2 CH Home Audio HIFI 300W Amplifier Board 150W * 2 Dual Channel UPC1342V 2SC5200 2SA1943 Amplifier Board

PCB Size: 150X88MM
Power supply range: AC18X2 – AC36X2 .
Core circuit:The excellent performance of broadband low distortion 50w drive circuit UPC1225H, in order to meet the requirements of high power has introduced a new generation of audio driver IC – UPC1342V, the IC in addition to all the advantages of UPC1225H and basically the same external circuit , The output voltage deviation is smaller (± 5mV), the voltage to adapt to a wider range (± 20 ~ ± 70V), to promote the power more abundant, called the Friends of the preferred amplifier amplifierIC.Circuit design: The board uses one design, onboard rectifier filter, onboard 1237 protection circuit. Wiring is simple, do not worry about interference problems. This circuit is UPC1342V push high-power tube structure, the line is simple, the last high-power tube quiescent current adjustable, can output a class of sound; the circuit with two-channel design, clear layout,power and protection circuit and amplifier circuit distance far
Output power: According to the different power supply voltage, speaker impedance of the different output power 20-150w; when AC35v
power supply, the output 100w * 2/8 ohm, 150w * 2/4 ohm.
Midpoint voltage: 1mV or so;
Signal to noise ratio: 105dB, noise level: 0.4mV
