Description <br> Description: <br> Subwoofer Digital Power Amplifier Board <br> The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current and the first-class PCB quality. <br> With a fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers. <br> Small size, high power, no noise, the circuit design is very reasonable, without any low noise! <br> Electrolytic capacitors use imported 2200UF/35V electrolysis to ensure a strong and continuous power support. <br> The resistor uses 1206 0805 high-precision chip resistor to ensure a good signal-to-noise ratio of the whole machine. <br> <br> Specification: <br> Working method: Class D <br> Work efficiency: 90% <br> Rated output power: 150W*1 <br> Working voltage: DC18V to DC32V <br> Power supply voltage: DC32V <br> Maximum output current: 6A <br> Quiescent current: 20mA <br> Speaker impedance: 4-8 ohms <br> Package Includes: <br> 1 Piece Stereo Audio Amplifier Board <br> <br> Note: <br> Please allow 0.5-1 inch difference due to manual measurement.(1 inch=2.54cm) <br> Due to the difference between different monitors, the picture may not reflect the actual color of the item. Please understand, Thank you. <br>
