The power supply with the board is critical. The higher the voltage, the greater the current, and the greater the output power That’s enough, if you only have 12V 1A, you can bring 3-4 inch speakers. If you are 19V Above 5A, with 8-10 inches No problem, the power supply must be paid attention to. If the voltage is too Amplification of low sound will easily cause sound distortion, if the current is too small, The speaker will pull down the voltage, work abnormally or the sound quality will deteriorate. It is recommended to use a power supply of 18V19V24V with a current above 3A. If you only have 9V12V Or 1A 2A power supply, can also be used but the power is low, pay attention to the volume when using The maximum possible distortion will affect the sound quality. 2. How to choose a speaker? Commonly used speakers are generally 8 ohms, you can not distinguish between positive and negative polarity, the effect is Similarly, 4 ohm speakers can also be used. If your speaker has low power, It may be available between 10W-30W, The supply voltage is smaller to prevent Burn the speaker after loud, for example, choose a power supply below 15V. If you are 50W-100w Speaker, don’t worry about the speaker burnout, you can choose 12-24V Source, the higher the selected voltage, the greater the output sound or power. La 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 hardware first principle. USB connection is successful Type, AUX insertion is AUX mode. If USB is not connected and AUX is not Plug it in, it is in Bluetooth mode, which supports automatic connection back. When switching modes There is a pattern tone. When selecting the USB audio input mode, note that the USB To directly connect to a computer and other devices with USB audio output, no driver is required.
