LM3886+5532 Combined Power Amplifier Board 68W*2 DIY Assembly Power Amplifier Board HIFI Audio Amplifier Board
Product Description:
All parts of this product are original, unpretentious and pure in quality; the use of high-quality original parts is not only a guarantee of safety and quality, long service life, but also a strong guarantee that the actual performance can reach the design goal. The pursuit of first-class quality is our consistent aim.
product details:
NE5532 audio-specific op amp IC, this IC has a warm tone and a balanced atmosphere, and is often used as a preamplifier; LM3886 is a well-known high-performance audio power amplifier integrated circuit from National Semiconductor (NS), with a maximum output power of up to 68W. Accurate and vivid, noise and distortion are quite low, and the protection function is relatively complete, stable performance. Once the LM3886 was launched with rave reviews, it quickly became the configuration of the large and medium power HIFI audio amplifiers and high-fidelity active monitor speaker amplifier circuits. These two IC audio enthusiasts can be said to be well-known and well-known; despite the rapid development of audio technology over the years, these two ICs are still widely used and enduring due to their outstanding performance and sound quality. The famous American audio manufacturer Lelin has an expensive and famous machine with LM3886 as the amplification core. It can be said that LM3886 is one of the audio power amplifier ICs that every audiophile must play and often play.
The power of this power amplifier board is a 2¡¿68W dual-channel front and rear stage combined power amplifier board.
Using original LM3886 and JRC5532.
The pre-input capacitor and inter-stage coupling capacitor use WIMA top-level capacitor 1.5UF, the main circuit of electrolytic capacitor signal adopts Taiwan famous brand, the main filter capacitor adopts NOVER capacity of 2¡¿10000UF, and the domestic rectifier flat bridge of 8A and above is used to ensure a steady stream of strong power. Power support.
The five-ring metal resistor is used for the resistor, and the five-ring metal film resistor with an accuracy of ¡¾1% is used for the main circuit, which ensures a good signal-to-noise ratio of the whole machine.
The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. Top-notch PCB quality.
The special design of this board is the use of jumpers between the front and rear stages, so that the volume potentiometer can be placed before the pre-input or after the pre-amplifier, so that the noise and distortion are smaller and the dynamics are better.
The wiring layout of the entire circuit board is quite rigorous and reasonable, and the overall PCB wiring adopts a one-point grounding method. The power amplifier board works stably and reliably, with large output power; the sound is beautiful and round, and the sound field is wide. Strong stereo sense, stable and powerful low frequency, excellent signal-to-noise ratio, wide dynamic range; clear details, excellent transient response, can handle all kinds of music with ease, and has a very good performance in home playback environment.
The wiring of this board is very simple, and it can be assembled into a stereo HIFI integrated power amplifier with beautiful sound with only a few components, which is very suitable for audio enthusiasts to make and use. You can also replace with more suitable and better parts according to your own understanding of the circuit, and enjoy the fun of the DIY process. (Definitely worth a try, works really well)
Basic parameters:
PCB board size: 117*95mm
Note that this is a semi-finished product, as shown, without a heatsink.
