Product Details:
The board adopts an integrated design, on-board rectification and filtering, and on-board 1237 protection circuit.
The wiring is simple and there is no need to worry about interference.
This board is a UPC1342V push high-power tube structure, the quiescent current of the final high-power tube is adjustable, and it can output Class A sound.
This circuit adopts a dual-channel design with clear layout, and the power supply and protection circuit are far away from the amplifying circuit
Output power: According to the different power supply voltage and speaker impedance, the output power is 20~150W; when AC35V power supply, it can output 100W*2/8 ohm, 150W*2/4 ohm.
Midpoint voltage: about 1mV;
Signal to noise ratio: 105dB
Noise level: 0.4mV
Power supply range: AC18X2~AC36X2
PCB size: 88*150MM
