Description: The resistor uses a five-ring metal resistor, and the main loop uses a five-ring metal film resistor with an accuracy of ±1% to ensure a good signal-to-noise ratio. The PCB uses a 1.6 mm thick double-sided board, 2.0 oz copper thickness, and a full tin spray process to ensure good current-through performance, first-class PCB quality. Red-gray ring dedicated power discharge sense to ensure that the voice is crisp and powerful,Simple compact design but practical and powerful. Some customers complaint the power supply, we had changed it, the new one is 90 watts that can be carefully matched with this integrated amp physically as well as electrically. 50W X 2 (4 ohms, 20 Hz - 20 kHz, 0.04% THD), can power most home speakers, advanced circuitry design, built-in speakers protection circuit, solid aluminum chassis for long time use. Specification: 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. 90x140x40mm / 3.54x5.51x1.57inch Package Includes: 1 Piece Mini Amplifier
