The 5mV of the audio signal which comes from the microphone to linear amplificated by the audio signals amplifier,then mixes with music signals from other sound sources(eg:the tape 、CD) by the hybird amplifier . By the control of the digital volume controller the mixed signal ,then amplificated again by the preamplifier,when integrated power amplifier for idling time realizes the signal enlargement factor respectively is 10、100、1000 times;moreover is capable of delivering 3V of output to a 600%26Omega; load. the amplificate signal makes the loudhailer work at last.

该音频信号放大器能够将来自话筒5mV的音频信号进行线性放大，然后和来自其他音源的音乐信号通过混合放大器来混合，混合后的信号经数字音量控制器对高低频的增益进行提升与衰减，再通过前置放大器放大，当集成功率放大器为空载的时候实现信号的放大倍数分别为10、100、1000倍；另外再实现当负载为600%26Omega；的时候，输出幅度为3V，最后经扬声器发出悦耳的声音。

The advantages of this invention are the following: backmixing non-conjugated grating pair Martinez impulse stretcher and compressor are applied in the multiple-pass enlarger with material of low dispersion and can effectively compensate the material dispersion in the enlarger and reduces the deformation of femtosecond impulse.
