4 x 150W LM3886 X 3 channel Audio Amplifier Board

Product details

Using original LM3886.Top-level input capacitance capacitors 4.7UF, electrolytic capacitors using ELNA brand signals the main loopResistance selection chip resistors to ensure a good signal to noise ratio of the machine.Double-sided PCB with 1.6mm thick plate, 2.0-ounce copper thickness, HASL entire process to ensure the size of the current through the performance of the good. PCB-class quality.The alignment of the entire circuit board layout are very strict and reasonable, the overall PCB trace with little grounding. The amplifier board stable and reliable output power; sounds beautiful and smooth, open sound field. Three-dimensional sense of strong, steady low-frequency sound, very good signal to noise ratio, dynamic range is wide; to detail, excellent transient response, playing a variety of music, both are comfortable with, the playback in the home environment, there is a very good performance.

the panel wiring is very simple, as long as the minimal configuration can be assembled into components a beautiful stereo sound combined type HIFI power amplifier, ideal for audio enthusiasts making use of.

amplifier is used fiber glass PCB,.Excellent electrolytic capacitorsfilm capacitors and precision metal film resistors. it hasn't DC power supply on board .so you need PUS Fiter kit and connect the power transformer and aluminum heatsink to run it.
