Description
NE5532 HIFI Tone Plate Audio Amplifier Board 50-150Hz Low Pass Crossover Amp Subwoofer 5.1 amplifier
Product Description
Use original NE5532. The main circuit of electrolytic capacitor signal adopts Taiwan famous brand, and the main filter capacitor adopts Japanese Ercon capacity 2×1000UF, and adopts 1A and above rectifier bridge to ensure strong and continuous power support. The resistance uses five-ring metal resistors, and the main circuit uses a five-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine. The left and right channel input coupling capacitors adopt Siemens 1UF coupling imported from Germany, the treble is clearer and the sound is sweeter! The high and low sounds are more perfect! PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tinning process to ensure good passing performance of large and small currents. First-class PCB quality. The fully enclosed dust-proof potentiometer has more stable performance and is more durable than ordinary potentiometers! Using gold-plated round hole IC socket, you can freely replace other op amp ICs according to your preferences The wiring layout of the whole circuit board is quite rigorous and reasonable, and the whole PCB wiring adopts a point grounding method. The work is stable and reliable, the low frequency is steady and powerful, the signal-to-noise ratio is excellent, and the dynamic range is wide; the details are clear, the transient response is excellent, and all kinds of music can be played freely, and it has a very good performance in the home environment.
