Product Introduction

The amplifier board welding good product, directly connected to the power supply, audio, speakers can work. This product uses two digital amplifier TPA3116D2 chip as the core, make a left and right channel power amplifier, a subwoofer bridged drive, small size, high efficiency, high power characteristics. Regardless of the cost of materials, capacitance WIMA, Siemens, Nikon fever capacitance. Taiwan producing high-quality sealed miniature potentiometer, original TPA3116 chip, dedicated bass sound chip. Board circuit is simple, reliable work. Operating voltage single supply 12V-26V. Left and right channel output maximum 50WX2, subwoofer output maximum 100W, efficiency can reach more than 90%, you can use switching power supply of notebook computers, it is also very suitable for battery-powered equipment, such as motorcycles, cars, electric cars and so on. Compact board, use and installation are very flexible and convenient. All components used to use genuine devices, capable of long-term stability.
