Question answer:

1. How to choose a power supply?

The power supply of the board is critical.The higher the voltage, the larger the current, the more output the power. If you only have 12V 1A, you can bring a 3-4-inch speaker.If you are more than 19V 5A, with 8-10 inches, there is no problem, and the power supply must be highly valued.If the voltage is too low, the sound is easy to cause the sound distortion. If the current is too small, the horn will lower the voltage, the work is abnormal or the sound quality will deteriorate.

It is recommended to use the power supply of 18V19V24V, the current is above 5A.If you only have a power supply of 9V12V or 1A 2A, you can also use but the power is small. Pay attention to the maximum possibility of the volume when you use it and affect the sound quality.

2. How to choose a speaker?

The commonly used speakers are generally 4-8 ohms, which can not be distinguished from positive and negative poles. The effect is the same.If your speaker power is small, it may be used between 20W-50W. The power supply voltage is small to prevent burning the speaker after loud, such as selecting a power supply below 15V.If you are a 100W -200W speaker, you don't have to worry about the problem of the horn burn, you can choose the power of 12-24V. The higher the voltage you choose, the more output can be.The speaker power is not easy to exceed 200W, otherwise it will affect the sound quality.

3. Introduction to the audio input mode

There are two audio input methods for this audio amplifier module: one is Bluetooth input and the other is AUX input. The Bluetooth mode is preferred.No matter what mode, Bluetooth can be connected.As long as the Bluetooth connection is successful, it is the Bluetooth mode, and the Bluetooth mode supports automatic return.AUX insertion is the AUX mode when the Bluetooth is not connected.It should be noted that when using the AUX mode, you need to confirm that the Bluetooth connection of this module has been disconnected.

4. How to adjust the high bass?

The BASS potentiometer in the middle is controlled by the bass, the right rotation bass is enhanced, and the left -handed bass is attenuated.When the potentiometer is in the middle position, the bass is not enhanced or declining.

The Treble potentiometer on the left is controlled by the treble, the right rotation treble is enhanced, and the left rotating treble attenuation.When the potentiometer is in the middle position, the treble is not enhanced or declining.

When adjusting the high bass adjustment: When the treble or bass right rotation is close to the maximum, if the sound is distorted, it means that the gain of treble or bass adjustment is too great.The Volume volume potentiometer is left -handed on the right to reduce the total volume.

5. The sound is fine. After the sound becomes lighter, there is a turbid sound?

The sound is distorted, please change the power supply with higher voltage level.

6. The sound is fine. After the sound becomes lighter, the sound is stuck?

The power supply is insufficient, and the power supply is intermittently power -off. Please replace the power supply of a larger power; or the power is too large, the power amplifier board is severe, and the heat protection occurs. The power is reduced or the heat dissipation is reduced.

7. What are the factors of sound quality?

The quality of the sound quality is not only related to the amplifier module, but also has something to do with the sound source and the entire audio system.Basically, every link of the audio system will affect the sound quality. Among them, the main links are audio transmission lines, audio power supply, audio circuit, power amplifier circuit, speakers and surrounding environments.Only when the sound source, the amplifier module and the speaker are matched, the sound quality is the best.
