No.10.0前级(图1)和No.8.0B后级(图2)的主放大电路均采用了北京羽商电声技术有限公司的一款注册专利电路(专利权人:于建兵)。该专利电路的设计开发主要考虑了心理声学因素对主观听音的影响。电路简洁,声音取向优美动听。现将专利电路主要内容介绍如下: 单端共集共射组态电压放大器和双向零极点补偿网络(见图7) 在晶体管音频放大器中,非线性失真、谐波失真最大的放大级是电压放大器。因此,改善该级的特性将会对整机性能起到重要的贡献。基于此,本电路主要从改善电压放大器
No.10.0 pre-stage (Figure 1) and No.8.0B after the stage (Figure 2) the main amplifier circuit are used in Beijing Yu Business Electro-acoustic Technology Co., Ltd. registered a patented circuit (patentee: Yu Jianbing) . The design and development of the patented circuit mainly considers the influence of psychoacoustic factors on the subjective listening. The circuit is concise, the sound direction is beautiful and beautiful. Now the main contents of the patent circuit are described as follows: Single-ended total configuration of co-emitter configuration voltage amplifier and bidirectional zero-pole compensation network (see Figure 7) In the transistor audio amplifier, the largest distortion of nonlinear distortion, harmonic distortion amplifier voltage amplifier . Therefore, improving the characteristics of this level will make an important contribution to the overall performance. Based on this, the circuit mainly from improving the voltage amplifier
