2x150W no large loop feedback hi-fi amplifier


Posted on Mar 28, 2007

As we all know, from the amplifier output stage to the previous stage, although a large loop feedback to improve frequency response and harmonic distortion indicators amplifier

, but the impact on the transient characteristics of the amplifier and some dynamic indicators is more harm than good, especially the speaker on the induction voltage feedback to the previous level, can cause signal distortion, a hi-fi amplifier circuit described in this article is to remove the large loop feedback, and use the full symmetry of the DC differential preamp with constant emitter source circuit, good stability, good linearity, the LF356 bit output DC servo circuit can automatically maintain its output terminal potential, the whole circuit shown in Figure 4-16 (power source and protection circuitry omitted)
