Finished DA7498 TL072 2.1 Digital Class D Amplifier AMP Board 200W+100W+100W

Description

DA7498 TL072 2.1 Digital Class D Amplifier AMP Board 200W+100W+100W
Product desciption:
1.Using original TDA7498 TL072
2.The front input capacitor and the inter-stage coupling capacitor use Siemens top-level capacitor 1UF, the electrolytic capacitor signal main circuit uses Taiwan famous brand, and the main filter capacitor uses Japanese Panasonic special electrolytic capacitor capacity 2×2200UF to ensure a strong source of continuous power support.
3.The resistor uses high-precision chip resistors, and the main loop uses a five-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio for the whole machine.
4.PCB adopts 1.6mm thick double-sided board, 2.0 ounce copper thickness, full tin spraying process to ensure good passing performance of large and small currents. First-class PCB quality.
5.Using fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometer.
6.Adopt red-ring high-current inductance to ensure crisp and powerful sound.
