NONDK 1000Wx2 2-Channel Power Amplifier Board High-Power Amplifier Board DIY HIFI Professional Stage Amplifier Audio with Circuit Protection

The circuit design uses DC feedback, good analysis, dive is sufficient, high-power work excellent. Recommended the use of AC dual 35-70V toroidal transformer (400w or more), and then add rectifier power supply board after use, the protection circuit requires a separate power supply (AC 12-18v, must use windings, can not be shared with other), 400w transformer is just a reference, in fact, can reach high power output transformer also need to be larger. The amplifier board also comes with a complete protection circuit, power on/off delay protection, midpoint voltage protection, overcurrent protection, high temperature protection, and cooling fan interface. Product Description: This amplifier board from a and stable circuit, dual differential input and increased signal processing at the input, drive stage with a pair of transistors 1930 5171 plus 5200 1943 for composite drive, and then 22 transistors for the power stage output, the maximum power output can reach 1000w +1000w, power is very strong, the low frequency is very strong, rich in detail. Before shipping the amplifier board has been all tested and debugged.
