All the component are original certified goods, Chastity, pure quality; use the high quality original components, not only guarantee the safe and quality, extend the service life, the more important is strongly guarantee to actual performance can meet the design target. The pursuit of first-class quality is our consistent aim.
Adopted original IRS2092, IRFB23N15D.
The main circuit of electrolytic capacitor signal uses ELNA, NXB brand, main filter capacitor uses Japanese chemical capacity 4700UF/80V*4, adopting 25*2 (50A) rectifier flat bridge, to ensure the supporting power.
The selection of resistance is five metal resistance, the main circuit adopts the metal film resistor which accuracy is ±1%, guarantee the signal-to-notice ratio of the product.
PCB adopts 1.6mm thickness double-sided board, 2oz copper thickness, spray tin full process, ensure the current well done through the performance, first-class PCB quality.
Adopted 20A big current shielding inductance, ensure sound crisp and powerful.
Add UPC1237 speaker protection circuit that is advanced, 30A relay control, effectively control the boot impact sound, make your horn safer.
The circuit board wiring layout is quite rigorous and reasonable, the whole PCB lines with one point grounding mode. The power amplifier board is stable and reliable working, high output power; beautiful voice, the sound open field. Strong stereoscopic sense, low frequency sounds deeply and stable, the signal-to-noise ratio is quite well, widely dynamic range, excellent transient response; clear details, all kinds of music can be handled a situation with ease, has a good performance in the family environment.
The use of voltage range: double 20V-50V (AC rectified voltage of ± 28V-70V), pay attention to voltage in the AC 35V, R6 R7 (4.7K 3W) to 2K Ω /3W resistance. (shipping default voltage of 40-45V, R6 R7 3.9K)
