Description: With TPA3116 LM1036, the power supply filter capacitor is 3300UF/25V. The main filter capacitor uses 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 red-grey ring is used for special power discharge to ensure the sound is crisp and powerful. Specification: Working method: Class D Bluetooth module: 4.0 Static current: 50 mA Work efficiency: 90% Rated output power: 2 * 50W Frequency response: 20Hz to 20KHz Operating voltage: DC18V to DC24V Maximum output current: 3A Size: Approx. 125x83x38mm Potentiometer function: treble, bass, volume (from left to right) Package Includes: 1 Piece Mini Bluetooth Amplifier 1 Piece Antenna
