LM3886 NE5532 High-performance Audio Power Amplifier Circuit Board DIY Stereo HIFI Combined Amp LM3886 Amplifier Board
Product Description
LM3886 is a prestigious high-performance audio power amplifier integrated circuit of NS in the United States. The maximum output power can reach 68W, the sound is accurate and vivid, the noise and distortion are quite low, and the protection function is relatively complete and the performance is stable. Once the LM3886 was launched with rave reviews, it quickly became the configuration of high and medium power HIFI audio amplifiers and high-fidelity active monitor speaker amplifier circuits. This IC audio enthusiast can be described as no one knows, no one knows. Despite the rapid development of audio technology over the years, these two ICs are still widely used due to their outstanding performance and sound quality. They are still enduring. Lelin, a well-known American audio manufacturer, has an expensive machine with LM3886 as the core of amplification. It can be said that LM3886 is one of the audio amplifier ICs that every audio enthusiast must play and often play.

Feature
1. Adopt original laser dark characters LM3886TF, NE5532. 2. The resistance adopts five-ring metal resistance, and the main loop adopts five-ring metal film resistance with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine. 3. The main filter electrolytic capacitor adopts the famous brand of NOVER audio special capacitors with a capacity of 10000UF/50V*2, which guarantees a strong and continuous power support. 4. The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin-spraying process to ensure good passing performance of large and small currents. First-class PCB quality 5. In particular, the current advanced UPC1237 speaker protection circuit is added to effectively control the start-up impact sound and make your speakers safer. 6. The wiring layout of the whole circuit board is quite rigorous and reasonable, and the overall PCB wiring adopts one-point grounding. The power amplifier board is stable and reliable, and the output power is large; the sound is beautiful and round, and the sound field is wide. Strong three-dimensional sense, low frequency is stable and powerful, the signal-to-noise ratio is quite excellent, the dynamic range is wide; the details are clear, the transient response is excellent, and all kinds of music can be played with ease, and it has a very good performance in the family's playback environment. 7. The wiring of this board is very simple. As long as there are few components, it can be assembled into a beautiful stereo HIFI combined power amplifier, which is very suitable for audio enthusiasts. You can also replace the more suitable and better parts according to your understanding of the circuit, and enjoy the fun of the DIY process. (Absolutely worth a try, the effect is very good)
