The power supply filter capacitor uses an imported capacitor of 1800UF\/25V and a coupling capacitor of 1UF. The first-class electrolytic capacitor signal main circuit, the main filter capacitor uses imported electrolytic capacitors to ensure a strong source of continuous power support. The resistor uses a five-ring metal resistor, and the main circuit uses a five-ring metal film resistor with an accuracy of  ±1% to ensure a good signal-to-noise ratio. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current. The use of fully enclosed dust-proof potentiometers, the performance is more stable and durable; the use of fully shielded audio dedicated high-current inductors to ensure that the sound is crisp and powerful. Specification: Working method: Class D Quiescent current: 60mA Work efficiency: 90% Rated output power: 100W+2*50W Frequency response: 20Hz to 20KHz Working voltage: DC18V to DC24V (internal + external - 5.5*2.1) Maximum output current: 3A Package Includes: 1 Piece Bluetooth TPA3116 Stereo Amp Board SKU: FUZ0027391363021224.Adopts TPA3116 and Bluetooth 4.2 modules. 1 Piece Bluetooth TPA3116 Stereo Amp Board.
