Notes for use: The power switch on the board is standby switch, and the machine is in standby state with low power consumption after the switch is turned off. To completely turn off the power or to remove the DC plug on the machine for a long time, it is ok. Question answers: 1. How to choose the power source? The board’s power supply is crucial.The higher the voltage, the greater the current, the more power output, if you only have 12V/1A, this can carry 3-4 inch speakers.If you are above 19V/5A, 8-10 inches is fine.Power supply must be highly valued.If the voltage is too low, the sound will easily cause distortion after amplification. If the current is too low to carry the speaker, the voltage will be pulled down, and the work will be abnormal or the sound quality will be poor. It is recommended to use 18V19V24V power supply with current above 5A.If you only have 9V12V or 1A 2A power supply, you can also use it with low power. Be careful when using it at the maximum volume, it may cause distortion and affect the sound quality. 2. How to choose the speaker? Common speakers are usually 8 ohms, can not distinguish between positive and negative polarity, the effect is the same, 4 ohms can also be used.If your horn power is small, it may be between 10W and 30W can also be used. The power supply voltage is small to prevent the speaker from burning down after playing loudly. For example, choose the power supply below 15V.If you are a 50w-300w speaker, don’t worry about the speaker burning problem, you can choose a 12-24v power supply, the higher the selected voltage, then the greater the output sound or power. 3. How to choose bluetooth or AUX audio input mode? Power up the power amplifier board, connect to the speaker, rotate the audio knob and the blue indicator light turns on, turn on the phone Settings — bluetooth — search to “bt-wuzhi”, and then click connect, after connecting successfully, there will be ding dong prompt sound, at this time for bluetooth mode, play music can, next time on the power will automatically connect back with the phone. If you want to use AUX audio input, then disconnect the bluetooth connection, there will be an audio prompt, insert the audio cable to play music.IN AUX (LINE IN) mode, the connection bluetooth automatically converts to bluetooth mode. 4. The sound is small, and when the sound becomes louder, why does the sound appear turbid? The sound has been distorted. Please replace the adapter with a higher voltage level. 5. The sound is small and the sound is getting louder. Why does the sound appear to be stuck? The power of the input power is insufficient, and the power supply itself is intermittent power failure protection, please replace the power supply with higher power;Or if the power is too large, the power amplifier plate generates serious heat, and the situation of thermal protection occurs. Reduce the power to use or check whether the heat sink fits well to strengthen the heat dissipation. Note: The case needs to be assembled by yourself. Free screwdriver.
