Question answer:
1. How to choose a power supply?
The power supply of the board is very important. The higher the voltage, the greater the current, and the more sufficient output power. If you only have 12V 1A, you can bring 3-4 inch speakers. If you are above 19V 5A, there is no problem with 8-10 inches, and the power supply must be highly regarded. If the voltage is too low, the amplified sound will easily cause sound distortion. If the current is too small, the speaker will pull down the voltage, which will result in abnormal operation or poor sound quality.
It is recommended to use a power supply of 18V19V24V with a current of 3A or more. If you only have 9V12V or 1A 2A power supply, you can also use it but the power is low. Note that when the volume is maximized, it may be distorted and affect the sound quality.
2. How to choose a speaker?
Commonly used speakers are generally 8 ohms, and the positive and negative polarities are not distinguished, and the effect is the same. 4 ohm speakers can also be used. If your speaker has a low power, it may be between 10W-30W. The power supply voltage is lower to prevent the speaker from burning after the amplified sound. For example, choose a power supply below 15V. If you have a 50W-100w speaker, don't worry about the problem of speaker burnout. You can choose a 12-24V power supply. The higher the voltage you choose, the greater the sound or power that can be output. The speaker power is not easy to exceed 100W, otherwise it will affect the sound quality.
3. How to choose audio input mode?
This audio power amplifier module follows the principle of hardware first. A successful USB connection is in USB mode, and AUX insertion is in AUX mode. If the USB is not connected and the AUX is not plugged in, it is in Bluetooth mode, and the Bluetooth mode supports automatic connection back. There will be a mode prompt sound when the mode is switched. When selecting the USB audio input mode, it should be noted that the USB can be directly connected to a computer and other devices with USB audio output without installing a driver. The USB input is a lossless input, with good sound quality, no interference, and no noise.
4. It's okay if the voice is small, but when the voice becomes louder, the voice becomes muddy?
The sound is distorted, please change to a higher voltage adapter power supply.
5. It's okay if the voice is small, but when the voice becomes louder, the voice freezes?
The input power is insufficient, and the power supply itself is protected against intermittent power failure. Please replace it with a higher-power power supply; or if the power is too large, the power amplifier board generates serious heat and thermal protection occurs. Reduce power usage or enhance heat dissipation.
