Homemade 100WX2 Hi-Fi Power Amplifier ----- 100W Hi-Fi Power Amplifier

Homemade 100WX2 HI-Fi power amplifier, 100W HI-FI power amplifier Keyword: HI-FI amplifier, 100W power amplifier circuit, STK2100 amplifier circuit Many people like to use fever Sanyo STK Series power amplifier circuit, such as STK4131. STK4191, etc., but the drawback is that these power amplifier using transistor output, its frequency response, distortion and dynamic range of leisure and other indicators are high. Here, the reader introduces an excellent high-fidelity active audio mixing integrated circuit STK2100 IISTK2100 II is a high-powered high power amplifier integrated circuit. Using the output of the power FET having a characteristic tube. Output power 100WX2, frequency response is 10Hz ~ 20kHz, circuit minimum voltage of ± 12V, the maximum is ± 50V, distortion of 0.001%. Use it to produce high-quality amplifier that external circuit is very simple, distortion, frequency bands and output power and other parameters have reached a good indicator. Circuit shown in FIG. 5-84, VD3 speaker pickup bridge circuit, when the amplifier circuit is normal, R, L and only the AC signal, no DC voltage pick-up circuit does not work, VTI off, VT2, VT3 conduction, K pull. ON speaker amplifier output. When the circuit failure, conduction VT1, VT2, VT3 end, K release, speaker plants obtained effectively protected. IC1 fever stage low noise operation, high slew rate amplifier NE5535, NE5535 output circuit is a PNP-NPN complementary fully symmetrical structure, there is a certain quiescent current biasing, the circuit is very simple. It has an open loop frequency response, high unity gain bandwidth. High conversion rate, small open-loop distortion, noise and instantaneous characteristics, etc., use it to do Hi-Fi audio pre-circuits into an ideal chip, and is known as the emperor of the op amp. This circuit 250W power transformer ring selected "adapters", pre-amplifier and power supply separate, high capacity coupled with high quality electrolytic capacitors, and therefore has sufficient reserve power. All are high-resistance metal film resistors in the circuit. Tantalum capacitor and CBB capacitor. Therefore the whole person micro-capsules treble, midrange and bright thorough, strong and deep bass, with the "guts" wind machine
