Adopt original NE5532.
Electrolytic capacitors signaling the main circuit using Taiwan, the main filter capacitor using Japan Erkang capacity 2 × 1000UF, using 1A and above rectifier bridge, to ensure a strong source of constant power support.
Resistor selection of five-ring metal resistors, the main circuit using precision ± 1% of the five-ring metal film resistors, to ensure a good signal-to-noise ratio of the whole machine.
Left and right channel input coupling capacitors imported from Germany Siemens 1UF coupling, treble more clear sound more sweet! Bass and treble are more suitable!
PCB using 1.6mm thick double-sided plate, 2.0 ounces of copper thickness, spray tin full process, to ensure that the size of the current through a good performance. The PCB quality.
Adopt fully enclosed dustproof potentiometer, more stable performance, more durable than ordinary potentiometer!
Adopt gold-plated round hole IC seat, you can freely replace other op-amp ICs according to your preference.
The layout of the entire circuit board alignment is quite rigorous and reasonable, the overall PCB alignment using a point of grounding. Stable and reliable work, low-frequency stability and solid power, signal-to-noise ratio is quite excellent, wide dynamic range; clear details, excellent transient response, play a variety of music are coping with, in the family's sound environment has a very good performance.
