The DX AMP circuit is compact and simple, requires fewer components, has transparent sound, and powerful bass, making it easy to create a amplifier with good sound quality It's worth a try. . ● There are clear component markings on the PCB, and no schematic diagram is provided. ● Before powering on, the heat sink needs to be properly treated, and insulation treatment should be done between the transistor and the heat sink. ● Static current regulation method: Install the heat sink on the finished board, connect the positive pole of the DC ammeter in series, adjust the 202 adjustable resistor on the board to make the static current around 10-100mA,. ● Mid point voltage adjustment: Short circuit the input terminals IN and GND, and adjust the 10K (103) adjustable resistor on the board to make the output (OUT) to ground (GND) terminals close to 0mV. Clockwise adjustment decreases, counterclockwise adjustment increases. Parameters:
● Output power: 100W ● Frequency response: 20Hz-20KHz ● Signal to noise ratio: 92db ● Working voltage: DC dual 30-45V (8 Ω) three wires DC dual 30-35V (4 Ω) three wires ● Size: 90 * 49.5 * 45mm List:
1 x DX AMP Circuit amplifier board This amplifier board is designed for mono sound. If you need stereo sound, please purchase even numbers.
