Feature:
The main circuit of electrolytic capacitor signal adopts famous brand, and the main filter capacitor adopts 470UF*14 to ensure strong and continuous power support.
The resistance uses five-ring metal resistors, and the main circuit uses five-ring metal film resistors with an accuracy of ±1% to ensure a good signal-to-noise ratio of the whole machine.
Left and right channel input coupling capacitors are coupled with E-LNA 2.2UF, the treble is clearer and the sound is sweeter! The combination of high and low sounds is more perfect!
The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and the whole process of spraying tin to ensure good passing performance of large and small currents. First-class PCB quality.
The fully enclosed dust-proof potentiometer is more stable and more durable than ordinary potentiometers!
The wiring layout of the entire circuit board is quite rigorous and reasonable. The work is stable and reliable, the low frequency is stable 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 it is easy to play all kinds of music. It has a very good performance in the home environment.
Front stage has a magnification switch, which can switch between 3.5 times and 7 times. The board is equipped with op amp socket, you can freely replace and upgrade the op amp according to your own hobbies, it is flexible and convenient to use, and meets different listening feelings.
