[Details]2013 The latest three-channel LM3886 2.1 subwoofer amplifier board about using the coupling method channels and classic Wu Gang circuit
All components of this product are original authentic, pure unpretentious, quality; the use of high-quality original parts, not only quality and safety are guaranteed, long service life, more importantly, that the actual performance can meet the design goal of a strong guarantee. Pursuit of the best quality is the consistent aim of our restaurant.
n New original LM3886 and NE5532.
n Front input capacitance and inter-stage coupling capacitor uses advanced WIMA capacitors 1.8UF, electrolytic capacitor signal of the main circuit using the advanced Nikon 4700UX6, Rectifier 25A and above the use of flat bridge, ensure strong support for a steady stream of power.
n Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio.
n PCB 1.6mm thick sheet using double-sided, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. PCB-class quality.
n Negative feedback tuning pre-tuning of the design, can reduce crossover distortion, a better sense of hearing.
n Selection gilt hole IC Block, not a general IC Block, more durable
The entire circuit board trace layout are very strict and reasonable, the overall PCB traces using a little grounding. The amplifier board is stable and reliable, high output power; beautiful mellow sound, open sound field. Dimensional sense of strong, low-frequency steady solid and strong, very good signal to noise ratio, wide dynamic range; details clear, excellent transient response, play a variety of music all rise to the occasion, at home playback environment has a very good performance.
