All parts and components of this product are original products, unpretentious and pure in quality; the use of high-quality original parts not only guarantees safety and quality, but also has a long service life, and more importantly, it is a strong guarantee that the actual performance can reach the design goals.
1. Using original TPA3116*2, ST 074C op amp
2. The power filter capacitor adopts 10pcs 470UF/35V electrolytic capacitors to ensure strong and continuous power support.
3. The coupling capacitor adopts the German Siemens fever-grade capacitor, and the human voice is more attractive.
4. 1% precision chip resistor is selected as the resistance to ensure a good signal-to-noise ratio of the whole machine.
5. 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.
6. The special power discharge sense of the red-grey ring is adopted to ensure the sound is clear and powerful.
7. With high-current luxury DC block, the current transmission is more stable.
