it on, there will be a Bluetooth notification sound, and the blue light flashes at this time 5 Choose the audio input mode that suits you to input audio There are only three choices of audio input mode One, it cannot be started at the same time The audio input mode can be automatically recognized automatically recognized with priority, USB input>AUX input>Bluetooth input), or manually switched when multiple audio is connected at the same time, long press the pause/play button to switch the audio input mode 6 Rotate the volume knob, treble knob and bass knob to adjust the volume and treble and bass gain To the right place 7, quietly enjoy the happiness that music brings you common problem
Q: All the wires are connected, why the indicator light is not on?
Answer: Turn the volume switch to turn it on If it still does not light up after turning on, check whether the power supply is connected properly, and the power supply is positive There is no connection If everything is right, find a laptop power adapter power supply should not exceed DC25V or 12V battery power supply to determine whether it is a power supply problem or a product problem
Q: Why is the sound broken or distorted?
Answer: 1 The power supply voltage is too low, the volume is adjusted too much, the power supply is insufficient, and the sound will be distorted Suggest more Change to a high-voltage power supply or turn down the volume The power supply is sufficient, but the speaker power is too small, which will cause the speaker to overload and break the sound It is recommended to turn down the volume or replace with a higher-power speaker
Question: Why does the volume knob do not move, but connect to a different sound source such as first connect the CD and then change to the mobile phone sound The size is different?
Answer: If the volume knob is not moved, the sound magnification will not change And the audio signal amplitude output by different playback devices The value is different For example, the mobile phone is usually 0.35mV, and the CD is 1V, and the sound level is naturally different
Q: Why is there a loud current sound from the speaker?
Answer: The loud current sound in the speaker has a lot to do with the power supply The output pattern of many power adapters on the market If the wave is too large, it will interfere with the work of the power amplifier, and there will be a loud current noise Use a 12V battery to test it If the current sound is significantly smaller, it is a power supply problem It is recommended to replace the power adapter with low output ripple or use a battery for power supply
Question: Why does the audio output of the AUX audio input line be worse when one end of the AUX audio input line is connected to the product and the other end is not connected to the audio source? Big hum?
Answer: When the signal line without shielding is used, the audio line is equivalent t
