Small Signal Amplifier (Pre-Amplifier) For Audio Signal
The Stereo small level audio signal amplifier has been developed to amplify the low level stereo audio signal, without changing other parameters of the waveform such as frequency and shape of the signal. This circuit has been designed to amplify signals in the range of 20Hz to 20 kHz. Circuit amplify the low level signals from microphones, ultra-sonic transducer and
