The original IRS2092 is adopted.
The main circuit of the electrolytic capacitor signal adopts a famous brand, and the main filter capacitor adopts a capacity of 4700UF/100V*2 to ensure a strong and continuous power support.
The resistance is made of five-ring metal resistor, and the main circuit is made of five-ring metal film resistor with accuracy of ±1% to ensure a good signal-to-noise ratio of the whole machine.
The PCB adopts 1.6mm thick double-sided plate, 2.0 Oz copper thickness, and the whole process of tin spraying to ensure the good passing performance of large and small currents. First-class PCB quality.
The 20A high current shielding inductor ensures the sound is crisp and strong.
This board comes with temperature protection circuit, the general power amplifier board is not there, the temperature reaches 75 degrees automatically disconnect the output, better protect the entire power amplifier board!
The entire circuit board wiring layout is quite rigorous and reasonable, and the overall PCB wiring uses 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 three-dimensional sense, low frequency calm solid and powerful, signal-to-noise ratio is quite excellent, wide dynamic range; The details are clear, the transient response is excellent, the playback of all kinds of music can be easily handled, and the performance is very good in the home playback environment.
