TPA3116 2.1+ AK4490 Bluetooth 4.0 Digital Amplifier (Including DC24V switching power supply)   product details All the parts of this product are genuine and authentic, simple and pure, and the quality is pure; using high-quality original parts not only guarantees the safety and quality, long service life, but also the strong guarantee that the actual performance can meet the design goals. The pursuit of quality is our consistent aim.   ①Using the original TPA3116 and CSR4.0 Bluetooth module ②Coupling capacitor adopts German Siemens 1UF ③ The main circuit of the electrolytic capacitor signal adopts the Taiwan famous brand, and the main filter capacitor adopts the Japanese ELNA electrolytic capacitor to ensure a strong continuous power support. ④ The resistor is 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 for the whole machine. ⑤ The PCB uses 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of spraying tin to ensure the good passing performance of large and small currents. Best-in-class PCB quality. ⑥ Fully enclosed dustproof potentiometer, more stable performance and more durable than ordinary potentiometers! ⑦Using red and gray ring audio special high current inductor to ensure crisp and powerful sound. ⑧The machine uses an all-aluminum chassis, and the surface of the chassis is all treated with a brushed oxidation coloring process! ⑨Using the latest Bluetooth version 4.0 ⑩External gold-plated Bluetooth antenna, better receiving ability, receiving range 10 meters ⑪ The connection method of Bluetooth is the same as that of ordinary devices! ⑫The input methods include Bluetooth and analog input. When both methods are used at the same time, Bluetooth input is preferred. Please turn off the Bluetooth function of the mobile phone when analog input is needed. ⑬Appearance size: knob to antenna 220 * width 130 * height 45MM (excluding antenna) antenna height 11CM     Basic performance parameters: ①Working method: Class D ② Static current: 50mA ③Working efficiency: 90% ④ Rated output power: 100W + 2 * 50W ⑤ Frequency response: 20Hz to 20KHz ⑥Working voltage: DC18V to DC24V ⑦Max output current: 3A ​
