Amplification Function: It can effectively amplify the power, give the machine greater impedance, make the machine have a higher level of performance, and bring you an extremely good sense of use. Scope of Application: The power supply voltage is DC 7V-15V, it is recommended to use 12V, 3A power filter. It uses a digital chip, and its efficiency can reach more than 90%, so it has the advantages of high power and low heat. Made of high-quality materials, stable and durable, when the audio input is sufficient and the power supply voltage/current is sufficient, sufficient output power is required, and the relative power will be higher.
