Stereo microphone amplifier

The magnification of very weak audio-frequency signals is and remains a precarious affair. That is why a microphone amplifier good enough for professional applications must have balanced inputs and indisputably good specifications. Foremost, of course, is the faithful transducing of sound. Although this is a subjective aspect, it is confidently expected that the design of the amplifier described here will satisfy even professional audio engineers and technicians. It is a stereo model with integral phantom power supply for electric microphones.
